AGENCY:
SUMMARY: These special conditions are
issued for a Boeing Model 767–300
airplane modified by Jet Aviation
Engineering Services (JAES), Spring
Branch, Texas. This modified airplane
will have a novel or unusual design
feature when compared to the state of
technology envisioned in the
airworthiness standards for transport
category airplanes. The modification is
associated with a forward lower deck
compartment that will serve as both a
service compartment and a Class C
cargo compartment. The applicable
airworthiness regulations do not contain
adequate or appropriate safety standards
for this design feature. These special
conditions contain the additional safety
standards that the Administrator
considers necessary to establish a level
of safety equivalent to that established
by the existing airworthiness standards.
DATES: The effective date of these
special conditions is February 14, 2005.

Federal Register / Vol. 70, No. 9 / Thursday, January 13, 2005 / Rules and Regulations
Background
On December 4, 2003, Jet Aviation
Engineering Services (JAES) applied for
a supplemental type certificate that
would allow modification of a Boeing
Model 767–300 airplane interior to an
executive jet interior configuration.
Boeing Model 767–300 series airplanes,
currently approved under Type
Certificate A1NM, are large transport
category airplanes with a main
passenger deck limited to 290
passengers or fewer, depending on the
interior configuration. As part of the
type design, certified Class C cargo
compartments are installed below the
main deck.
Jet Aviation Engineering Services
proposes to include as part of the
interior STC modification, access to the
forward lower deck Class C cargo
compartment and to convert that
compartment for use as a combined
service compartment and Class C cargo
compartment (service/cargo
compartment). Access will be provided
by two hatches installed in the cabin
floor, a primary hatch in the galley and
a secondary hatch located in the crew
rest area. A ladder will be installed at
each hatch to provide access from the
hatch to the forward lower deck service
compartment floor.
Access would be limited to one
trained crewmember and would be
allowed during level flight, but would
not be allowed during taxi, takeoff and
landing or during a fire.
As part of the safety enhancement
necessary to allow occupancy of the
forward lower deck service/cargo
compartment by a crewmember, JAES
proposes the installation of warning and
emergency equipment, as defined for a
lower lobe service compartment in 14
CFR 25.819. Speakers, warning lights,
and buzzers will be installed in the
forward lower deck service/cargo
compartment to warn an occupant of
turbulent conditions, the presence of
smoke or fire, or the need to leave the
area. A crew interphone will be
provided for communications with the
flightdeck.
Jet Aviation Engineering Services
indicates that the forward lower deck
service/cargo compartment will meet
the Class C cargo requirements of
§§ 25.855 and 25.857. The compartment
will be built using materials meeting the
flammability standards for Class C cargo
compartments and will have a smoke
detection system. The compartment will
be equipped with an approved built-in
fire suppression system, which is
controllable from the cockpit to
eliminate the need to send someone into
the compartment to fight a fire. In the
VerDate jul<14>2003
14:42 Jan 12, 2005
Jkt 205001
event of a fire, the forward lower deck
service/cargo compartment will be
evacuated, and the pilot will activate
the built-in fire suppression system. A
means will be provided to prevent
inadvertent access to the compartment
when the fire suppression system has
been activated.
Current regulations specify the
requirements for a forward lower deck
service compartment (§ 25.819) and a
Class C cargo compartment (§§ 25.855
and 25.857) but the regulations did not
envision a dual-purpose compartment.
Currently, § 25.819 specifies that a
service compartment may be occupied
and does not need to be evacuated
under certain normal conditions or
under certain unsafe conditions (e.g., in
the case of fire, the occupant could
function as a firefighter). The fire
control system of a service
compartment, however, would not
utilize a flood-type fire suppressant,
since the compartment might be
occupied. Section 25.857, however,
specifies that a Class C cargo
compartment have a fire detection
system and a built-in fire suppression
system, i.e., a total flood system. The
applicant intends to use the
compartment as a dual-purpose service/
cargo compartment and intends for the
operator to use the built-in systems to
fight fires in every instance.
The concept of a multi-use
compartment, which JAES proposes,
would be acceptable if the FAA could
be assured that whether the
compartment is used as a service
compartment or as a Class C cargo
compartment, the level of safety would
be equivalent to that of a separate
service compartment or a separate Class
C cargo compartment. Therefore, special
conditions that provide an equivalent
level of safety are being required. These
special conditions pertain to visible and
audible warnings, placards and
limitations, equipment, evacuation
routes, training, and the use of ladders
between the main deck and the forward
lower deck service/cargo compartment.
Type Certification Basis
Under the provisions of 14 CFR
21.101, Jet Aviation Engineering
Services must show that the Boeing
Model 767–300 airplane, as modified,
continues to meet the applicable
provisions of the regulations
incorporated by reference in Type
Certificate A1NM or the applicable
regulations in effect on the date of
application for the change.
The regulations incorporated by
reference in the type certificate are
commonly referred to as the ‘‘original
type certification basis.’’ The regulations
PO 00000
Frm 00002
Fmt 4700
Sfmt 4700
incorporated by reference in Type
Certificate A1NM for the Boeing Model
767–300 series airplanes include 14 CFR
part 25, as amended by Amendments
25–1 through 25–37 with certain
additions and special conditions as
listed in the type certificate data sheet.
The U.S. type certification basis for the
Boeing Model 767–300 series airplane is
established in accordance with §§ 21.17
and 21.21 and the type certification
application date.
The type certification basis listed in
Type Certificate Data Sheet No. A1NM,
for the Boeing Model 767–300 does not
include § 25.819, which was introduced
in Amendment 25–53. In this case,
§ 25.819 does provide appropriate safety
standards for that portion of this STC’s
design considered a service
compartment. Therefore, in lieu of
applying the requirements of § 25.819 as
a special condition, § 25.819
(Amendment 25–110) will be added as
a requirement to this STC’s certification
basis.
If the Administrator finds that the
applicable airworthiness regulations
(i.e., 14 CFR part 25) do not contain
adequate or appropriate safety standards
for a Boeing Model 767–300 series
airplane because of a novel or unusual
design feature, special conditions are
prescribed under the provisions of
§ 21.16.
In addition to the applicable
airworthiness regulations and special
conditions, the Boeing Model 767–300
must comply with the fuel vent and
exhaust emission requirements of 14
CFR part 34 and the noise certification
requirements of 14 CFR part 36.
Special conditions, as defined in 14
CFR 11.19, are issued in accordance
with § 11.38 and become part of the type
certification basis in accordance with
§ 21.101.
