Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (Embraer) Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) for certain Empresa Brasileira de Aeronautica S.A. (Embraer) Model EMB-135ER, - 135KE, -135KL, and -135LR airplanes and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. This AD was prompted by reports of internal corrosion of the stow/transit switches installed in the engine thrust reversers. This AD requires installation of new stow/ transit switches. We are issuing this AD to address the unsafe condition on these products.

Applies to airplanes identified in Embraer Service Bulletin 145-78-0035, Revision 03, dated November 26, 2004; excludes airplanes identified in Revision 02, dated January 31, 2003.

Whether AD 2019-03-30 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 2019-03-30 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.
