Airworthiness Directive 2000-12-02
one-timeAirworthiness Directives; Pratt & Whitney PW4000 Series Turbofan Engines
What this AD requires
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Pratt & Whitney PW4000 Series Turbofan Engines, that currently requires revisions to the Time Limits Section of the manufacturer's Engine Manuals (EM's) to include required 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 by this 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 2000-12-02 applies to
Preamble/response-to-comments text only; states the AD applies to engines covered by three Type Certificates with an enhanced inspection program for HPT and fan life-limited rotating parts (HPC parts excluded pending further study); PW4000 cited only as an example of a full-webbed-bore HPC disk configuration. Full engine-model tables and specific part numbers referenced in the rule are not included in this excerpt.
Whether AD 2000-12-02 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.