Special conditions are initially
applicable to the model for which they
are issued. Should the applicant apply
for a supplemental type certificate to
modify any other model included on the
same type certificate to incorporate the
same novel or unusual design feature,
the special conditions would also apply
to the other model under the provisions
of § 21.101.
Novel or Unusual Design Features
The Boeing Model 767–300 airplane
will incorporate a novel or unusual
design feature; specifically, the forward
lower deck compartment will be used as
a combined service compartment and
Class C cargo compartment.
Discussion
To allow the use of a dual-purposed
service/cargo compartment, these
E:\FR\FM\13JAR1.SGM
13JAR1
Federal Register / Vol. 70, No. 9 / Thursday, January 13, 2005 / Rules and Regulations
special conditions require certain
visible and audible warnings, placards
and limitations, equipment, and
training. The applicant has not
proposed a means of satisfying
regulatory requirements governing
occupancy of the forward lower deck
service/cargo compartment during taxi,
takeoff, and landing. Therefore, the FAA
will specify appropriate limitations for
such occupancy. A discussion of each
specific special condition follows but is
limited where the specific special
condition is self-explanatory:
Special Condition 1—Visible and
Audible Warnings
To maintain the advantages of both a
service compartment and a Class C
cargo compartment, certain warnings
need to be provided.
Special Condition 1a requires a
visible advisory in the cockpit to notify
the flightcrew when the forward lower
deck service/cargo compartment is
occupied. The potential exists that the
forward lower deck service/cargo
compartment may inadvertently be
occupied when it should not be, such as
during taxi, takeoff or landing or during
certain emergencies. Special Condition
1a also ensures that the flightcrew is
aware that the forward lower deck
service/cargo compartment is occupied
in order that the flightcrew can take
appropriate action to evacuate the
compartment before flooding it with fire
suppressant. There must be a placard or
sign adjacent to the warning light which
indicates that the light means that the
compartment is occupied.
Special Condition 1b requires an ‘‘on/
off’’ visible warning placard stating ‘‘Do
Not Enter’’ (or similar words) placard to
be located on or near each hatch. The
location should be on the main deck
side of the hatch. The warning is to be
controlled from the flightdeck to
prevent someone from entering the
forward lower deck service/cargo
compartment when it should not be
occupied; such as during taxi, takeoff or
landing, or when smoke or fire has been
detected. Opening the door during a fire
would degrade the effectiveness of the
fire suppressant and allow smoke,
flame, and/or fire suppressant into the
cabin.
Special Condition 1c requires a
visible and audible warning in the
forward lower deck service/cargo
compartment to notify an occupant that
he or she must leave the compartment.
This warning must be one which can be
seen and heard from any part of the
compartment. The visible and audible
warning is to be controlled from the
flightdeck. Because the forward lower
deck service/cargo compartment may be
VerDate jul<14>2003
14:42 Jan 12, 2005
Jkt 205001
occupied on the ground or in the air, a
warning must be provided to notify an
occupant to leave the compartment
prior to taxi, takeoff or landing or during
certain emergencies (other than fire,
which is dealt with under Special
Condition 1e). A visible warning is
required, in case the audible warning
becomes masked or distorted by engine,
equipment, or ground noises.
Special condition 1d requires a visible
and audible warning in the forward
lower deck service/cargo compartment
to notify an occupant of the need to use
a portable oxygen bottle in the event of
decompression. This warning must be
one which can be seen and heard from
any part of the compartment and must
be distinct from other warnings in the
compartment to prevent confusion and
to elicit correct action. The
decompression warning must be
automatic (i.e., not require separate
crew action) to ensure that an occupant
of the forward lower deck service/cargo
compartment does not delay putting on
the mask attached to the portable
oxygen bottle. This section of the
special conditions is partially in lieu of
the visible effect provided by the
automatic presentation feature required
by § 25.1447.
Special Condition 1e requires a
visible and audible warning in the
forward lower deck service/cargo
compartment when a fire is detected to
notify an occupant that he or she must
evacuate the compartment. The warning
must be one which can be seen and
heard from any part of the compartment
and must be distinct from other
warnings in the compartment in order to
prevent confusion and to elicit the
correct actions. The fire or smoke
detection warning must be automatic
(i.e., not require or depend on separate
crew action) to ensure that an occupant
of the forward lower deck service/cargo
compartment leaves before the
flightdeck crew releases fire suppressant
in the compartment.
Special Condition 2—Placards and
Limitations
The forward lower deck service/cargo
compartment must be evacuated if a fire
occurs. In addition, there must be a way
to prevent access into the compartment
during taxi, takeoff or landing or in the
event of a fire. Placards and limitations
are specified for these situations.
Special Condition 2a requires a
placard to be located outside each hatch
to the forward lower deck service/cargo
compartment, indicating that access is
limited to one crewmember trained in
evacuation procedures.
Special Condition 2b requires
placards to be located inside and
PO 00000
Frm 00003
Fmt 4700
Sfmt 4700
2327
outside each hatch of the forward lower
deck service/cargo compartment,
indicating that the compartment hatch
must remain closed, except when
someone is entering or leaving the
compartment. The hatches should
remain closed except for entering or
leaving the compartment so as to not
degrade the fire detection and
suppression systems, which are tested
and certified with the compartment
hatches closed. Further, with this
limitation there is less chance someone
will accidentally step through an open
hatch.
Special Condition 2c requires a
limitation to be placed in the airplane
flight manual (AFM) and placards to be
posted inside and outside the hatches of
the forward lower deck service/cargo
compartment, all stating that (1) the
compartment may not be occupied
during taxi, takeoff, or landing or during
a fire and (2) only authorized personnel
are permitted access. These placards are
being required, because the
compartment is not being certified for
occupancy during taxi, takeoff, or
landing and because the compartment
must not be occupied during a fire so
that an occupant is not exposed to fire
or to fire suppressant. These placards
are somewhat redundant, given the
warning required under Special
Conditions 1b and 1c but would provide
information to an occupant, if the
flightcrew failed to activate the
warnings of Special Conditions 1b and
1c.
Special Condition 2d requires in the
AFM (or AFM supplement) instructions
for the flightcrew to follow regarding—
(1) Permissible access and occupancy;
(2) The need to exit (or evacuate in
the event of an incapacitated person)
and discharge (flood) extinguishing
agent in the compartment; and
(3) The need, after decompression
warning, to immediately don the oxygen
mask and exit the compartment.
