Summary
We propose to adopt a new airworthiness directive (AD) for certain Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB- 135BJ airplanes. This proposed AD was prompted by reports of failure of the bolts that connect the cockpit windshield center-post to the forward fuselage. This proposed AD would require 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. The modification would terminate the repetitive inspections. We are proposing 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.
