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 with an executive cabin interior. 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 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. 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). 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 the provisions of § 21.101. Novel or Unusual Design Features The GVI will have a fly-by-wire electronic flight control system. This system provides an electronic interface between the pilot’s flight controls and E:\FR\FM\13DEP1.SGM 13DEP1 77570 Federal Register / Vol. 75, No. 238 / Monday, December 13, 2010 / Proposed Rules the flight control surfaces for both normal and failure states, and it generates the actual surface commands that provide for stability augmentation and control about all three airplane axes. Because electronic flight control system technology has outpaced existing regulations (primarily §§ 25.671 and 25.672), a special condition is proposed to ensure appropriate mode recognition by the flight crew for events which significantly change the operating mode of the electronic flight control system. Discussion of Proposed Special Conditions Some failures of this system may lead to a degraded operating mode that does not merit a classic ‘‘failure warning’’ but in which flight envelope protection is lost and the flight crew must fly the airplane differently to avoid a stall or to avoid exceeding structural speed limitations. In that case, mode awareness by the flight crew is necessary to avoid confusion and protect safe flight. Therefore, these special conditions for flight control system mode annunciation propose suitable mode annunciation be provided to the flight crew for such events. Applicability As discussed above, these proposed special conditions are applicable to the GVI. Should Gulfstream 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 proposed special conditions would apply to that model as well. Conclusion This action affects only certain novel or unusual design features of the GVI. It is not a rule of general applicability.

SUPPLEMENTARY INFORMATION: Comments Invited Airworthiness Directives; General Electric Company CF6 Series Turbofan Engines Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: The FAA proposes to supersede an existing airworthiness directive (AD) for General Electric (GE) CF6–45/–50 series and CF6–80A series turbofan engines with certain part number (P/N) side links of the five-link forward mount assembly installed. That AD currently requires an initial and repetitive visual inspection of the side links for cracks, and stripping and reapplying the Sermetel W coating on the side link at every exposure of the side link. That AD also requires replacing the side links and pylon attachment bolts, and inspecting the fail-safe bolt and platform lug if the side links are cracked. This proposed AD would continue to require those same inspections and stripping and reapplying the Sermetel W coating, and would add two part numbers to the applicability. This proposed AD results from a review of the inspection program, which revealed that GE had omitted two affected part numbers from the applicability. We are proposing this AD to prevent failure of the side links and possible engine separation from the airplane. DATES: We must receive any comments on this proposed AD by February 11, 2011.

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 with an executive cabin interior. 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 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 Sec.  21.16.
    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 Sec.  11.38, and they become part of the type 
certification basis under Sec.  21.17(a)(2).
    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 the provisions of Sec.  21.101.

Novel or Unusual Design Features

    The GVI will have a fly-by-wire electronic flight control system. 
This system provides an electronic interface between the pilot's flight 
controls and

[[Page 77570]]

the flight control surfaces for both normal and failure states, and it 
generates the actual surface commands that provide for stability 
augmentation and control about all three airplane axes. Because 
electronic flight control system technology has outpaced existing 
regulations (primarily Sec. Sec.  25.671 and 25.672), a special 
condition is proposed to ensure appropriate mode recognition by the 
flight crew for events which significantly change the operating mode of 
the electronic flight control system.

Discussion of Proposed Special Conditions

    Some failures of this system may lead to a degraded operating mode 
that does not merit a classic ``failure warning'' but in which flight 
envelope protection is lost and the flight crew must fly the airplane 
differently to avoid a stall or to avoid exceeding structural speed 
limitations. In that case, mode awareness by the flight crew is 
necessary to avoid confusion and protect safe flight. Therefore, these 
special conditions for flight control system mode annunciation propose 
suitable mode annunciation be provided to the flight crew for such 
events.

Applicability

    As discussed above, these proposed special conditions are 
applicable to the GVI. Should Gulfstream 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 proposed special 
conditions would apply to that model as well.

Conclusion

    This action affects only certain novel or unusual design features 
of the GVI. It is not a rule of general applicability.

    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 the GVI airplanes.

    If the design of the flight control system has multiple modes of 
operation, a means must be provided to indicate to the flight crew 
any mode that significantly changes or degrades the normal handling 
or operational characteristics of the airplane.
