Background
On March 2, 2007, Jet Aviation
Engineering Services L.P. (JAES), of
Teterboro, New Jersey, applied for a
supplemental type certificate for a
reconfiguration of an aircraft interior in
a 747–468. The Boeing Model 747–468
airplane is FAA approved under Type
Certificate A20WE as a large transportcategory airplane that is limited to 660
passengers or fewer, depending on the
interior configuration.
This modification includes the
installation of a medical lift between the
main deck and upper deck. The lift
allows the transport of a single occupant
between the decks during cruise or
ramp operations. The applicable
airworthiness regulations do not contain
adequate or appropriate safety standards
for this design feature.
Type Certification Basis
Under the provisions of Title 14, Code
of Federal Regulations (14 CFR) 21.101,
JAES must show that the 747–468, as
changed, continues to meet the
applicable provisions of the regulations
incorporated by reference in Type
Certificate A20WE, or of 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 typecertification basis.’’ The regulations
incorporated by reference in Type
Certificate A20WE are as follows:
• Part 36, as amended by
Amendments 36–1 through 36–15, and
any later amendments in existence at
the time of certification.
• Special Federal Aviation Regulation
(SFAR) 27, as amended by Amendments
27–1 through 27–6 and any later
amendments in existence at the time of
type certification.
• Part 25, effective February 1, 1965,
as amended by Amendments 25–1
through 25–59, and the part 25 sectionnumber exceptions itemized in Type
Certificate A20WE.
The following special conditions,
exemptions, and equivalent safety
findings, which are part of the Model
747–300 certification basis, are also part
of the certification basis for the Model
747–400.
The special conditions include those
enclosed with an FAA letter to The
Boeing Company dated February 20,
1970, and the following:
1. Special Condition 4A, revised to
apply to airplanes with the landing-gear
load-evener system deleted, was
recorded as an enclosure to an FAA
letter to The Boeing Company dated
May 12, 1971.
2. Special Condition No. 25–61–NW–
1, for occupancy not to exceed 32
passengers on the upper deck of
airplanes with a spiral staircase, was
transmitted to The Boeing Company by
FAA letter dated February 26, 1975.
3. Special Condition No. 25–71–NW–
3, for occupancy not to exceed 45
passengers on the upper deck of
airplanes with a straight-segmented
stairway, was transmitted to The Boeing
Company by FAA letter dated

Boeing Company by FAA letter dated
July 8, 1977.
6. Special Condition No. 25–ANM–16,
for use of an overhead crew-rest area,
occupancy not to exceed ten
crewmembers, was transmitted to The
Boeing Company by FAA letter dated
November 19, 1987. The FAA-approved
procedures required for compliance
with paragraph 13 of the special
condition are located in Boeing
Document D926U303, Appendix D.
7. Special Condition No. 25–ANM–24,
applicable to flight-deck displays and
propulsion-control systems, was
provided to Boeing on December 22,
1988.
8. Special Condition No. 25–ANM–25,
which established lightning-and radiofrequency-energy protection
requirements, was provided to Boeing
on December 22, 1988.

Discussion
Novel or Unusual Design Features
mstockstill on DSKH9S0YB1PROD with PROPOSALS
If the Administrator finds that the
applicable airworthiness regulations
(i.e., 14 CFR part 25) do not contain
adequate or appropriate safety standards
for the 747–468 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 747–468 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.
The FAA issues special conditions, as
defined in 14 CFR 11.19, in accordance
with § 11.38, and they become part of
the type-certification basis under
§ 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 or similar novel or unusual design
feature, the special conditions would
also apply to the other model under
§ 21.101.
Aircraft, Aviation safety, Reporting
and recordkeeping requirements.
The authority citation for these
special conditions is as follows:
The original aircraft configuration
included a straight stairway between the
main deck and upper deck at FS 870.
The stairway is relocated in the new
configuration, and the existing stairway
is replaced with an electrically powered
medical lift using the opening in the
upper deck formerly occupied by the
stairs. When the lift is not in operation,
the upper-deck opening is covered by
floor panels. These floor panels are
opened up prior to operation of the lift
and form a protective fencing around
the upper-deck opening.
The purpose of the medical lift is to
move an occupant between the master
lounge in the upper deck and the
medical room on the lower deck.
The lift platform is driven by two
redundant electrical motors, mounted to
the rear wall, between the struts. A
lifting gear-drive with shafts and gear
boxes is powered on the front and rear
of the lift platform. The spindles are
supported at the lifting gear on the
lower support structure and with a strut
support on the upper deck. The lift
platform is guided in lateral directions
with the guiding rails mounted on the
struts.
