FOR FURTHER INFORMATION CONTACT:
The
substance of these special conditions
has been subject to the notice and
comment period in several prior
instances and has been derived without
substantive change from those
previously issued. It is unlikely that
prior public comment would result in a
significant change from the substance
contained herein. Therefore, because a
delay would significantly affect the
certification of the airplane, the FAA
has determined that prior public notice
and comment are unnecessary and
impracticable.
In addition, since the substance of
these special conditions has been
subject to the public comment process
in several prior instances with no
substantive comments received, the
FAA finds it unnecessary to delay the
effective date and finds that good cause
exists for adopting these special
conditions upon publication in the
Federal Register.

conditions based on the comments we
receive.
Background
On December 19, 2014, Boeing
applied for a type certificate design
change to Type Certificate (TC) No.
T00001SE to install high-wall suites in
the passenger compartment of Boeing
Model 777–300ER airplanes.
The Model 777 series airplane is a
swept-wing, conventional-tail, twinengine, turbofan- powered, transportcategory airplane. The airplane has
seating for 365 passengers and a
maximum takeoff weight of 775,000
pounds.
Type Certification Basis
Under the provisions of title 14, Code
of Federal Regulations (14 CFR) 21.101,
Boeing must show that the Model 777–
300ER airplane, as changed, continues
to meet the applicable provisions of the
regulations listed in Type Certificate No.
T00001SE or the applicable regulations
in effect on the date of application for
the change, except for earlier
amendments as agreed upon by the
FAA.
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 Boeing Model 777–300ER
airplane because of a novel or unusual
design feature, special conditions are
prescribed under the provisions of
§ 21.16.
Special conditions are initially
applicable to the model for which they
are issued. Should the type certificate
for that model be amended later to
include any other model that
incorporates the same novel or unusual
design feature, or should any other
model already included on the same
type certificate be modified to
incorporate the same novel or unusual
design feature, these special conditions
would also apply to the other model
under § 21.101.
In addition to the applicable
airworthiness regulations and special
conditions, the Boeing Model 777–
300ER airplane 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
E:\FR\FM\26OCR1.SGM
26OCR1
Federal Register / Vol. 82, No. 206 / Thursday, October 26, 2017 / Rules and Regulations
the type-certification basis under
§ 21.101.
Novel or Unusual Design Features
The Boeing Model 777–300ER
airplane will incorporate the following
novel or unusual design features:
A passenger cabin with six high-wall
suites arranged in two rows of three
suites each.
Discussion
The Boeing Model 777–300ER
airplane will include, as a customer
option, a passenger cabin with six highwall suites arranged in two rows of
three suites each, in a 1–1–1
configuration. The suites have doors
and walls that are taller than has been
previously certified by the FAA on
Boeing 777 series airplanes. The walls
extend from the floor to the ceiling or
close to the ceiling.
The characteristics of the suite design
are unique such that the suites are not
fully open to the cabin, as are
conventional mini-suites with partialheight surrounds, and they are not
remote from the main cabin, as are
overhead crew rests. Likewise, unique
but suitable fire-protection requirements
for smoke detection and firefighting are
needed for this configuration.
Furthermore, the proposed suite design
necessitates the development of
additional conditions that do not
currently exist within associated
airworthiness standards, including, but
not limited to, alerting and lighting
when oxygen masks are needed, crew
procedures for managing hazards and
suite occupants, and maintaining cabinegress route dimensions after
deformations of the walls and seats.
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.

Applicability
As discussed above, these special
conditions are applicable to the Boeing
Model 777–300ER airplane with highwall, single-occupant suites with doors
installed. Should Boeing apply at a later
date for a change to the type certificate
to include another model incorporating
the same novel or unusual design
feature, these special conditions would
apply to that model as well.
Conclusion
This action affects only certain novel
or unusual design features on one model
series of airplane. It is not a rule of
general applicability.

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 Special Conditions
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 Boeing Model
777–300ER airplanes.
Note: In these special conditions,
‘‘suite’’ means high-wall suite.
