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

概要

We propose to adopt a new airworthiness directive (AD) for all Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB -135ER, - 135KE, -135KL, -135LR, -145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. This proposed AD was prompted by our determination of the need to revise the airplane airworthiness limitations to the pylon and fuselage. This proposed AD would require revising the maintenance or inspection program. We are proposing this AD to prevent fatigue cracking of various structural elements, which could affect the structural integrity of the airplane.
