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

We are adopting a new airworthiness directive (AD) for certain Empresa Brasileira de Aeronautica S.A. (Embraer) Model EMB-135BJ airplanes. This AD was prompted by reports of failure of the bolts that connect the cockpit windshield center-post to the forward fuselage. This AD requires repetitive detailed inspections to detect discrepancies on the attaching parts of the cockpit windshield center- post; checking whether the bolts are tightened, if applicable; and modifying parts, including inspecting for and repairing damage. We are issuing this AD to prevent failed bolts and failed attaching parts of the cockpit windshield center-post, which could lead to loss of structural integrity of the airplane.
