What this AD requires

The FAA is correcting airworthiness directive (AD) 2009-10-01, which was previously published in the Federal Register. That AD applies to PW JT9D-7R4 series turbofan engines. In the Federal Register, the AD number in the CFR citation of the headings section is incorrect. This document corrects that AD number. In all other respects, the original document remains the same.

Whether AD E9-11477 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 E9-11477 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.