VerDate Mar<15>2010
16:31 May 17, 2010
Jkt 220001
Due to the novel or unusual features
associated with the installation of this
medical lift, the following special
conditions are considered necessary to
provide a level of safety equal to that
established by the airworthiness
regulations incorporated by reference in
the type-certificate.
Applicability
As discussed above, these special
conditions are applicable to the 747–
468. Should JAES apply at a later date
for a supplemental type certificate to
modify any other model included on
Type Certificate A20WE, to incorporate
the same novel or unusual design
feature, the special conditions would
apply to that model as well.
Conclusion
This action affects only certain novel
or unusual design features on one model
of airplanes. It is not a rule of general
applicability and it affects only the
applicant who applied to the FAA for
approval of these features on the
airplane.

The Proposed Special Conditions
Accordingly, the Federal Aviation
Administration (FAA) proposes the
following special conditions as part of
the type-certification basis for Boeing
747–468 airplanes modified by JAES.
1. A functional verification must be
conducted to ensure the adequacy of the
lift design features that are supposed to
prevent injury to the lift occupant, lift
operator, and lift observer.
2. The occupied lift must be designed
to withstand the non-emergency load
conditions imposed by the aircraft
according to loads report SIE–327–301,
revision D.
3. Occupancy or operation of the lift
must not be permitted during taxi,
takeoff, landing (TTL), or turbulent
conditions.
4. The lift must be stowed for TTL.
The stowed position requires the lift
platform positioned at the main-deck
level with the floor panels closed.
PO 00000
Frm 00005
Fmt 4702
Sfmt 4702
25.811(f).
5. A portable oxygen bottle must be
present in the lift and easily accessible
to the occupant.
6. Occupancy of the lift must be
limited to a single occupant secured in
one of two possible configurations:
a. The occupant must be secured to a
medical stretcher that is attached to the
lift platform. The occupied stretcher
must be designed to withstand the nonemergency load conditions defined in
loads report SIE–327–301, revision D.
b. The occupant must be secured to a
wheelchair that is attached to the lift
platform.
7. Control panels must be located on
both main and upper decks, connected
with full duplex audio communications.
On both operator control units, an
emergency shut-off switch must be
installed. In an emergency, this switch
must immediately interrupt the main
power supply to the motors. Lift
operation must be stopped until the
emergency shut-off switch is reset. As
soon as one of the operators commands
operation in a direction, the ‘‘Up’’ and
‘‘Down’’ option buttons must be disabled
and the stop button enabled. Before one
of the operators is able to change the
lift-travel direction again, the lift must
first be stopped.
8. Lift operation must require a
trained operator at the main-deck
control panel and a trained observer at
the upper-deck control panel.
9. Sensors must be installed to detect
the following conditions, and to prevent
the start or continuation of lift travel if
any conditions are not met:
a. Upper-deck seat, located on the left
side of the aircraft and just forward of
the master-bath bulkhead, is in its most
forward, outboard position.
b. Upper-deck master-bedroom/
lavatory port bulkhead is opened and
secured.
c. Upper-deck shower door is closed
and secured.
d. Upper-deck master-lavatory door is
opened and secured.
e. Upper-deck floor panels are opened
and configured to form the protective
fencing.
f. Main-deck inboard doors are closed
and secured. The doors must be
lockable only from the outside of the
lift. This ensures that the operator has
control of this area and that nobody is
located under the lift.
g. Aircraft seat-belt-fasten signs must
not be illuminated.
10. Sensors must be installed to detect
the following conditions during

operation, and to prevent continued lift
travel if any of these conditions occur:
a. Over-temperature of lift motors
and/or power-frequency converter.
b. Presence of smoke at motors and in
electrical-control cabinet.
c. Over-current at the lift motors.
d. Asynchronous operation of the
spindles.
11. A built-in fire extinguisher must
be installed in the motor and electricalcontrol cabinet. This fire extinguisher
must be designed to discharge
automatically upon the occurrence of a
fire.
12. The lift must have the provision
for manual operation in the event of a
malfunction such as a loss of power to
the lift and/or associated systems.
13. A separate battery backup system
must provide lighting for the lift-control
system, lift control/sensors,
communication system, and lift lights
for a minimum of 10 minutes in the
event of loss of power to the lift and/or
associated systems.
