What this AD requires

The FAA is correcting a typographical error in an existing airworthiness directive (AD) that was published in the Federal Register on July 29, 2009. The error resulted in an incorrect AD number appearing in one location of the document. This AD applies to certain BAE Systems (Operations) Limited Model BAe 146-100A and 146-200A series airplanes. This AD requires inspecting for damage of the horizontal stabilizer lower skin and joint plates, and doing related investigative and corrective actions.

Whether AD E9-21039 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 E9-21039 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.