These requirements are to ensure that
a single member of the crew could
access the cargo compartment safely
during flight and exit safely during
failure conditions.
Special Condition 2e. Because access
is being provided to the forward lower
deck service/cargo compartment, there
is concern that during flight, passengers
may retrieve hazardous materials or
weapons stored in luggage. Access
could be prevented by locking the
forward lower deck service/cargo
compartment, and that is being
specified as one solution (in Special
Condition 2e(1)). However, this airplane
is being designed for use by a head-ofstate, it will have limited access, and it
will have placards limiting access.
E:\FR\FM\13JAR1.SGM
13JAR1
2328
Federal Register / Vol. 70, No. 9 / Thursday, January 13, 2005 / Rules and Regulations
Furthermore, there will be notification
to the flightcrew when the forward
lower deck service/cargo compartment
is occupied (in Special Condition 1a).
Special Condition 2e(2), therefore,
would prohibit the airplane from being
operated for hire or offered for common
carriage.
Special Condition 3—Equipment
In addition to that required by
§ 25.819, Special Condition 3 requires
the following equipment:
Special Condition 3a requires that
two portable oxygen bottles be readily
available at all times and that each be
sufficient to supply a member of the
crew who is occupying the forward
lower deck service/cargo compartment
(except during taxi, takeoff, or landing,
or during a fire). The supply of oxygen
must be compatible with the emergency
descent profile following a
decompression. Because it would not be
advisable to provide drop-down masks
in a cargo compartment or to store a
portable oxygen bottle in the
compartment, the FAA is requiring that
a portable oxygen bottles be mounted
outside and near the main deck entrance
of the forward lower deck service/cargo
compartment. A member of the crew
must carry the portable oxygen bottle,
when he or she enters the compartment.
The second bottle is for a second
crewmember’s use who must evacuate
an incapacitated crewmember.
Special Condition 3b requires
supplemental handheld lighting (with
locator light) when an occupant enters
the forward lower deck service/cargo
compartment and any of the following
three conditions exist: (1) Power to the
compartment is off, (2) the emergency
escape path lighting is off or lost, or (3)
visibility is poor. At least two flashlights
are required. One flashlight would be
located adjacent to each emergency exit
in the forward lower deck service/cargo
compartment at the foot of the stairs in
the compartment. Note that this
requirement is in addition to the
automatic emergency lighting system
required by § 25.819(a).
Special Condition 4—Evacuation Routes
To allow the forward lower deck
service/cargo compartment to be
utilized as a service compartment,
Special Condition 4 requires a
limitation to keep the two evacuation
routes required under § 25.819(a) clear
for evacuation. The cargo in the
compartment must be restrained to
ensure that the crewmember’s paths to
the exits are clear. Further, all entrances
and exits (hatches) from the forward
lower deck service/cargo compartment
must be capable of being opened and
VerDate jul<14>2003
14:42 Jan 12, 2005
Jkt 205001
closed, without obstruction. This allows
exiting under emergency conditions.
Further, the hatches must be able to be
closed to maintain the integrity of the
compartment with respect to fire
detection and with respect to smoke,
fire and extinguishing agent
containment requirements applicable to
the Class C cargo compartment,
including §§ 25.855, 25.857, and 25.858.
Also see Special Condition 2b.
Special Condition 5—Training
Because the design features required
by these special conditions can fulfill
their safety objectives only if
crewmembers are properly trained in
their use, these special conditions
require the applicant to develop the
following training materials:
Special Condition 5a requires training
materials about use of the forward lower
deck service/cargo compartment and
actions associated with the warnings
and placards required by these special
conditions.
Special Condition 5b requires training
materials about entering and exiting the
forward lower deck service/cargo
compartment, including emergency
exiting, (associated with Special
Conditions 1b, 1c, 1d, 1e, 2a, 2b, 2c, 2d,
and 3a).
Special Condition 5c requires training
materials about checking the pressure of
the portable oxygen bottle prior to
entering the forward lower deck service/
cargo compartment (associated with
Special Condition 3a).
Special Condition 5d requires training
materials about carrying a portable
oxygen bottle when entering the forward
lower deck service/cargo compartment
(associated with Special Condition 3a).
Special Condition 5e requires training
materials about maintaining an exit aisle
and access to the evacuation routes from
the lower lobe service/cargo
compartment (associated with Special
Condition 2f and 4).
Special Condition 5f requires a
limitation in the AFM (or AFM
supplement) stating all personnel
accessing the forward lower deck
service/cargo compartment must be
trained in the procedures specified
above. Special Condition 5f also states
there should be at least two
crewmembers (not the pilot or co-pilot)
trained in emergency evacuation
procedures. The second person is to aid
the evacuation of an incapacitated
crewmember should that occur.
Special Condition 6—Ladders
The ladders between the forward
lower deck service/cargo compartment
and the main deck must meet the
following requirements:
PO 00000
Frm 00004
Fmt 4700
Sfmt 4700
Special Condition 6a requires that
each ladder consist of a single segment
(to minimize potential errors of use).
Special Condition 6b requires that the
ladders have essentially rectangular
treads (to reduce the potential to slip).
Special Condition 6c requires that
general illumination of at least 0.05 footcandle, when measured along the
centerlines of each tread, be provided,
when the ladders are to be used (to
facilitate evacuation and reduce misssteps).
Applicability
As discussed above, these special
conditions are applicable to the Boeing
Model 767–300 airplane. Should JAES
apply at a later date for a supplemental
type certificate to modify any other
model included on Type Certificate
A1NM to incorporate the same novel or
unusual design feature, the special
conditions would apply to that model as
well under the provisions of § 21.101.
Conclusion
This action affects only certain novel
or unusual design features on one model
of airplane. It is not a rule of general
applicability, and it affects only the
applicant which applied to the FAA for
approval of these features on the
airplane.
Under standard practice, the effective
date of final special conditions would
be 30 days after the date of publication
in the Federal Register. However, as the
certification date for the Boeing Model
767–300, as modified by JAES, is
imminent, the FAA finds, that good
cause exists to make these special
conditions effective upon issuance.

