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

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for all Yabor[atilde] Ind[uacute]stria Aeron[aacute]utica S.A. Model EMB-135 and EMB-145 airplanes. This AD was prompted by a report involving disconnection of a side arm strut from the right main landing gear (MLG); a subsequent investigation found that the side arm strut lower bearing was installed inverted on the airplane. This AD requires doing a general visual inspection of the right and left MLG to verify certain conditions and doing all applicable on-condition actions, 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 2021-07010 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 2021-07010 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.
