SUMMARY:
On November 4, 2005, The Boeing
Company, PO Box 3707, Seattle, WA,
98124, applied for an amendment to
Type Certificate Number A20WE to

Type Certification Basis
Under the provisions of Title 14, Code
of Federal Regulations (14 CFR) 21.101,
Boeing must show that the Model 747–
8 (hereafter referred as 747–8) meets the
applicable provisions of part 25,
Amendments 25–1 through 25–120,
plus Amendment 25–127 for § 25.795(a),
except for earlier amendments as agreed
upon by the FAA. These regulations
will be incorporated into Type
Certificate No. A20WE after type
certification approval of the 747–8.
In addition, the certification basis
includes other regulations, special
conditions, and exemptions that are not
relevant to these special conditions.
Type Certificate No. A20WE will be
updated to include a complete
description of the certification basis for
these airplanes.
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 747–8 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 or series that
incorporates the same or similar novel
or unusual design feature, or should any
other model or series already included
on the same type certificate be modified
to incorporate the same or similar novel
or unusual design feature, the special
conditions would also apply to the other
model or series under § 21.101.
In addition to the applicable
airworthiness regulations and special
conditions, the 747–8 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
§ 11.19, are issued under § 11.38, and
become part of the type certification
basis under § 21.101.
Novel or Unusual Design Features
The Boeing Model 747–8 will
incorporate the following novel or
unusual design features: The 747–8
design offers seating capacity on two
separate decks, the main deck with a
maximum passenger capacity of 495 and
the upper deck with a maximum
passenger capacity of 110. Occupants
VerDate Mar<15>2010

Jkt 223001
can move between decks via a staircase
located near door 2 on the main deck of
the airplane in the forward part of the
cabin. With large seating capacities on
the main deck and upper deck of the
747–8, the stairway must be designed to
support evacuation between decks of
the airplane in an in-flight emergency.
Discussion
The regulations governing the
certification of the 747–8 do not
adequately address the certification
requirements for a two-deck passenger
airplane. The Airbus A380–800 and all
of the earlier Boeing 747 passenger
airplane models were certified with
seating capacity on two separate decks.
When the seating capacity of the upper
deck of the Boeing 747 exceeded 24
passengers, the FAA issued Special
Condition No. 25–61–NW–1 for a
maximum seat capacity of 32 passengers
on the upper deck for take-off and
landing. A second set of special
conditions, Special Condition No. 25–
71–NW–3, was issued to include
airplanes up to a maximum seating
capacity of 45 passengers on the upper
deck for take-off and landing. The
second set of special conditions was
modified to address airplanes with a
maximum seating capacity of 110
passengers on the upper deck for takeoff and landing. Special Conditions No.
25–326–SC for the Airbus A380–800
allowed a seating capacity on two
separate decks: the main deck with a
maximum passenger capacity of 542 and
the upper deck with a maximum
passenger capacity of 308. Although
these previously issued special
conditions for the A380–800 provided a
starting point for developing the 747–8
special conditions, the 747–8 special
conditions are specific to the unique
aspects of this airplane’s design.
The regulations do not adequately
address a passenger airplane with
separate decks for passenger occupancy,
thus the FAA considers this to be a
novel design. Therefore, the FAA has
determined that special conditions, in
addition to the requirements of
§§ 25.803 and 25.811 through 25.813,
are required to address the proposed
design.
Discussion of Comments
Notice of proposed special conditions
No. 25–11–08–SC for Boeing Model
747–8 airplanes was published in the
Federal Register on March 18, 2011 (76
FR 14819). No comments were received
and the special conditions are adopted
as proposed.

Applicability
As discussed above, these special
conditions are applicable to Boeing
Model 747–8 airplanes. 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 features, these special
conditions would apply to that model as
well.
Conclusion
This action affects only certain novel
or unusual design features of Boeing
Model 747–8 airplanes. It is not a rule
of general applicability.

