Proposed Advisory Circular 25-XX, Subpart I, Continued 
Airworthiness and Safety Improvements

AGENCY: Federal Aviation Administration, DOT.

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

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

SUMMARY: The Federal Aviation Administration invites public comment on 
proposed Advisory Circular (AC) 25-XX, ``Subpart I, Continued 
Airworthiness and Safety Improvements.'' This proposed AC provides 
generic guidance, which is applicable to the safety initiatives in the 
proposed Subpart I (i.e., Enhanced Airworthiness Program for Airplane 
Systems, Reduction of Fuel Tank Flammability in Transport Category 
Airplanes, Aging Airplane Safety, and Widespread Fatigue Damage), on 
the roles and responsibilities of type certificate and supplemental 
type certificate holders, manufacturers, owners, and operators. Like 
all ACs, it is not regulatory but provides guidance for applicants in 
demonstrating compliance with the objective safety standards set forth 
in part 25. This notice is necessary to give all interested persons an 
opportunity to present their views on the proposed AC.

DATES: Comments must be received on or before December 5, 2005.

ADDRESSES: You should send your comments to the Federal Aviation 
Administration, Attention: Mike Zielinski, Manager, AFS Liaison 
Program, ANM-105, Transport Airplane Directorate, Aircraft 
Certification Service, 1601 Lind Avenue SW., Renton, WA 98055-4056. You 
may also fax your comments to 425-227-1100, or you may send your 
comments electronically to: [email protected]. You may review all 
comments received at the above address between 7:30 a.m. and 4 p.m. 
weekdays, except Federal holidays.

FOR FURTHER INFORMATION CONTACT: Mike Zielinski at the above address, 
telephone number 425-227-2279; fax number 425-227-1100.

your comments in duplicate to the address specified above. We will

Discussion

    By separate notices published in different issues of the Federal 
Register, the FAA proposes to amend several sections of 14 CFR part 25, 
and proposes to add a new Subpart I to update the regulations. The 
proposed AC 25-XX would provide generic guidance for demonstrating 
compliance with the proposed Subpart I safety initiatives. The methods 
and procedures described in this proposed AC are similar to those used 
for certification projects. This proposed AC represents one acceptable 
means, but not the only means, of compliance with certain aspects of 
the proposed Subpart I safety initiatives.
    Issuance of the proposed AC is contingent on issuance of the 
proposed safety initiatives (i.e., Enhanced Airworthiness Program for 
Airplane Systems, Reduction of Fuel Tank Flammability in Transport 
Category Airplanes, Aging Airplane Safety, and Widespread Fatigue 
Damage).

    Issued in Washington DC, on September 22, 2005.
John J. Hickey,
Director, Aircraft Certification Service.
