Airworthiness Directives; Embraer S.A. Airplanes

What this AD requires

The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to certain Embraer S.A. (Embraer) Model EMB-505 airplanes. As published, two references to an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD in the preamble Background section are incorrect. This document corrects those errors. In all other respects, the original document remains the same.

As identified in ANAC AD 2023-05-03, effective June 2, 2023

Whether AD 2023-21-06 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 2023-21-06 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.
