What this AD requires

The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to the products listed above. The reference to a "sub-section number" in paragraph (g) of the regulatory section is incorrect. This document corrects that error. In all other respects, the original document remains the same.

applicability derived from the AD summary — confirm the model/serial from the records

Whether AD 2011-12591 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 2011-12591 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.
