Airworthiness Directives; Embraer S.A. (Type Certificate Previously Held by Yaborã Indústria Aeronáutica S.A.; Embraer S.A.) Airplanes

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 170 airplanes. This AD was prompted by a report of a landing gear not locked indication during the final approach, which led the flight crew to declare an emergency. This AD requires reviewing maintenance records of the main landing gear (MLG) assemblies to determine whether the MLG was modified according to a certain service bulletin or restored during overhaul maintenance; inspecting the left and right MLG locking-stay bracket assemblies to verify that the correct attaching hardware is correctly installed on the brackets; replacing nuts having certain part numbers (P/Ns); replacing the locking-stay bracket assembly, if necessary; and prohibits the installation of affected parts on the MLG locking-stay bracket assembly; as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

Whether AD 2024-13938 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.

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.