1. Visible and Audible Warnings
In addition to the audible warnings
(fire/smoke detection and
E:\FR\FM\13JAR1.SGM
13JAR1
Federal Register / Vol. 70, No. 9 / Thursday, January 13, 2005 / Rules and Regulations
decompression) required by § 25.819(c),
the following warnings are required:
a. A visible advisory in the cockpit to
notify the flightcrew when the forward
lower deck service/cargo compartment
is occupied. The advisory light must be
accompanied by a placard or message
indicating that the compartment is
occupied.
b. A (on/off) visible warning placard
stating ‘‘Do Not Enter’’ (or similar
words) to be located on or near each
hatch. The location should be on the
main deck side of the hatch. The
warning is to be controlled from the
flightdeck.
c. A visible and audible warning in
the forward lower deck service/cargo
compartment to notify an occupant
when he or she must evacuate the
compartment. The warning must be one
which can be seen and heard from any
part of the compartment. The warning is
to be controlled from the flightdeck.
d. A visible and audible warning in
the forward lower deck service/cargo
compartment, which in the event of
decompression, warns an occupant of
the need to use a portable oxygen bottle.
This warning must be one which can be
seen and heard from any part of the
compartment and must be distinct from
other warnings in the compartment. The
decompression warning must be
automatic (i.e., not require separate
crew action), to ensure that an occupant
of the forward lower deck service/cargo
compartment does not delay using a
portable oxygen bottle. This section of
the special conditions is partially in lieu
of the visible effect provided by the
automatic presentation feature required
by § 25.1447.
e. A visible and audible warning in
the forward lower deck service/cargo
compartment, which in the event of a
fire, warns an occupant of the need to
evacuate the compartment. This
warning must be one which can be seen
and heard from any part of the
compartment and should be distinct
from other warnings in the
compartment. The fire or smoke
detection warning must be automatic
(i.e., not require a separate crew action)
to ensure that an occupant of the
forward lower deck service/cargo
compartment leaves before the
flightdeck crew releases fire
suppressant.
2. Placards and Limitations
In addition to those required in part
25, the following placards and
limitations are required:
a. A placard located outside each
hatch to the forward lower deck service/
cargo compartment, indicating that
access to the compartment is limited to

a fire, and (2) only authorized personnel
are permitted access.
d. Instructions in the AFM (or AFM
supplement) for the flightcrew to follow
regarding—
(1) Permissible access and occupancy
of the forward lower deck service/cargo
compartment;
(2) The need to exit (or evacuate in
the event of an incapacitated person)
and discharge (flood) extinguishing
agent in the compartment; and
(3) The need, after decompression
warning, to immediately don the oxygen
mask and exit the compartment.
e. A Limitation in the AFM
supplement stating that:
‘‘Carriage of hazardous material and/
or weapons in the forward lower deck
service/cargo compartment is prohibited
unless the following conditions are met:
(1) The forward lower deck service
compartment is locked during flight,
and the key remains with the flightcrew,
or
(2) The airplane is not operated for
hire or offered for common carriage.
This provision does not preclude the
operator from receiving remuneration to
the extent consistent with 14 CFR part
125, and 14 CFR part 91, and subpart F,
as applicable.’’
3. Equipment
In addition to that required by
§§ 25.819, the following equipment is
required:
a. Two portable oxygen bottles with
masks must be readily available outside
and near the primary main deck
entrance (hatch) of the forward lower
deck service/cargo compartment. Either
portable oxygen bottle must be
sufficient to supply a member of the
crew who is occupying the forward
lower deck service/cargo compartment
and a bottle with mask attached must be
carried by the crewmember when in the
compartment. The second bottle is for
the crewmember’s use who must
evacuate an incapacitated crewmember.

emergency illumination required by
§ 25.819(a). At least two flashlights,
each equipped with a locator light, must
be provided. A flashlight must be
located adjacent to each emergency exit
(hatch) at the foot of the ladder in the
forward lower deck service/cargo
compartment.
4. Evacuation Routes
A limitation must be placed in the
AFM (or AFM supplement) stating that:
When the forward lower deck service/
cargo compartment is operated as a
service compartment, the two
evacuation routes must be kept clear,
the special storage pallets/containers
must be installed, no loose storage is
permitted, and all items stored in the
compartment must be stored in
appropriate pallets/containers (or
similar words).
Similar loading restrictions should be
placed in the weight and balance
manual.
5. Training
Training manuals must be provided
for authorized crewmembers that may
enter the forward lower deck service/
cargo compartment and the manuals
and training shall include:
a. Use of the forward lower deck
service/service compartment and

AGENCY:
SUMMARY: The FAA is revising an
existing airworthiness directive (AD) for
certain Boeing Model 757–200 and
–200PF series airplanes. That AD
currently requires inspections,
adjustments, and functional checks of
the engine thrust reverser system; and
modification of the engine thrust
reverser directional control valve. That
AD also requires installation of an
additional thrust reverser locking
feature and periodic functional tests of
the locking feature following
installation. This new AD retains the
requirements of the existing AD, but
removes certain tests and inspections
for certain airplanes. This AD is
prompted by a determination of an error
in the existing AD. We are issuing this
AD to prevent deployment of a thrust
reverser in flight and subsequent
reduced controllability of the airplane.
DATES: Effective January 28, 2005.
The incorporation by reference of
certain publications, as listed in the

SUPPLEMENTARY INFORMATION: On August
7, 2003, we issued AD 94–01–10 R1,
amendment 39–13247 (68 FR 48546,
August 14, 2003). That AD applies to
certain Boeing Model 757–200 and
–200PF series airplanes. That AD
requires inspections, adjustments, and
functional checks of the engine thrust
reverser system; and modification of the
engine thrust reverser directional
control valve. That AD also requires
installation of an additional thrust
reverser locking feature and periodic
functional tests of the locking feature
following installation. That AD was
prompted by a determination that the
applicability of AD 94–01–10,
amendment 39–8792 (59 FR 4558,
February 1, 1994), should be limited to
Boeing Model 757–200 and –200PF
series airplanes equipped with Pratt and
Whitney PW2000 series engines. The
actions specified in the AD are intended
to prevent deployment of a thrust
reverser in flight and subsequent
reduced controllability of the airplane.
Actions Since AD Was Issued
We have since determined that
paragraph (c) of AD 94–01–10 R1 should
be revised to apply only to airplanes
with line numbers 441 and lower. That
AD applies to Boeing Model 757 series
airplanes with Pratt & Whitney PW2000
series engines. The airplanes in that AD
are divided into two groups:
• Airplanes without a thrust reverser
sync lock (airplane line numbers 1
through 441 inclusive); and
• Airplanes with changes to the sync
lock installation done in production
(airplane line numbers 442 and
subsequent).