1. Where suites are installed, a
supplemental oxygen system must
provide the following:
a. The supplemental oxygen system
for each suite must include a minimum
of two oxygen masks and meet the same
14 CFR part 25 regulations as do the
supplemental oxygen system for the
main passenger-cabin occupants.
b. An aural alert to warn occupants
and to indicate the need to don oxygen
masks in the event of decompression.
The aural alert must activate
concurrently with deployment of the
oxygen masks in the main passenger
cabin.
c. The illumination level of the
normal suite lighting system must be
activated automatically and must be
sufficient for each occupant to locate a
deployed oxygen mask.
d. If a chemical oxygen generator is
used as the oxygen supply source, the
suite oxygen installation must meet
§§ 25.795(d) and 25.1450.
2. A smoke-detection or fire-detection
system (or systems) must be provided
that monitors each occupiable space
within the suite. Flight tests must be
conducted to show compliance with
this requirement. If a fire occurs, each
system (or systems) in the affected suite
must provide:
a. A visual indication to the flight
deck within one minute after the start of
a fire.
b. An aural warning in the suite area
where detection has occurred.
c. A warning in the main passenger
cabin. This warning must be readily
detectable by a flight attendant, taking
into consideration the locations of flight
attendants throughout the main
passenger compartment during various
phases of flight.
3. Passenger-management procedures
must be provided should occupants
need to be moved in the event of smoke
detection, or firefighting within the
suite or where suites are installed:
a. A limitation must be included in
the airplane flight manual (AFM) or
PO 00000
Frm 00009
Fmt 4700
Sfmt 4700
49493
other suitable means requiring that
crewmembers be trained in the suite
passenger-management procedures.
b. Approved procedures describing
methods for suite passenger
management must be established. These
procedures must be transmitted to the
operator for incorporation into its
training programs and appropriate
operational manuals.
4. The design of each suite, and the
location of the firefighting equipment
where suites are installed, must allow
the crewmembers to conduct effective
firefighting in the suite. For a manual,
hand-held extinguishing system
(designed as the sole means to fight a
fire) for the suite:
a. A limitation must be included in
the AFM or other suitable means
requiring that crewmembers be trained
in the firefighting procedures.
b. Each suite design must allow
crewmembers equipped for firefighting
to have unrestricted access to all parts
of the suite compartment.
c. The time for a crewmember in the
main passenger cabin to react to the fire
alarm and gain access to the suite must
not exceed the time it would take for the
compartment to become filled with
smoke, thus making it difficult to locate
the fire source(s).
d. Approved procedures describing
methods for searching the suite
compartment for fire source(s) must be
established. These procedures must be
transmitted to the operator for
incorporation into its training programs
and appropriate operational manuals.
5. A means must be provided to
prevent hazardous quantities of smoke
or extinguishing agent originating in
each suite from entering any other
occupiable compartments.
a. Small quantities of smoke may
penetrate from the suite into other
occupied areas during the one-minute
smoke detection time.
b. Hazardous quantities of smoke may
not enter any occupied compartment
during access to manually fight a fire in
the suite. A small amount of smoke may
enter the occupied compartments while
a firefighter enters and exits the suite,
and is not considered hazardous
provided the smoke dissipates quickly.
c. Flight tests must be conducted to
show compliance with this requirement.
6. If waste-disposal receptacles are
fitted in the suite, the suite must be
equipped with an automatic fireextinguishing system that meets the
performance requirements of
§ 25.854(b).
7. Each stowage compartment in the
suite must be completely enclosed. All
enclosed stowage compartments within
the suite compartment that are not
E:\FR\FM\26OCR1.SGM

Federal Register / Vol. 82, No. 206 / Thursday, October 26, 2017 / Rules and Regulations
limited to stowage of emergency
equipment or airplane- supplied
equipment (i.e., bedding) must meet the
design criteria described in the table
below. Enclosed stowage compartments
greater than 57 feet 3 inches cubic
interior volume are not permitted by
these special conditions.

1 Compliant Materials of Construction: The material used in constructing each enclosed stowage compartment must at least be fire resistant
and must meet the flammability standards established for interior components (i.e., 14 CFR part 25 Appendix F, Parts I, IV, and V) per the requirements of § 25.853. For compartments less than 25 ft.3 in interior volume, the design must ensure the ability to contain a fire likely to occur
within the compartment under normal use.
