What this AD requires

This document makes a correction to Airworthiness Directive (AD) 99-03-09 applicable to Allison Engine Company Model AE 3007A turboprop engines that was published in the Federal Register on February 4, 1999 (64 FR 5592). The contact office address was omitted. This document corrects that omission. In all other respects, the original document remains the same.

Whether AD 99-4016 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 99-4016 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.
