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

Краткое содержание

We are adopting a new airworthiness directive (AD) for all Empresa Brasileira de Aeronautica S.A. (Embraer) Model EMB-135BJ airplanes. This AD was prompted by a determination that more restrictive fuel limitations are needed. This AD requires revising the maintenance or inspection program to incorporate new compliance times and fuel limitations. We are issuing this AD to detect and correct fatigue cracking of various structural elements and prevent ignition sources in the fuel system.