14. Lift placards must be installed
near or adjacent the control panels
identified in special condition 7. The
placards must be stated as follows:
a. THIS LIFT IS APPROVED FOR
MOVING ONLY A SINGLE OCCUPANT
BETWEEN THE MAIN AND UPPER
DECKS AND ONLY WHEN SECURED
TO EITHER AN APPROVED MEDICAL
STRETCHER OR WHEELCHAIR. NO
OTHER USES OF THIS LIFT ARE
APPROVED.
b. DO NOT OPERATE LIFT DURING
TAXI, TAKEOFF, LANDING, OR
TURBULENCE.
c. AN APPROVED MEDICAL
STRETCHER OR WHEELCHAIR MUST
BE PROPERLY SECURED TO THE LIFT
PLATFORM BEFORE OPERATING
THIS LIFT.
d. THE LIFT MUST BE STOWED FOR
TAXI, TAKEOFF, AND LANDING. THE
STOWED POSITION REQUIRES THE
LIFT PLATFORM POSITIONED AT
THE MAIN–DECK LEVEL WITH THE
FLOOR PANELS CLOSED.
15. Instructions on how to:
a. Configure the lift for operation.
b. Operate the lift.
c. Stow the lift for non-operation such
as during TTL and turbulence.
d. Operate the mechanical-override
features in the event of a malfunction
such as a loss of power to the lift and/
or associated systems.
16. Training and related manuals

AGENCY: Federal Aviation

ACTION: Notice of proposed rulemaking
(NPRM).
SUMMARY: We propose to adopt a new
airworthiness directive (AD) for the
products listed above. This proposed
AD results from mandatory continuing
airworthiness information (MCAI)
originated by an aviation authority of
another country to identify and correct
an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as:
Several cases have been reported of cracks
in the joint extrusions securing the outer
bondment to the acoustic panel of the nacelle
transcowl assemblies. Although there is no
effect on flight safety (thrust reverser
stowed), thrust reverser deployment under
rejected take-off or emergency landing load
conditions could potentially result in
acoustic panel failure and possible runway
debris.
*
*
*
*
*
The loss of an acoustic panel during
rejected take-off or emergency landing
load conditions could leave debris on
the runway. This debris, if not removed,
creates an unsafe condition for other
airplanes during take-off or landing, as
those airplanes could impact debris on
the runway and sustain damage. The
proposed AD would require actions that
are intended to address the unsafe
condition described in the MCAI.
DATES: We must receive comments on
this proposed AD by July 2, 2010.

Background
On March 2, 2007, Jet Aviation Engineering Services L.P. (JAES), of
Teterboro, New Jersey, applied for a supplemental type certificate for
a reconfiguration of an aircraft interior in a 747-468. The Boeing
Model 747-468 airplane is FAA approved under Type Certificate A20WE as
a large transport-category airplane that is limited to 660 passengers
or fewer, depending on the interior configuration.
This modification includes the installation of a medical lift
between the main deck and upper deck. The lift allows the transport of
a single occupant between the decks during cruise or ramp operations.
The applicable airworthiness regulations do not contain adequate or
appropriate safety standards for this design feature.
Type Certification Basis
Under the provisions of Title 14, Code of Federal Regulations (14
CFR) 21.101, JAES must show that the 747-468, as changed, continues to
meet the applicable provisions of the regulations incorporated by
reference in Type Certificate A20WE, or of 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 A20WE are as follows:
Part 36, as amended by Amendments 36-1 through 36-15, and
any later amendments in existence at the time of certification.
Special Federal Aviation Regulation (SFAR) 27, as amended
by Amendments 27-1 through 27-6 and any later amendments in existence
at the time of type certification.
Part 25, effective February 1, 1965, as amended by
Amendments 25-1 through 25-59, and the part 25 section-number
exceptions itemized in Type Certificate A20WE.
The following special conditions, exemptions, and equivalent safety
findings, which are part of the Model 747-300 certification basis, are
also part of the certification basis for the Model 747-400.
The special conditions include those enclosed with an FAA letter to
The Boeing Company dated February 20, 1970, and the following:
1. Special Condition 4A, revised to apply to airplanes with the
landing-gear load-evener system deleted, was recorded as an enclosure
to an FAA letter to The Boeing Company dated May 12, 1971.
2. Special Condition No. 25-61-NW-1, for occupancy not to exceed 32
passengers on the upper deck of airplanes with a spiral staircase, was
transmitted to The Boeing Company by FAA letter dated February 26,
1975.