When we issued that AD, we made
changes as a result of comments we
received. One of the changes was to
change paragraph (d) to apply only to
airplanes without a thrust reverser sync
lock installed in production. The action
in paragraph (d) (installing the thrust
reverser sync lock) is terminating action
for paragraphs (a) through (c). We
intended for the repetitive tests and
inspections in paragraph (c) to apply
only to airplanes without a thrust
reverser sync lock installed during
production. Unlike paragraph (d),
however, paragraph (c) of that AD
incorrectly applies to all line numbers
of airplanes, including those with
changes to the sync lock installation
done in production.
Therefore, we have changed
paragraph (c) of this final rule to clarify

Special Conditions: Boeing Model 767-300 Airplane; Forward Lower
Deck Service/Cargo Compartment
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final special conditions; request for comments.
-----------------------------------------------------------------------
SUMMARY: These special conditions are issued for a Boeing Model 767-300
airplane modified by Jet Aviation Engineering Services (JAES), Spring
Branch, Texas. This modified airplane will have a novel or unusual
design feature when compared to the state of technology envisioned in
the airworthiness standards for transport category airplanes. The
modification is associated with a forward lower deck compartment that
will serve as both a service compartment and a Class C cargo
compartment. The applicable airworthiness regulations do not contain
adequate or appropriate safety standards for this design feature. These
special conditions contain the additional safety standards that the
Administrator considers necessary to establish a level of safety
equivalent to that established by the existing airworthiness standards.
DATES: The effective date of these special conditions is February 14,
2005.
Comments must be received on or before February 28, 2005.
ADDRESSES: Comments on these special conditions may be mailed in
duplicate to: Federal Aviation Administration, Transport Airplane
Directorate, Attention: Rules Docket (ANM-113), Docket No. NM299, 1601

SUPPLEMENTARY INFORMATION: The FAA has determined that notice and
opportunity for prior public comment hereon are impracticable, because
those procedures would significantly delay issuance of the approval
design and thus delivery of the affected aircraft. The FAA, therefore,
finds that good cause exists for making these special conditions
effective upon issuance.
Comments Invited
Interested persons are invited to submit such written data, views,
or arguments as they may desire. Comments should identify the rules
docket number and be submitted in duplicate to the address specified
above. The Administrator will consider all comments received on or
before the closing date for comments. The special conditions may be
changed in light of the comments received. All comments received will
be available in the Rules Docket for examination by interested persons,
both before and after the closing date for comments. A report
summarizing each substantive public contact with FAA personnel
concerning this rulemaking will be filed in the docket. Persons wishing
the FAA to acknowledge receipt of their comments submitted in response
to these special conditions must include with those comments a self-
addressed postcard on which the following statement is made: ``Comments

Background
On December 4, 2003, Jet Aviation Engineering Services (JAES)
applied for a supplemental type certificate that would allow
modification of a Boeing Model 767-300 airplane interior to an
executive jet interior configuration. Boeing Model 767-300 series
airplanes, currently approved under Type Certificate A1NM, are large
transport category airplanes with a main passenger deck limited to 290
passengers or fewer, depending on the interior configuration. As part
of the type design, certified Class C cargo compartments are installed
below the main deck.
Jet Aviation Engineering Services proposes to include as part of
the interior STC modification, access to the forward lower deck Class C
cargo compartment and to convert that compartment for use as a combined
service compartment and Class C cargo compartment (service/cargo
compartment). Access will be provided by two hatches installed in the
cabin floor, a primary hatch in the galley and a secondary hatch
located in the crew rest area. A ladder will be installed at each hatch
to provide access from the hatch to the forward lower deck service
compartment floor.
Access would be limited to one trained crewmember and would be
allowed during level flight, but would not be allowed during taxi,
takeoff and landing or during a fire.
As part of the safety enhancement necessary to allow occupancy of
the forward lower deck service/cargo compartment by a crewmember, JAES
proposes the installation of warning and emergency equipment, as
defined for a lower lobe service compartment in 14 CFR 25.819.
Speakers, warning lights, and buzzers will be installed in the forward
lower deck service/cargo compartment to warn an occupant of turbulent
conditions, the presence of smoke or fire, or the need to leave the
area. A crew interphone will be provided for communications with the
flightdeck.
Jet Aviation Engineering Services indicates that the forward lower
deck service/cargo compartment will meet the Class C cargo requirements
of Sec. Sec. 25.855 and 25.857. The compartment will be built using
materials meeting the flammability standards for Class C cargo
compartments and will have a smoke detection system. The compartment
will be equipped with an approved built-in fire suppression system,
which is controllable from the cockpit to eliminate the need to send
someone into the compartment to fight a fire. In the event of a fire,
the forward lower deck service/cargo compartment will be evacuated, and
the pilot will activate the built-in fire suppression system. A means
will be provided to prevent inadvertent access to the compartment when
the fire suppression system has been activated.
Current regulations specify the requirements for a forward lower
deck service compartment (Sec. 25.819) and a Class C cargo compartment
(Sec. Sec. 25.855 and 25.857) but the regulations did not envision a
dual-purpose compartment. Currently, Sec. 25.819 specifies that a
service compartment may be occupied and does not need to be evacuated
under certain normal conditions or under certain unsafe conditions
(e.g., in the case of fire, the occupant could function as a
firefighter). The fire control system of a service compartment,
however, would not utilize a flood-type fire suppressant, since the
compartment might be occupied. Section 25.857, however, specifies that
a Class C cargo compartment have a fire detection system and a built-in
fire suppression system, i.e., a total flood system. The applicant
intends to use the compartment as a dual-purpose service/cargo
compartment and intends for the operator to use the built-in systems to
fight fires in every instance.
The concept of a multi-use compartment, which JAES proposes, would
be acceptable if the FAA could be assured that whether the compartment
is used as a service compartment or as a Class C cargo compartment, the
level of safety would be equivalent to that of a separate service
compartment or a separate Class C cargo compartment. Therefore, special
conditions that provide an equivalent level of safety are being
required. These special conditions pertain to visible and audible
warnings, placards and limitations, equipment, evacuation routes,
training, and the use of ladders between the main deck and the forward
lower deck service/cargo compartment.
Type Certification Basis
Under the provisions of 14 CFR 21.101, Jet Aviation Engineering
Services must show that the Boeing Model 767-300 airplane, as modified,
continues to meet the applicable provisions of the regulations
incorporated by reference in Type Certificate A1NM or the applicable
regulations in effect on the date of application for the change.
The regulations incorporated by reference in the type certificate
are commonly referred to as the ``original type certification basis.''
