Airworthiness Directives; Boeing Model 747 Series Airplanes Powered by Pratt & Whitney JT9D-3 and -7 Series Engines

What this AD requires

This document corrects a minor error that appeared in airworthiness directive (AD) 2000-23-16, that was published in the Federal Register on November 21, 2000 (65 FR 69862). The error resulted in a reference to a part number that does not exist. That AD is applicable to certain Boeing Model 747 series airplanes, and requires repetitive inspections and torque checks of the hanger fittings and strut forward bulkhead of the forward engine mount and adjacent support structure, and corrective actions, if necessary. That AD also provides for optional terminating action for the repetitive inspections and checks.

Repetitive inspection. Re-inspect. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

certain

Whether AD 2000-23-16 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 2000-23-16 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.
