Airworthiness Directives; Pratt & Whitney JT9D Series Turbofan Engines; Correction

What this AD requires

This document makes a correction to Airworthiness Directive (AD) 99-15-02 applicable to certain Pratt &Whitney (PW) JT9D series turbofan engines that was published in the Federal Register on July 16, 1999 (64 FR 38299). Part number (P/N) and service bulletin (SB) references in the compliance section are incorrect. This document corrects those references. In all other respects, the original document remains the same.

certain

Whether AD 99-26710 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 99-26710 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.