The regulations incorporated by reference in Type Certificate A1NM for
the Boeing Model 767-300 series airplanes include 14 CFR part 25, as
amended by Amendments 25-1 through 25-37 with certain additions and
special conditions as listed in the type certificate data sheet. The
U.S. type certification basis for the Boeing Model 767-300 series
airplane is established in accordance with Sec. Sec. 21.17 and 21.21
and the type certification application date.
The type certification basis listed in Type Certificate Data Sheet
No. A1NM, for the Boeing Model 767-300 does not include Sec. 25.819,
which was introduced in Amendment 25-53. In this case, Sec. 25.819
does provide appropriate safety standards for that portion of this
STC's design considered a service compartment. Therefore, in lieu of
applying the requirements of Sec. 25.819 as a special condition, Sec.
25.819 (Amendment 25-110) will be added as a requirement to this STC's
certification basis.
If the Administrator finds that the applicable airworthiness
regulations (i.e., 14 CFR part 25) do not contain adequate or
appropriate safety standards for a Boeing Model 767-300 series airplane
because of a novel or unusual design feature, special conditions are
prescribed under the provisions of Sec. 21.16.
In addition to the applicable airworthiness regulations and special
conditions, the Boeing Model 767-300 must comply with the fuel vent and
exhaust emission requirements of 14 CFR part 34 and the noise
certification requirements of 14 CFR part 36.
Special conditions, as defined in 14 CFR 11.19, are issued in
accordance with Sec. 11.38 and become part of the type certification
basis in accordance with Sec. 21.101.
Special conditions are initially applicable to the model for which
they are issued. Should the applicant apply for a supplemental type
certificate to modify any other model included on the same type
certificate to incorporate the same novel or unusual design feature,
the special conditions would also apply to the other model under the
provisions of Sec. 21.101.
Novel or Unusual Design Features
The Boeing Model 767-300 airplane will incorporate a novel or
unusual design feature; specifically, the forward lower deck
compartment will be used as a combined service compartment and Class C
cargo compartment.
Discussion
To allow the use of a dual-purposed service/cargo compartment,
these
[[Page 2327]]
special conditions require certain visible and audible warnings,
placards and limitations, equipment, and training. The applicant has
not proposed a means of satisfying regulatory requirements governing
occupancy of the forward lower deck service/cargo compartment during
taxi, takeoff, and landing. Therefore, the FAA will specify appropriate
limitations for such occupancy. A discussion of each specific special
condition follows but is limited where the specific special condition
is self-explanatory:
Special Condition 1--Visible and Audible Warnings
To maintain the advantages of both a service compartment and a
Class C cargo compartment, certain warnings need to be provided.
Special Condition 1a requires a visible advisory in the cockpit to
notify the flightcrew when the forward lower deck service/cargo
compartment is occupied. The potential exists that the forward lower
deck service/cargo compartment may inadvertently be occupied when it
should not be, such as during taxi, takeoff or landing or during
certain emergencies. Special Condition 1a also ensures that the
flightcrew is aware that the forward lower deck service/cargo
compartment is occupied in order that the flightcrew can take
appropriate action to evacuate the compartment before flooding it with
fire suppressant. There must be a placard or sign adjacent to the
warning light which indicates that the light means that the compartment
is occupied.
Special Condition 1b requires an ``on/off'' visible warning placard
stating ``Do Not Enter'' (or similar words) placard to be located on or
near each hatch. The location should be on the main deck side of the
hatch. The warning is to be controlled from the flightdeck to prevent
someone from entering the forward lower deck service/cargo compartment
when it should not be occupied; such as during taxi, takeoff or
landing, or when smoke or fire has been detected. Opening the door
during a fire would degrade the effectiveness of the fire suppressant
and allow smoke, flame, and/or fire suppressant into the cabin.
Special Condition 1c requires a visible and audible warning in the
forward lower deck service/cargo compartment to notify an occupant that
he or she must leave the compartment. This warning must be one which
can be seen and heard from any part of the compartment. The visible and
audible warning is to be controlled from the flightdeck. Because the
forward lower deck service/cargo compartment may be occupied on the
ground or in the air, a warning must be provided to notify an occupant
to leave the compartment prior to taxi, takeoff or landing or during
certain emergencies (other than fire, which is dealt with under Special
Condition 1e). A visible warning is required, in case the audible
warning becomes masked or distorted by engine, equipment, or ground
noises.
Special condition 1d requires a visible and audible warning in the
forward lower deck service/cargo compartment to notify an occupant of
the need to use a portable oxygen bottle in the event of decompression.
This warning must be one which can be seen and heard from any part of
the compartment and must be distinct from other warnings in the
compartment to prevent confusion and to elicit correct action. The
decompression warning must be automatic (i.e., not require separate
crew action) to ensure that an occupant of the forward lower deck
service/cargo compartment does not delay putting on the mask attached
to the portable oxygen bottle. This section of the special conditions
is partially in lieu of the visible effect provided by the automatic
presentation feature required by Sec. 25.1447.
Special Condition 1e requires a visible and audible warning in the
forward lower deck service/cargo compartment when a fire is detected to
notify an occupant that he or she must evacuate the compartment. The
warning must be one which can be seen and heard from any part of the
compartment and must be distinct from other warnings in the compartment
in order to prevent confusion and to elicit the correct actions. The
fire or smoke detection warning must be automatic (i.e., not require or
depend on separate crew action) to ensure that an occupant of the
forward lower deck service/cargo compartment leaves before the
flightdeck crew releases fire suppressant in the compartment.
Special Condition 2--Placards and Limitations
The forward lower deck service/cargo compartment must be evacuated
if a fire occurs. In addition, there must be a way to prevent access
into the compartment during taxi, takeoff or landing or in the event of
a fire. Placards and limitations are specified for these situations.
Special Condition 2a requires a placard to be located outside each
hatch to the forward lower deck service/cargo compartment, indicating
that access is limited to one crewmember trained in evacuation
procedures.
Special Condition 2b requires placards to be located inside and
outside each hatch of the forward lower deck service/cargo compartment,
indicating that the compartment hatch must remain closed, except when
someone is entering or leaving the compartment. The hatches should
remain closed except for entering or leaving the compartment so as to
not degrade the fire detection and suppression systems, which are
tested and certified with the compartment hatches closed. Further, with
this limitation there is less chance someone will accidentally step
through an open hatch.
