Proposed Revisions to Advisory Circular--Flight Test Guide for 
Certification of Transport Category Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of proposed advisory circular and request for comments.

-----------------------------------------------------------------------

SUMMARY: This notice announces the availability of and requests 
comments regarding proposed revisions to Advisory Circular (AC) 25-7, 
``Flight Test Guide for Certification of Transport Category 
Airplanes.'' AC 25-7 provides guidance on acceptable means, but not the 
only means, of demonstrating compliance with the airworthiness 
standards for transport category airplanes. The proposed revisions 
complement revisions to the airworthiness standards that are being 
proposed by a separate notice. This notice provides interested persons 
an opportunity to comment on the proposed revisions to the AC.

DATES: Comments must be received on or before July 21, 1994.

ADDRESSES: Send all comments on the proposed AC revisions to the 
Federal Aviation Administration, Attention: Don Stimson, Flight Test 
and Systems Branch, ANM-111, Transport Airplane Directorate, Aircraft 
Certification Service, 1601 Lind Ave SW., Renton, WA 98055-4056. 
Comments may be examined at the above address between 7:30 a.m. and 4 
p.m. weekdays, except Federal holidays.

FOR FURTHER INFORMATION CONTACT: Patricia Siegrist, Regulations Branch, 
ANM-114, at the above address, telephone (206) 227-2126.

SUPPLEMENTARY INFORMATION:

Comments Invited

    A copy of the subject AC may be obtained by contacting the person 
named above under FOR FURTHER INFORMATION CONTACT. Interested persons 
are invited to comment on the proposed revisions to the AC by 
submitting such written data, reviews, or arguments as they may desire. 
Commenters must identify the title of the AC and submit comments in 
duplicate to the address specified above. All comments received on or 
before the closing date for comments will be considered by the 
Transport Standards Staff before issuing the final revised AC.

Discussion

    On May 22, 1990, the Aerospace Industries Association of America, 
Inc. (AIA) and the Association Europeene des Constructeurs de Material 
Aerospatial (AECMA) jointly petitioned the FAA and the European Joint 
Aviation Authorities (JAA) to harmonize certain airworthiness 
requirements that apply to transport category airplanes. In their 
petition, a summary of which was published in the July 17, 1990, 
edition of the Federal Register (55 FR 137), AIA and AECMA also 
recommended changes to Advisory Circular (AC) 25-7, ``Flight Test Guide 
for certification of Transport Category Airplanes,'' to ensure that the 
harmonized standards would be interpreted and applied consistently.
    Part 25 of the Federal Aviation Regulations (FAR) prescribes the 
United States airworthiness standards for transport category airplanes. 
Advisory Circular (AC) 25-7 provides guidelines that the FAA has found 
acceptable for flight testing transport category airplanes to 
demonstrate compliance with those airworthiness standards. Revisions to 
part 25, in response to the AIA/AECMA petition, are being proposed by 
the FAA in a notice of proposed rulemaking published elsewhere in this 
issue of the Federal Register. That notice also describes the use of 
the Aviation Rulemaking Advisory Committee (ARAC) to develop both the 
proposed revisions to part 25 and the proposed revisions to AC 25-7.
    The proposed revisions to AC 25-7 provide additional guidance 
material and one means, but not the only means, of complying with the 
part 25 revisions proposed in Notice No. 94-15 entitled, ``Revision of 
Certain Flight Airworthiness Standards to Harmonize with European 
Airworthiness Standards for Transport Category Airplanes,'' published 
in this same edition of the Federal Register. Issuance of the revised 
AC is contingent on final adoption of the proposed revisions to part 
25.

    Issued in Renton, Washington, DC on April 6, 1994.