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
747–8 airplanes.
1. The stairway must have essentially
straight route segments with a landing at
each significant change in segment
direction.
2. The stairway must have essentially
rectangular treads.
3. With the airplane in level attitude
and in each attitude resulting from the
collapse of one or more legs of the
landing gear, the stairway must have
entrance, exit, and gradient
characteristics that allow the upper deck
passengers, with assistance from a
crewmember, to merge with passengers
on the main deck during an emergency
evacuation and exit the airplane through
a main deck exit. This must be shown
by demonstration, tests, analysis, or any
combination thereof.
4. The stairway must accommodate
the carriage of an incapacitated
occupant from the upper deck to the
main deck. The crewmember
procedures for such carriage must be
established and included in the airplane
flight manual.
5. The stairway must be located to
provide occupants an adequate descent
rate under probable emergency
conditions, including a condition in
which an occupant falls or is
incapacitated while on the stairway.
6. The stairway must be designed and
located to minimize damage to its
structure during an emergency landing
or ditching.

7. General illumination must be
provided so, when measured along the
center lines of each tread and landing,
the illumination is not less than 0.05
foot-candle. This is in lieu of
compliance with § 25.812(c), at
Amendment 25–116.
8. Means must be provided to assist
passengers in locating the stairway in
dense smoke conditions as part of
compliance with § 25.811(c), at

§ 25.812(b)(1)(i), at Amendment 25–116,
must be provided in the upper deck
near the stairway visible to passengers
approaching along the main aisle as
required by § 25.811(d)(1), at
Amendment 25–88.
10. Floor proximity lighting required
by § 25.812(e), at Amendment 25–120,
must be provided along the stairs.
11. When passengers occupy the
upper deck, at least one flight attendant
must also be present during taxi, takeoff, and landing.
12. The stairway must have a handrail
on at least one side to allow occupants
to steady themselves during foreseeable
conditions, including but not limited to,
gear collapse on the ground and
moderate turbulence in flight. The
handrail(s) must be constructed so there
is no obstruction on them that will
cause the user to release his/her grip or
hinder the continuous movement of the
hands along the handrail. Handrail(s)
must be terminated in a manner that
will not interfere with occupants
walking by or create a hazard (such as
catching clothing). Boeing must
demonstrate that the design can
accommodate the stature of a fifth
percentile female and a ninety-fifth
percentile male.
13. The public address system must
be intelligible in the stairway during all
flight phases.
14. ‘‘No smoking’’ and ‘‘return to seat’’
signs must be installed and visible in
the stairway both going up and down
and at the stairway entrances.

SUPPLEMENTARY INFORMATION:
SUMMARY:
Background
On March 29, 2005, Gulfstream
Aerospace Corporation (hereafter
referred to as ‘‘Gulfstream’’) applied for
an FAA type certificate for its new
Gulfstream Model GVI passenger
airplane. Gulfstream later applied for,
and was granted, an extension of time
for the type certificate, which changed
the effective application date to
September 28, 2006. The Gulfstream
Model GVI airplane will be an all-new,
two-engine jet transport airplane. The
maximum takeoff weight will be 99,600
pounds, with a maximum passenger
count of 19 passengers.
Type Certification Basis
Under provisions of Title 14, Code of
Federal Regulations (14 CFR) 21.17,
Gulfstream must show that the
Gulfstream Model GVI airplane
(hereafter referred to as ‘‘the GVI’’) meets
the applicable provisions of 14 CFR part
25, as amended by Amendments 25–1
through 25–119, 25–122, and 25–124. If
the Administrator finds that the
PO 00000
Frm 00003
Fmt 4700
Sfmt 4700
31453
applicable airworthiness regulations
(i.e., 14 CFR part 25) do not contain
adequate or appropriate safety standards
for the GVI 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 features, the special conditions
would also apply to the other model
under provisions of § 21.101.
In addition to complying with the
applicable airworthiness regulations
and special conditions, the GVI 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 must also issue a finding of
regulatory adequacy pursuant to section
611 of Public Law 92–574, the ‘‘Noise
Control Act of 1972.’’
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
§ 21.17(a)(2).
Novel or Unusual Design Features
The Gulfstream model GVI airplane
will incorporate the following novel or
unusual design feature: A singleoccupant side-facing seat intended to be
occupied during takeoff and landing.
Discussion
Section 25.785(b), requires that ‘‘each
seat * * * at each station designated as
occupiable during takeoff and landing
must be designed so that a person
making proper use of these facilities
will not suffer serious injury in an
emergency landing as a result of the
inertia forces specified in §§ 25.561 and
25.562.’’ Additionally, § 25.562 requires
dynamic testing of all seats occupied
during takeoff and landing. The relative
forces and injury mechanisms affecting
the occupants of side-facing seats during
an emergency landing are different from
those of standard forward or aft facing
seats. Therefore, the FAA has
determined that, in addition to the
requirements of part 21 and part 25,
these special conditions are needed to
address this seat installation.