Special Condition 2c requires a limitation to be placed in the
airplane flight manual (AFM) and placards to be posted inside and
outside the hatches of the forward lower deck service/cargo
compartment, all stating that (1) the compartment may not be occupied
during taxi, takeoff, or landing or during a fire and (2) only
authorized personnel are permitted access. These placards are being
required, because the compartment is not being certified for occupancy
during taxi, takeoff, or landing and because the compartment must not
be occupied during a fire so that an occupant is not exposed to fire or
to fire suppressant. These placards are somewhat redundant, given the
warning required under Special Conditions 1b and 1c but would provide
information to an occupant, if the flightcrew failed to activate the
warnings of Special Conditions 1b and 1c.
Special Condition 2d requires in the AFM (or AFM supplement)
instructions for the flightcrew to follow regarding--
(1) Permissible access and occupancy;
(2) The need to exit (or evacuate in the event of an incapacitated
person) and discharge (flood) extinguishing agent in the compartment;
and
(3) The need, after decompression warning, to immediately don the
oxygen mask and exit the compartment.
These requirements are to ensure that a single member of the crew
could access the cargo compartment safely during flight and exit safely
during failure conditions.
Special Condition 2e. Because access is being provided to the
forward lower deck service/cargo compartment, there is concern that
during flight, passengers may retrieve hazardous materials or weapons
stored in luggage. Access could be prevented by locking the forward
lower deck service/cargo compartment, and that is being specified as
one solution (in Special Condition 2e(1)). However, this airplane is
being designed for use by a head-of-state, it will have limited access,
and it will have placards limiting access.
[[Page 2328]]
Furthermore, there will be notification to the flightcrew when the
forward lower deck service/cargo compartment is occupied (in Special
Condition 1a). Special Condition 2e(2), therefore, would prohibit the
airplane from being operated for hire or offered for common carriage.
Special Condition 3--Equipment
In addition to that required by Sec. 25.819, Special Condition 3
requires the following equipment:
Special Condition 3a requires that two portable oxygen bottles be
readily available at all times and that each be sufficient to supply a
member of the crew who is occupying the forward lower deck service/
cargo compartment (except during taxi, takeoff, or landing, or during a
fire). The supply of oxygen must be compatible with the emergency
descent profile following a decompression. Because it would not be
advisable to provide drop-down masks in a cargo compartment or to store
a portable oxygen bottle in the compartment, the FAA is requiring that
a portable oxygen bottles be mounted outside and near the main deck
entrance of the forward lower deck service/cargo compartment. A member
of the crew must carry the portable oxygen bottle, when he or she
enters the compartment. The second bottle is for a second crewmember's
use who must evacuate an incapacitated crewmember.
Special Condition 3b requires supplemental handheld lighting (with
locator light) when an occupant enters the forward lower deck service/
cargo compartment and any of the following three conditions exist: (1)
Power to the compartment is off, (2) the emergency escape path lighting
is off or lost, or (3) visibility is poor. At least two flashlights are
required. One flashlight would be located adjacent to each emergency
exit in the forward lower deck service/cargo compartment at the foot of
the stairs in the compartment. Note that this requirement is in
addition to the automatic emergency lighting system required by Sec.
25.819(a).
Special Condition 4--Evacuation Routes
To allow the forward lower deck service/cargo compartment to be
utilized as a service compartment, Special Condition 4 requires a
limitation to keep the two evacuation routes required under Sec.
25.819(a) clear for evacuation. The cargo in the compartment must be
restrained to ensure that the crewmember's paths to the exits are
clear. Further, all entrances and exits (hatches) from the forward
lower deck service/cargo compartment must be capable of being opened
and closed, without obstruction. This allows exiting under emergency
conditions. Further, the hatches must be able to be closed to maintain
the integrity of the compartment with respect to fire detection and
with respect to smoke, fire and extinguishing agent containment
requirements applicable to the Class C cargo compartment, including
Sec. Sec. 25.855, 25.857, and 25.858. Also see Special Condition 2b.
Special Condition 5--Training
Because the design features required by these special conditions
can fulfill their safety objectives only if crewmembers are properly
trained in their use, these special conditions require the applicant to
develop the following training materials:
Special Condition 5a requires training materials about use of the
forward lower deck service/cargo compartment and actions associated
with the warnings and placards required by these special conditions.
Special Condition 5b requires training materials about entering and
exiting the forward lower deck service/cargo compartment, including
emergency exiting, (associated with Special Conditions 1b, 1c, 1d, 1e,
2a, 2b, 2c, 2d, and 3a).
Special Condition 5c requires training materials about checking the
pressure of the portable oxygen bottle prior to entering the forward
lower deck service/cargo compartment (associated with Special Condition
3a).
Special Condition 5d requires training materials about carrying a
portable oxygen bottle when entering the forward lower deck service/
cargo compartment (associated with Special Condition 3a).
Special Condition 5e requires training materials about maintaining
an exit aisle and access to the evacuation routes from the lower lobe
service/cargo compartment (associated with Special Condition 2f and 4).
Special Condition 5f requires a limitation in the AFM (or AFM
supplement) stating all personnel accessing the forward lower deck
service/cargo compartment must be trained in the procedures specified
above. Special Condition 5f also states there should be at least two
crewmembers (not the pilot or co-pilot) trained in emergency evacuation
procedures. The second person is to aid the evacuation of an
incapacitated crewmember should that occur.
Special Condition 6--Ladders
The ladders between the forward lower deck service/cargo
compartment and the main deck must meet the following requirements:
Special Condition 6a requires that each ladder consist of a single
segment (to minimize potential errors of use).
Special Condition 6b requires that the ladders have essentially
rectangular treads (to reduce the potential to slip).
Special Condition 6c requires that general illumination of at least
0.05 foot-candle, when measured along the centerlines of each tread, be
provided, when the ladders are to be used (to facilitate evacuation and
reduce miss-steps).
Applicability
As discussed above, these special conditions are applicable to the
Boeing Model 767-300 airplane. Should JAES apply at a later date for a
supplemental type certificate to modify any other model included on
Type Certificate A1NM to incorporate the same novel or unusual design
feature, the special conditions would apply to that model as well under
the provisions of Sec. 21.101.
Conclusion
This action affects only certain novel or unusual design features
on one model of airplane. It is not a rule of general applicability,
and it affects only the applicant which applied to the FAA for approval
of these features on the airplane.
Under standard practice, the effective date of final special
conditions would be 30 days after the date of publication in the
Federal Register. However, as the certification date for the Boeing
Model 767-300, as modified by JAES, is imminent, the FAA finds, that
good cause exists to make these special conditions effective upon
issuance.

