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.

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.

Director, Aircraft Certification Service.
