DEPARTMENT OF TRANSPORTATION
Federal Aviation Administration
Advisory Circular (AC) 91-60A, the Continued Airworthiness of
Older Airplanes; AC 120-AAR, Aging Airplane Inspections and Records
Review; and AC 91-56B, Continuing Structural Integrity Program for
Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of availability and request for comments.
-----------------------------------------------------------------------
SUMMARY: This notice announces the availability of and request for
comments on proposed Advisory Circular (AC) 91-60A, which provides
guidance about development and use of service-history based Structural
Supplemental Inspection Programs to design-approval holders, owners,
and operators of U.S.-registered multi-engine airplanes certificated
with nine or less passenger seats; AC 120-AAR, which provides guidance
about aging airplane inspections and records reviews that are
accomplished to satisfy the requirements of the final rule ``Aging
Airplane Safety;'' and AC 91-56B, which provides guidance on developing
a continuing structural integrity program to ensure safe operation of
older airplanes throughout their operational life. These proposed ACs
address airplanes affected by the ``Aging Airplane Safety Rule'' and
provide guidance on the development and use of a damage-tolerance-based
Supplemental Structural Inspection Program (SSIP) for all airplanes
operated under title 14 of the Code of Federal Regulations (14 CFR)
part 121; all U.S.-registered multi-engine airplanes operated under 14
CFR part 129 certificated with 10 or more passenger seats; and all
multiengine airplanes used in scheduled operations under 14 CFR part
135 certificated with 10 or more passenger seats. These ACs outline an
acceptable method, but not the only method, of compliance with the
Aging Airplane Safety Rule.
DATES: Comments must be received on or before December 20, 2002.
ADDRESSES: Send all comments on the proposed ACs to: Brent Bandley,
Transport Airplane Directorate, Los Angeles Aircraft Certification
Office, ANM-120L, Federal Aviation Administration; 3960 Paramount
Boulevard, Lakewood, CA 90712--4137; telephone number: (562) 627-5237,
facsimile: (562) 627-5210.

SUPPLEMENTARY INFORMATION:
Comments Invited
Copies of the draft ACs may be obtained by accessing the FAA's Web
page at http://www.faa.gov/avr/arm/nprm/nprm.htm or at http://faa.gov/
avr/afs/acs/ac-idx.htm. Interested parties are invited to submit
comments on the proposed ACs. Commenters must identify AC 91-60A, AC
120-AAR, or AC 91-56B and submit comments to the address specified
above. The FAA will consider all communications received on or before
the closing date for comments before issuing the final ACs.
Discussion
These proposed ACs provide guidance to type certificate holders and
airplane operators on how to incorporate an FAA-approved Aging Aircraft
Program into FAA-approved maintenance or inspection programs. Previous
versions of AC 91-56 (AC 91-56 and AC 91-56A) provided guidance to
operators of large transport category airplanes on how to develop a
damage-tolerance-based SSIP. In this proposed AC, the FAA expands this
guidance to small transport category airplanes. In addition, AC 91-56
and AC 91-56A considered only the effects of repair and modifications
approved by the type certificate holder and the effects of repairs and
operator-approved modifications on individual airplanes. This proposed
AC considers the effect of all major repairs, major alterations, and
modifications approved by the type certificate holder. In addition, the
AC includes an expanded discussion of repairs, alterations, and
modifications to take into consideration all major repairs and
operator-approved alterations and modifications on individual
airplanes. The proposed AC also describes the current Mandatory
Modifications Program, Corrosion Prevention and Control Program, the
Repair Assessment Program, and Evaluation for Widespread Fatigue
Damage.