The Special Conditions
0
Accordingly, pursuant to the authority delegated to me by the
Administrator, the following special conditions are issued as part of
the type certification basis for the Boeing Model 767-300 airplane,
modified by Jet Aviation Engineering Services, to include a forward
lower deck compartment configured for use as both a service compartment
and a Class C cargo compartment.
1. Visible and Audible Warnings
In addition to the audible warnings (fire/smoke detection and
[[Page 2329]]
decompression) required by Sec. 25.819(c), the following warnings are
required:
a. A visible advisory in the cockpit to notify the flightcrew when
the forward lower deck service/cargo compartment is occupied. The
advisory light must be accompanied by a placard or message indicating
that the compartment is occupied.
b. A (on/off) visible warning placard stating ``Do Not Enter'' (or
similar words) to be located on or near each hatch. The location should
be on the main deck side of the hatch. The warning is to be controlled
from the flightdeck.
c. A visible and audible warning in the forward lower deck service/
cargo compartment to notify an occupant when he or she must evacuate
the compartment. The warning must be one which can be seen and heard
from any part of the compartment. The warning is to be controlled from
the flightdeck.
d. A visible and audible warning in the forward lower deck service/
cargo compartment, which in the event of decompression, warns an
occupant of the need to use a portable oxygen bottle. This warning must
be one which can be seen and heard from any part of the compartment and
must be distinct from other warnings in the compartment. The
decompression warning must be automatic (i.e., not require separate
crew action), to ensure that an occupant of the forward lower deck
service/cargo compartment does not delay using a portable oxygen
bottle. This section of the special conditions is partially in lieu of
the visible effect provided by the automatic presentation feature
required by Sec. 25.1447.
e. A visible and audible warning in the forward lower deck service/
cargo compartment, which in the event of a fire, warns an occupant of
the need to evacuate the compartment. This warning must be one which
can be seen and heard from any part of the compartment and should be
distinct from other warnings in the compartment. The fire or smoke
detection warning must be automatic (i.e., not require a separate crew
action) to ensure that an occupant of the forward lower deck service/
cargo compartment leaves before the flightdeck crew releases fire
suppressant.
2. Placards and Limitations
In addition to those required in part 25, the following placards
and limitations are required:
a. A placard located outside each hatch to the forward lower deck
service/cargo compartment, indicating that access to the compartment is
limited to one crewmember trained in evacuation procedures.
b. A placard located inside and outside each hatch to the forward
lower deck service/cargo compartment, indicating that the compartment
hatches must remain closed, except when someone is entering or leaving
the compartment.
c. A limitation in the AFM and a placard located inside and outside
each hatch to the forward lower deck service/cargo compartment, all
stating that (1) the forward lower deck service/cargo compartment must
not be occupied during taxi, takeoff, or landing or during a fire, and
(2) only authorized personnel are permitted access.
d. Instructions in the AFM (or AFM supplement) for the flightcrew
to follow regarding--
(1) Permissible access and occupancy of the forward lower deck
service/cargo compartment;
(2) The need to exit (or evacuate in the event of an incapacitated
person) and discharge (flood) extinguishing agent in the compartment;
and
(3) The need, after decompression warning, to immediately don the
oxygen mask and exit the compartment.
e. A Limitation in the AFM supplement stating that:
``Carriage of hazardous material and/or weapons in the forward
lower deck service/cargo compartment is prohibited unless the following
conditions are met:
(1) The forward lower deck service compartment is locked during
flight, and the key remains with the flightcrew, or
(2) The airplane is not operated for hire or offered for common
carriage. This provision does not preclude the operator from receiving
remuneration to the extent consistent with 14 CFR part 125, and 14 CFR
part 91, and subpart F, as applicable.''
3. Equipment
In addition to that required by Sec. Sec. 25.819, the following
equipment is required:
a. Two portable oxygen bottles with masks must be readily available
outside and near the primary main deck entrance (hatch) of the forward
lower deck service/cargo compartment. Either portable oxygen bottle
must be sufficient to supply a member of the crew who is occupying the
forward lower deck service/cargo compartment and a bottle with mask
attached must be carried by the crewmember when in the compartment. The
second bottle is for the crewmember's use who must evacuate an
incapacitated crewmember.
b. Flashlights or other supplemental handheld lighting, in addition
to the emergency illumination required by Sec. 25.819(a). At least two
flashlights, each equipped with a locator light, must be provided. A
flashlight must be located adjacent to each emergency exit (hatch) at
the foot of the ladder in the forward lower deck service/cargo
compartment.
4. Evacuation Routes
A limitation must be placed in the AFM (or AFM supplement) stating
that:
When the forward lower deck service/cargo compartment is operated
as a service compartment, the two evacuation routes must be kept clear,
the special storage pallets/containers must be installed, no loose
storage is permitted, and all items stored in the compartment must be
stored in appropriate pallets/containers (or similar words).
Similar loading restrictions should be placed in the weight and
balance manual.
5. Training
Training manuals must be provided for authorized crewmembers that
may enter the forward lower deck service/cargo compartment and the
manuals and training shall include:
a. Use of the forward lower deck service/service compartment and
actions indicated by the warnings and placards specified herein.
b. Entering and exiting the forward lower deck service/cargo
compartment, including emergency exiting.
c. Checking the pressure of the portable oxygen bottle prior to
entering the forward lower deck service/cargo compartment.
d. Carrying a portable oxygen bottle when entering the forward
lower deck service/ cargo compartment.
e. Maintaining an exit aisle and access to evacuation routes from
the forward lower deck service/cargo compartment. Training must address
how to keep the evacuation routes clear, i.e., how to restrain cargo in
the compartment to ensure that the paths to the exits (hatches) are
clear.
f. A limitation in the AFM supplement stating that all personnel
accessing the forward lower deck service/cargo compartment must be
trained in the procedures listed above. To facilitate the evacuation of
an incapacitated person, there should be at least two crewmembers (not
the pilot or co-pilot) trained in the emergency procedures for the
forward lower deck service/cargo compartment.
6. Ladders
The following requirements must be met for ladders installed
between the
[[Page 2330]]
main deck and the forward lower deck service/cargo compartment:
a. Each ladder must consist of a single segment.
b. The ladders must have essentially rectangular treads.
c. General illumination of at least 0.05 foot-candle, when measured
along the centerlines of each ladder tread, must be provided when the
ladders are to be used.
