Airworthiness Directives; Allison Engine Company Model AE 3007A and AE 3007A1/1 Turbofan Engines

What this AD requires

This amendment supersedes an existing airworthiness directive (AD), applicable to Allison Engine Company Model AE 3007A turbofan engines, that currently requires reprogramming the Full Authority Digital Engine Control (FADEC) to software version VI.2. This amendment requires reprogramming the FADEC to a serviceable software version and reidentifying the FADEC assembly. This amendment is prompted by reports of at least seven uncommanded engine shutdowns, four of which occurred in flight, as a result of deficiencies in software version VI.2 on the AE 3007A engines and version VI.4 on the AE 3007A1/1 engines. The actions specified by this AD are intended to prevent an unintentional or uncommanded in-flight engine shutdown.

Installed on but not limited to Embraer Model EMB-145, EMB-145ER, EMB-145MR, and EMB-145LR airplanes; applies to each identified engine regardless of modification, alteration, or repair status.

Whether AD 99-03-03 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 99-03-03 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.
