## Abstract

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.