2 Smoke or Fire Detectors: Enclosed stowage compartments equal to or exceeding 25 ft.3 in interior volume must be provided with a smoke- or
fire-detection system to ensure that a fire can be detected within a one-minute detection time. Flight tests must be conducted to show compliance with this requirement. Each system (or systems) must provide:
b A visual indication in the flight deck within one minute after the start of a fire.
b An aural warning in the suite compartment.
b A warning in the main passenger cabin. This warning must be readily detectable by a flight attendant, taking into consideration the locations
of flight attendants throughout the main passenger compartment during various phases of flight.
3 Liner: If material used in constructing the stowage compartment can be shown to meet the flammability requirements of a liner for a Class B
cargo compartment (i.e., § 25.855 at Amendment 25–116, and Appendix F, part I, paragraph (a)(2)(ii)), then no liner would be required for enclosed stowage compartments equal to or greater than 25 ft.3 but less than 57 ft.3 in interior volume. For all enclosed stowage compartments
equal to 57 ft.3 in interior volume, a liner must be provided that meets the requirements of § 25.855 for a Class B cargo compartment.
4 Fire Location Detector: If a suite compartment has enclosed stowage compartments exceeding 25 ft.3 interior volume that are located separately from the other stowage compartments (located, for example, away from one central location, such as the entry to the suite compartment or
a common area within the suite compartment, where the other stowage compartments are), that suite compartment would require additional fireprotection features and/or devices to assist the firefighter in determining the location of a fire.
8. Where suites are installed, the
design of each suite must:
a. Maintain minimum main aisle(s),
cross aisle(s), and passageway(s)
requirements of § 25.815 when
subjected to the ultimate inertia forces
listed in § 25.561(d).
b. Prevent structural failure or
deformation of components that could
block access to the available evacuation
routes (e.g., seats, doors, contents of
stowage compartments, etc.).
9. In addition to the requirements of
§ 25.562 for seat systems, which are
occupiable during taxi, takeoff, and
landing, the suite structure must be
designed for the additional loads
imposed by the seats as a result of the
conditions specified in § 25.562(b).

Background
On December 19, 2014, Boeing applied for a type certificate design
change to Type Certificate (TC) No. T00001SE to install high-wall
suites in the passenger compartment of Boeing Model 777-300ER
airplanes.
The Model 777 series airplane is a swept-wing, conventional-tail,
twin-engine, turbofan- powered, transport-category airplane. The
airplane has seating for 365 passengers and a maximum takeoff weight of
775,000 pounds.
Type Certification Basis
Under the provisions of title 14, Code of Federal Regulations (14
CFR) 21.101, Boeing must show that the Model 777-300ER airplane, as
changed, continues to meet the applicable provisions of the regulations
listed in Type Certificate No. T00001SE or the applicable regulations
in effect on the date of application for the change, except for earlier
amendments as agreed upon by the FAA.
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 Boeing Model 777-300ER airplane
because of a novel or unusual design feature, special conditions are
prescribed under the provisions of Sec. 21.16.
Special conditions are initially applicable to the model for which
they are issued. Should the type certificate for that model be amended
later to include any other model that incorporates the same novel or
unusual design feature, or should any other model already included on
the same type certificate be modified to incorporate the same novel or
unusual design feature, these special conditions would also apply to
the other model under Sec. 21.101.
In addition to the applicable airworthiness regulations and special
conditions, the Boeing Model 777-300ER airplane 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
[[Page 49493]]
the type-certification basis under Sec. 21.101.
Novel or Unusual Design Features
The Boeing Model 777-300ER airplane will incorporate the following
novel or unusual design features:
A passenger cabin with six high-wall suites arranged in two rows of
three suites each.
Discussion
The Boeing Model 777-300ER airplane will include, as a customer
option, a passenger cabin with six high-wall suites arranged in two
rows of three suites each, in a 1-1-1 configuration. The suites have
doors and walls that are taller than has been previously certified by
the FAA on Boeing 777 series airplanes. The walls extend from the floor
to the ceiling or close to the ceiling.
