Discussion

    This proposed AC provides guidance to design approval holders on 
establishing operational limits (initial and extended) to preclude 
widespread fatigue damage for certain transport category airplanes. It 
also provides guidance for evaluating repairs and alterations to those 
airplanes for developing a means to preclude widespread fatigue damage. 
This AC also provides guidance to operators of those airplanes for use 
in incorporating Airworthiness Limitations sections with corresponding 
initial operational limits and airworthiness limitations items into 
their maintenance program. This guidance material applies to transport 
category airplanes operated under 14 CFR part 121 or part 129, that 
were certificated under the fail-safe and fatigue requirements of Civil 
Air Regulations (CAR) 4b or 14 Code of Federal Regulations (CFR) part 
25; and
    1. Have a maximum gross takeoff weight greater than 75,000 pounds, 
or
    2. Were certificated with maximum takeoff gross weight of 75,000 
pounds or less, and later increased to greater than 75,000 pounds by an 
amended type certificate or supplemental type certificate.
    It is one means, but not the only means, of complying with the part 
25 revisions proposed in Notice No. 06-04 entitled ``Widespread Fatigue 
Damage,'' which was published in the Federal Register on April 18, 2006 
(71 FR 19928). Issuance of AC 120-YY is contingent on final adoption of 
the proposed revisions to part 25.

    Issued in Washington, DC, on May 12, 2006.

Service.

Service.