3. Special Condition No. 25-71-NW-3, for occupancy not to exceed 45
passengers on the upper deck of airplanes with a straight-segmented
stairway, was transmitted to The Boeing Company by FAA letter dated
September 8, 1976.
4. Modification of Special Condition No. 25-71-NW-3, for occupancy
not to exceed 110 passengers on the upper deck of airplanes with a
straight-segmented stairway, was transmitted to The Boeing Company by
FAA letter dated August 3, 1981.
5. Special Condition No. 25-77-NW-4, modification of the autopilot
system to approve the airplane for use of the system under Category
IlIb landing conditions, was transmitted to The Boeing Company by FAA
letter dated July 8, 1977.
6. Special Condition No. 25-ANM-16, for use of an overhead crew-
rest area, occupancy not to exceed ten crewmembers, was transmitted to
The Boeing Company by FAA letter dated November 19, 1987. The FAA-
approved procedures required for compliance with paragraph 13 of the
special condition are located in Boeing Document D926U303, Appendix D.
7. Special Condition No. 25-ANM-24, applicable to flight-deck
displays and propulsion-control systems, was provided to Boeing on
December 22, 1988.
8. Special Condition No. 25-ANM-25, which established lightning-and
radio- frequency-energy protection requirements, was provided to Boeing
on December 22, 1988.
Exemptions From Part 25
Exemption no. 1013A, dated December 24, 1969: Exemption from
Section 25.471(b) to allow lateral displacement of the center of
gravity from the airplane centerline.
The following optional requirements, which are part of the Model
747-300 certification basis, apply also to the 747-400:

Emergency-locator transmitter (ELT)........... 25.1415(d).
[[Page 27664]]
Emergency-exit marking........................ 25.811(f).
----------------------------------------------------------------------------------------------------------------
If the Administrator finds that the applicable airworthiness
regulations (i.e., 14 CFR part 25) do not contain adequate or
appropriate safety standards for the 747-468 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 747-468 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.
The FAA issues special conditions, as defined in 14 CFR 11.19, in
accordance with Sec. 11.38, and they become part of the type-
certification basis under 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 or similar novel or unusual design
feature, the special conditions would also apply to the other model
under Sec. 21.101.
Novel or Unusual Design Features
The original aircraft configuration included a straight stairway
between the main deck and upper deck at FS 870. The stairway is
relocated in the new configuration, and the existing stairway is
replaced with an electrically powered medical lift using the opening in
the upper deck formerly occupied by the stairs. When the lift is not in
operation, the upper-deck opening is covered by floor panels. These
floor panels are opened up prior to operation of the lift and form a
protective fencing around the upper-deck opening.
The purpose of the medical lift is to move an occupant between the
master lounge in the upper deck and the medical room on the lower deck.
The lift platform is driven by two redundant electrical motors,
mounted to the rear wall, between the struts. A lifting gear-drive with
shafts and gear boxes is powered on the front and rear of the lift
platform. The spindles are supported at the lifting gear on the lower
support structure and with a strut support on the upper deck. The lift
platform is guided in lateral directions with the guiding rails mounted
on the struts.
Discussion
Due to the novel or unusual features associated with the
installation of this medical lift, the following special conditions are
considered necessary to provide a level of safety equal to that
established by the airworthiness regulations incorporated by reference
in the type-certificate.
Applicability
As discussed above, these special conditions are applicable to the
747-468. Should JAES apply at a later date for a supplemental type
certificate to modify any other model included on Type Certificate
A20WE, to incorporate the same novel or unusual design feature, the
special conditions would apply to that model as well.
Conclusion
This action affects only certain novel or unusual design features
on one model of airplanes. It is not a rule of general applicability
and it affects only the applicant who applied to the FAA for approval
of these features on the airplane.
List of Subjects in 14 CFR Part 25
Aircraft, Aviation safety, Reporting and recordkeeping
requirements.
The authority citation for these special conditions is as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701, 44702, 44704.
The Proposed Special Conditions
Accordingly, the Federal Aviation Administration (FAA) proposes the
following special conditions as part of the type-certification basis
for Boeing 747-468 airplanes modified by JAES.
1. A functional verification must be conducted to ensure the
adequacy of the lift design features that are supposed to prevent
injury to the lift occupant, lift operator, and lift observer.
2. The occupied lift must be designed to withstand the non-
emergency load conditions imposed by the aircraft according to loads
report SIE-327-301, revision D.