The characteristics of the suite design are unique such that the
suites are not fully open to the cabin, as are conventional mini-suites
with partial-height surrounds, and they are not remote from the main
cabin, as are overhead crew rests. Likewise, unique but suitable fire-
protection requirements for smoke detection and firefighting are needed
for this configuration. Furthermore, the proposed suite design
necessitates the development of additional conditions that do not
currently exist within associated airworthiness standards, including,
but not limited to, alerting and lighting when oxygen masks are needed,
crew procedures for managing hazards and suite occupants, and
maintaining cabin-egress route dimensions after deformations of the
walls and seats.
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.
Applicability
As discussed above, these special conditions are applicable to the
Boeing Model 777-300ER airplane with high-wall, single-occupant suites
with doors installed. Should Boeing apply at a later date for a change
to the type certificate to include another model incorporating the same
novel or unusual design feature, these special conditions would apply
to that model as well.
Conclusion
This action affects only certain novel or unusual design features
on one model series of airplane. It is not a rule of general
applicability.
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 Special Conditions
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 Boeing Model 777-300ER airplanes.
Note: In these special conditions, ``suite'' means high-wall suite.
1. Where suites are installed, a supplemental oxygen system must
provide the following:
a. The supplemental oxygen system for each suite must include a
minimum of two oxygen masks and meet the same 14 CFR part 25
regulations as do the supplemental oxygen system for the main
passenger-cabin occupants.
b. An aural alert to warn occupants and to indicate the need to don
oxygen masks in the event of decompression. The aural alert must
activate concurrently with deployment of the oxygen masks in the main
passenger cabin.
c. The illumination level of the normal suite lighting system must
be activated automatically and must be sufficient for each occupant to
locate a deployed oxygen mask.
d. If a chemical oxygen generator is used as the oxygen supply
source, the suite oxygen installation must meet Sec. Sec. 25.795(d)
and 25.1450.
2. A smoke-detection or fire-detection system (or systems) must be
provided that monitors each occupiable space within the suite. Flight
tests must be conducted to show compliance with this requirement. If a
fire occurs, each system (or systems) in the affected suite must
provide:
a. A visual indication to the flight deck within one minute after
the start of a fire.
b. An aural warning in the suite area where detection has occurred.
c. A warning in the main passenger cabin. This warning must be
readily detectable by a flight attendant, taking into consideration the
locations of flight attendants throughout the main passenger
compartment during various phases of flight.
3. Passenger-management procedures must be provided should
occupants need to be moved in the event of smoke detection, or
firefighting within the suite or where suites are installed:
a. A limitation must be included in the airplane flight manual
(AFM) or other suitable means requiring that crewmembers be trained in
the suite passenger-management procedures.
b. Approved procedures describing methods for suite passenger
management must be established. These procedures must be transmitted to
the operator for incorporation into its training programs and
appropriate operational manuals.
4. The design of each suite, and the location of the firefighting
equipment where suites are installed, must allow the crewmembers to
conduct effective firefighting in the suite. For a manual, hand-held
extinguishing system (designed as the sole means to fight a fire) for
the suite:
a. A limitation must be included in the AFM or other suitable means
requiring that crewmembers be trained in the firefighting procedures.
b. Each suite design must allow crewmembers equipped for
firefighting to have unrestricted access to all parts of the suite
compartment.
c. The time for a crewmember in the main passenger cabin to react
to the fire alarm and gain access to the suite must not exceed the time
it would take for the compartment to become filled with smoke, thus
making it difficult to locate the fire source(s).
d. Approved procedures describing methods for searching the suite
compartment for fire source(s) must be established. These procedures
must be transmitted to the operator for incorporation into its training
programs and appropriate operational manuals.
5. A means must be provided to prevent hazardous quantities of
smoke or extinguishing agent originating in each suite from entering
any other occupiable compartments.
a. Small quantities of smoke may penetrate from the suite into
other occupied areas during the one-minute smoke detection time.
b. Hazardous quantities of smoke may not enter any occupied
compartment during access to manually fight a fire in the suite. A
small amount of smoke may enter the occupied compartments while a
firefighter enters and exits the suite, and is not considered hazardous
provided the smoke dissipates quickly.
c. Flight tests must be conducted to show compliance with this
requirement.
