Airworthiness Directive 00-27166
one-timeAirworthiness Directives; Pratt & Whitney PW2000 Series Turbofan Engines
What this AD requires
This amendment adopts a new airworthiness directive (AD), applicable to Pratt & Whitney (PW) PW2000 series turbofan engines, that requires revisions to the time limit sections (TLS) of the manufacturer's Engine Manuals to include enhanced inspection of selected critical life-limited parts at each piece-part exposure. This action adds additional critical life-limited parts for enhanced inspection. This amendment is prompted by additional focused inspection procedures for other critical life-limited rotating engine parts that have been developed by the manufacturer. The actions specified in the AD are intended to prevent critical life-limited rotating engine part failure, which could result in an uncontained engine failure and damage to the airplane.
Which aircraft AD 00-27166 applies to
Installed on but not limited to Boeing 757 series and Ilyushin IL-96T series airplanes.
Whether AD 00-27166 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
