Background Airbus applied for FAA certification/ validation of the provisionally designated Model A3XX–100 in its letter AI/L 810.0223/98, dated August 12, 1998, to the FAA. Application for certification by the Joint Aviation Authorities (JAA) of Europe had been made on January 16, 1998, reference AI/ L 810.0019/98. In its letter to the FAA, Airbus requested an extension to the 5year period for type certification in accordance with 14 CFR 21.17(c). The request was for an extension to a 7-year period, using the date of the initial application letter to the JAA as the reference date. The reason given by Airbus for the request for extension is related to the technical challenges, complexity, and the number of new and novel features on the airplane. On November 12, 1998, the Manager, Aircraft Engineering Division, AIR–100, granted Airbus’ request for the 7-year period, based on the date of application to the JAA. In its letter AI/LE-A 828.0040/99 Issue 3, dated July 20, 2001, Airbus stated that its target date for type certification of E:\FR\FM\09AUP1.SGM 09AUP1 Federal Register / Vol. 70, No. 152 / Tuesday, August 9, 2005 / Proposed Rules the Model A380–800 has been moved from May 2005, to January 2006, to match the delivery date of the first production airplane. In accordance with 14 CFR 21.17(d)(2), Airbus chose a new application date of April 20, 1999, and requested that the 7-year certification period which had already been approved be continued. The part 25 certification basis for the Model A380– 800 airplane was adjusted to reflect the new application date. The Model A380–800 airplane will be an all-new, four-engine jet transport airplane with a full double-deck, twoaisle cabin. The maximum takeoff weight will be 1.235 million pounds with a typical three-class layout of 555 passengers. Type Certification Basis Under the provisions of 14 CFR 21.17, Airbus must show that the Model A380– 800 airplane meets the applicable provisions of 14 CFR part 25, as amended by Amendments 25–1 through 25–98. If the Administrator finds that the applicable airworthiness regulations do not contain adequate or appropriate safety standards for the Airbus A380– 800 airplane because of novel or unusual design features, special conditions are prescribed under the provisions of 14 CFR 21.16. In addition to the applicable airworthiness regulations and special conditions, the Airbus Model A380–800 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. In addition, the FAA must issue a finding of regulatory adequacy pursuant to section 611 of Public Law 93–574, the ‘‘Noise Control Act of 1972.’’ Special conditions, as defined in 14 CFR 11.19, are issued in accordance with 14 CFR 11.38 and become part of the type certification basis in accordance with 14 CFR 21.17(a)(2), Amendment 21–69, effective September 16, 1991. 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 features, the special conditions would also apply to the other model under the provisions of 14 CFR 21.101(a)(1), Amendment 21–69, effective September 16, 1991. VerDate jul<14>2003 15:10 Aug 08, 2005 Jkt 205001 Discussion of Novel or Unusual Design Features Emergency evacuations are generally associated with adverse conditions, such as a fire outside the airplane. Because those adverse conditions may pose an immediate threat to the occupants of the airplane, it is often necessary to avoid opening emergency exits that would otherwise be usable. For this reason, it would be extremely useful to have a viewing window or other means of assessing the outside conditions to determine whether to open a particular emergency exit. The regulations governing the certification of the A380 do not adequately address a full-length double deck airplane in terms of the exit of passengers in an emergency and a viewing window or other means of assessing the outside conditions to determine whether to open an emergency exit. Therefore, the FAA is proposing special conditions to ensure that each emergency exit has a means to permit viewing of the conditions outside the exit when the exit is closed. These special conditions are based upon Notice of Proposed Rulemaking (NPRM) 96–9 and Amendment 25–116, effective November 26, 2004, which adopted a similar requirement into § 25.809(a). Applicability As discussed above, these special conditions are applicable to the Airbus A380–800 airplane. Should Airbus 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 under the provisions of § 21.101(a)(1), Amendment 21–69, effective September 16, 1991. Conclusion This action affects only certain novel or unusual design features of the Airbus A380–800 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.