SUPPLEMENTARY INFORMATION:
Background
On November 4, 2005, The Boeing Company, PO Box 3707, Seattle, WA,
98124, applied for an amendment to Type Certificate Number A20WE to
include the new Model 747-8 series passenger airplane. The Model 747-8
is a derivative of the 747-400. The Model 747-8 is a four-engine jet
transport
[[Page 31452]]
airplane that will have a maximum takeoff weight of 975,000 pounds, new
General Electric GEnx -2B67 engines, and the capacity to carry 605
passengers.
Type Certification Basis
Under the provisions of Title 14, Code of Federal Regulations (14
CFR) 21.101, Boeing must show that the Model 747-8 (hereafter referred
as 747-8) meets the applicable provisions of part 25, Amendments 25-1
through 25-120, plus Amendment 25-127 for Sec. 25.795(a), except for
earlier amendments as agreed upon by the FAA. These regulations will be
incorporated into Type Certificate No. A20WE after type certification
approval of the 747-8.
In addition, the certification basis includes other regulations,
special conditions, and exemptions that are not relevant to these
special conditions. Type Certificate No. A20WE will be updated to
include a complete description of the certification basis for these
airplanes.
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 747-8 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 or series that incorporates the same
or similar novel or unusual design feature, or should any other model
or series already included on the same type certificate be modified to
incorporate the same or similar novel or unusual design feature, the
special conditions would also apply to the other model or series under
Sec. 21.101.
In addition to the applicable airworthiness regulations and special
conditions, the 747-8 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 Sec. 11.19, are issued under
Sec. 11.38, and become part of the type certification basis under
Sec. 21.101.
Novel or Unusual Design Features
The Boeing Model 747-8 will incorporate the following novel or
unusual design features: The 747-8 design offers seating capacity on
two separate decks, the main deck with a maximum passenger capacity of
495 and the upper deck with a maximum passenger capacity of 110.
Occupants can move between decks via a staircase located near door 2 on
the main deck of the airplane in the forward part of the cabin. With
large seating capacities on the main deck and upper deck of the 747-8,
the stairway must be designed to support evacuation between decks of
the airplane in an in-flight emergency.
Discussion
The regulations governing the certification of the 747-8 do not
adequately address the certification requirements for a two-deck
passenger airplane. The Airbus A380-800 and all of the earlier Boeing
747 passenger airplane models were certified with seating capacity on
two separate decks. When the seating capacity of the upper deck of the
Boeing 747 exceeded 24 passengers, the FAA issued Special Condition No.
25-61-NW-1 for a maximum seat capacity of 32 passengers on the upper
deck for take-off and landing. A second set of special conditions,
Special Condition No. 25-71-NW-3, was issued to include airplanes up to
a maximum seating capacity of 45 passengers on the upper deck for take-
off and landing. The second set of special conditions was modified to
address airplanes with a maximum seating capacity of 110 passengers on
the upper deck for take-off and landing. Special Conditions No. 25-326-
SC for the Airbus A380-800 allowed a seating capacity on two separate
decks: the main deck with a maximum passenger capacity of 542 and the
upper deck with a maximum passenger capacity of 308. Although these
previously issued special conditions for the A380-800 provided a
starting point for developing the 747-8 special conditions, the 747-8
special conditions are specific to the unique aspects of this
airplane's design.
The regulations do not adequately address a passenger airplane with
separate decks for passenger occupancy, thus the FAA considers this to
be a novel design. Therefore, the FAA has determined that special
conditions, in addition to the requirements of Sec. Sec. 25.803 and
25.811 through 25.813, are required to address the proposed design.
Discussion of Comments
Notice of proposed special conditions No. 25-11-08-SC for Boeing
Model 747-8 airplanes was published in the Federal Register on March
18, 2011 (76 FR 14819). No comments were received and the special
conditions are adopted as proposed.
Applicability
As discussed above, these special conditions are applicable to
Boeing Model 747-8 airplanes. 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 features, these special conditions
would apply to that model as well.
Conclusion
This action affects only certain novel or unusual design features
of Boeing Model 747-8 airplanes. It is not a rule of general
applicability.