6. If waste-disposal receptacles are fitted in the suite, the suite
must be equipped with an automatic fire-extinguishing system that meets
the performance requirements of Sec. 25.854(b).
7. Each stowage compartment in the suite must be completely
enclosed. All enclosed stowage compartments within the suite
compartment that are not
[[Page 49494]]
limited to stowage of emergency equipment or airplane- supplied
equipment (i.e., bedding) must meet the design criteria described in
the table below. Enclosed stowage compartments greater than 57 feet 3
inches cubic interior volume are not permitted by these special
conditions.
Design Criteria for Enclosed Stowage Compartments Not Limited to Stowage of Emergency or Airplane-Supplied
Equipment
----------------------------------------------------------------------------------------------------------------
Applicability of fire-protection requirements by interior volume
--------------------------------------------------------------------------
Fire protection features Less than 25 cubic 25 Cubic feet to less
feet than 57 Cubic feet 57 cubic feet
----------------------------------------------------------------------------------------------------------------
Compliant Materials of Construction Yes.................... Yes.................... Yes.
\1\.
Smoke or Fire Detectors \2\.......... No..................... Yes.................... Yes.
Liner \3\............................ No..................... Conditional............ Yes.
Fire Location Detector \4\........... No..................... Yes.................... Yes.
----------------------------------------------------------------------------------------------------------------
\1\ Compliant Materials of Construction: The material used in constructing each enclosed stowage compartment
must at least be fire resistant and must meet the flammability standards established for interior components
(i.e., 14 CFR part 25 Appendix F, Parts I, IV, and V) per the requirements of Sec. 25.853. For compartments
less than 25 ft.3 in interior volume, the design must ensure the ability to contain a fire likely to occur
within the compartment under normal use.
\2\ Smoke or Fire Detectors: Enclosed stowage compartments equal to or exceeding 25 ft.3 in interior volume must
be provided with a smoke- or fire-detection system to ensure that a fire can be detected within a one-minute
detection time. Flight tests must be conducted to show compliance with this requirement. Each system (or
systems) must provide:
[ballot] A visual indication in the flight deck within one minute after the start of a fire.
[ballot] An aural warning in the suite compartment.
[ballot] A warning in the main passenger cabin. This warning must be readily detectable by a flight attendant,
taking into consideration the locations of flight attendants throughout the main passenger compartment during
various phases of flight.
\3\ Liner: If material used in constructing the stowage compartment can be shown to meet the flammability
requirements of a liner for a Class B cargo compartment (i.e., Sec. 25.855 at Amendment 25-116, and Appendix
F, part I, paragraph (a)(2)(ii)), then no liner would be required for enclosed stowage compartments equal to
or greater than 25 ft.3 but less than 57 ft.3 in interior volume. For all enclosed stowage compartments equal
to 57 ft.3 in interior volume, a liner must be provided that meets the requirements of Sec. 25.855 for a
Class B cargo compartment.
\4\ Fire Location Detector: If a suite compartment has enclosed stowage compartments exceeding 25 ft.3 interior
volume that are located separately from the other stowage compartments (located, for example, away from one
central location, such as the entry to the suite compartment or a common area within the suite compartment,
where the other stowage compartments are), that suite compartment would require additional fire-protection
features and/or devices to assist the firefighter in determining the location of a fire.
8. Where suites are installed, the design of each suite must:
a. Maintain minimum main aisle(s), cross aisle(s), and
passageway(s) requirements of Sec. 25.815 when subjected to the
ultimate inertia forces listed in Sec. 25.561(d).
b. Prevent structural failure or deformation of components that
could block access to the available evacuation routes (e.g., seats,
doors, contents of stowage compartments, etc.).
9. In addition to the requirements of Sec. 25.562 for seat
systems, which are occupiable during taxi, takeoff, and landing, the
suite structure must be designed for the additional loads imposed by
the seats as a result of the conditions specified in Sec. 25.562(b).
