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