Background

    Airbus applied for FAA certification/validation of the 
provisionally designated Model A3XX-100 in its letter AI/L 810.0223/98, 
dated August 12, 1998, to the FAA. Application for certification by the 
Joint Aviation Authorities (JAA) of Europe had been made on January 16, 
1998, reference AI/L 810.0019/98. In its letter to the FAA, Airbus 
requested an extension to the 5-year period for type certification in 
accordance with 14 CFR 21.17(c). The request was for an extension to a 
7-year period, using the date of the initial application letter to the 
JAA as the reference date. The reason given by Airbus for the request 
for extension is related to the technical challenges, complexity, and 
the number of new and novel features on the airplane. On November 12, 
1998, the Manager, Aircraft Engineering Division, AIR-100, granted 
Airbus' request for the 7-year period, based on the date of application 
to the JAA.
    In its letter AI/LE-A 828.0040/99 Issue 3, dated July 20, 2001, 
Airbus stated that its target date for type certification of

[[Page 46113]]

the Model A380-800 has been moved from May 2005, to January 2006, to 
match the delivery date of the first production airplane. In accordance 
with 14 CFR 21.17(d)(2), Airbus chose a new application date of April 
20, 1999, and requested that the 7-year certification period which had 
already been approved be continued. The part 25 certification basis for 
the Model A380-800 airplane was adjusted to reflect the new application 
date.
    The Model A380-800 airplane will be an all-new, four-engine jet 
transport airplane with a full double-deck, two-aisle cabin. The 
maximum takeoff weight will be 1.235 million pounds with a typical 
three-class layout of 555 passengers.

Type Certification Basis

    Under the provisions of 14 CFR 21.17, Airbus must show that the 
Model A380-800 airplane meets the applicable provisions of 14 CFR part 
25, as amended by Amendments 25-1 through 25-98. If the Administrator 
finds that the applicable airworthiness regulations do not contain 
adequate or appropriate safety standards for the Airbus A380-800 
airplane because of novel or unusual design features, special 
conditions are prescribed under the provisions of 14 CFR 21.16.
    In addition to the applicable airworthiness regulations and special 
conditions, the Airbus Model A380-800 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. In addition, the 
FAA must issue a finding of regulatory adequacy pursuant to section 611 
of Public Law 93-574, the ``Noise Control Act of 1972.''
    Special conditions, as defined in 14 CFR 11.19, are issued in 
accordance with 14 CFR 11.38 and become part of the type certification 
basis in accordance with 14 CFR 21.17(a)(2), Amendment 21-69, effective 
September 16, 1991.
    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 features, the special conditions would also apply to the 
other model under the provisions of 14 CFR 21.101(a)(1), Amendment 21-
69, effective September 16, 1991.

Discussion of Novel or Unusual Design Features

    Emergency evacuations are generally associated with adverse 
conditions, such as a fire outside the airplane. Because those adverse 
conditions may pose an immediate threat to the occupants of the 
airplane, it is often necessary to avoid opening emergency exits that 
would otherwise be usable. For this reason, it would be extremely 
useful to have a viewing window or other means of assessing the outside 
conditions to determine whether to open a particular emergency exit.
    The regulations governing the certification of the A380 do not 
adequately address a full-length double deck airplane in terms of the 
exit of passengers in an emergency and a viewing window or other means 
of assessing the outside conditions to determine whether to open an 
emergency exit. Therefore, the FAA is proposing special conditions to 
ensure that each emergency exit has a means to permit viewing of the 
conditions outside the exit when the exit is closed. These special 
conditions are based upon Notice of Proposed Rulemaking (NPRM) 96-9 and 
Amendment 25-116, effective November 26, 2004, which adopted a similar 
requirement into Sec.  25.809(a).

Applicability

    As discussed above, these special conditions are applicable to the 
Airbus A380-800 airplane. Should Airbus 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 under the provisions of Sec.  
21.101(a)(1), Amendment 21-69, effective September 16, 1991.

Conclusion

    This action affects only certain novel or unusual design features 
of the Airbus A380-800 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.

The Proposed Special Conditions

    Accordingly, pursuant to the authority delegated to me by the 
Administrator, the Federal Aviation Administration (FAA) proposes the 
following special conditions as part of the type certification basis 
for the Airbus A380-800 airplane.
    In addition to the requirements of Sec.  25.809(a), the following 
special conditions apply:
    Each emergency exit must have means to permit viewing of the 
conditions outside the exit when the exit is closed. The viewing means 
may be on the exit or adjacent to it, provided that no obstructions 
exist between the exit and the viewing means. Means must also be 
provided to permit viewing of the likely areas of evacuee ground 
contact with the landing gear extended as well as in all conditions of 
landing gear collapse. A single device that satisfies both objectives 
is acceptable.