3. Occupancy or operation of the lift must not be permitted during
taxi, takeoff, landing (TTL), or turbulent conditions.
4. The lift must be stowed for TTL. The stowed position requires
the lift platform positioned at the main-deck level with the floor
panels closed.
5. A portable oxygen bottle must be present in the lift and easily
accessible to the occupant.
6. Occupancy of the lift must be limited to a single occupant
secured in one of two possible configurations:
a. The occupant must be secured to a medical stretcher that is
attached to the lift platform. The occupied stretcher must be designed
to withstand the non-emergency load conditions defined in loads report
SIE-327-301, revision D.
b. The occupant must be secured to a wheelchair that is attached to
the lift platform.
7. Control panels must be located on both main and upper decks,
connected with full duplex audio communications. On both operator
control units, an emergency shut-off switch must be installed. In an
emergency, this switch must immediately interrupt the main power supply
to the motors. Lift operation must be stopped until the emergency shut-
off switch is reset. As soon as one of the operators commands operation
in a direction, the ``Up'' and ``Down'' option buttons must be disabled
and the stop button enabled. Before one of the operators is able to
change the lift-travel direction again, the lift must first be stopped.
8. Lift operation must require a trained operator at the main-deck
control panel and a trained observer at the upper-deck control panel.
9. Sensors must be installed to detect the following conditions,
and to prevent the start or continuation of lift travel if any
conditions are not met:
a. Upper-deck seat, located on the left side of the aircraft and
just forward of the master-bath bulkhead, is in its most forward,
outboard position.
b. Upper-deck master-bedroom/lavatory port bulkhead is opened and
secured.
c. Upper-deck shower door is closed and secured.
d. Upper-deck master-lavatory door is opened and secured.
e. Upper-deck floor panels are opened and configured to form the
protective fencing.
f. Main-deck inboard doors are closed and secured. The doors must
be lockable only from the outside of the lift. This ensures that the
operator has control of this area and that nobody is located under the
lift.
g. Aircraft seat-belt-fasten signs must not be illuminated.
10. Sensors must be installed to detect the following conditions
during
[[Page 27665]]
operation, and to prevent continued lift travel if any of these
conditions occur:
a. Over-temperature of lift motors and/or power-frequency
converter.
b. Presence of smoke at motors and in electrical-control cabinet.
c. Over-current at the lift motors.
d. Asynchronous operation of the spindles.
11. A built-in fire extinguisher must be installed in the motor and
electrical-control cabinet. This fire extinguisher must be designed to
discharge automatically upon the occurrence of a fire.
12. The lift must have the provision for manual operation in the
event of a malfunction such as a loss of power to the lift and/or
associated systems.
13. A separate battery backup system must provide lighting for the
lift-control system, lift control/sensors, communication system, and
lift lights for a minimum of 10 minutes in the event of loss of power
to the lift and/or associated systems.
14. Lift placards must be installed near or adjacent the control
panels identified in special condition 7. The placards must be stated
as follows:
a. THIS LIFT IS APPROVED FOR MOVING ONLY A SINGLE OCCUPANT BETWEEN
THE MAIN AND UPPER DECKS AND ONLY WHEN SECURED TO EITHER AN APPROVED
MEDICAL STRETCHER OR WHEELCHAIR. NO OTHER USES OF THIS LIFT ARE
APPROVED.
b. DO NOT OPERATE LIFT DURING TAXI, TAKEOFF, LANDING, OR
TURBULENCE.
c. AN APPROVED MEDICAL STRETCHER OR WHEELCHAIR MUST BE PROPERLY
SECURED TO THE LIFT PLATFORM BEFORE OPERATING THIS LIFT.
d. THE LIFT MUST BE STOWED FOR TAXI, TAKEOFF, AND LANDING. THE
STOWED POSITION REQUIRES THE LIFT PLATFORM POSITIONED AT THE MAIN-DECK
LEVEL WITH THE FLOOR PANELS CLOSED.
15. Instructions on how to:
a. Configure the lift for operation.
b. Operate the lift.
c. Stow the lift for non-operation such as during TTL and
turbulence.
d. Operate the mechanical-override features in the event of a
malfunction such as a loss of power to the lift and/or associated
systems.
16. Training and related manuals must include:
a. Limitations and procedures for normal lift operation.
b. Backup and override procedure for evacuating the lift and
returning it to TTL configuration.
17. Special conditions nos. 3. 4, and 14 must be documented in the
Limitations section of the AFM.
