What this AD requires

This document makes a correction to Airworthiness Directive (AD) 2003-19-15, applicable to Pratt & Whitney PW4000 series turbofan engines. AD 2003-19-15 was published in the Federal Register on September 30, 2003 (68 FR 56143). In the amendatory language, under Sec. 39.13 [Amended], the amendment number of the new action was inadvertently omitted. This document corrects that omission. In all other respects, the original document remains the same.

Whether AD 03-25577 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:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

Is AD 03-25577 complied with on your aircraft?

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.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
