Airworthiness Directives; Airbus Industrie Model A300, A310, and A300-600 Series Airplanes

概要

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A300, A310, and A300-600 series airplanes, that requires inspections to detect missing fasteners, cracked fitting angles, and elongated fastener holes in certain frames, and correction of discrepancies. It also provides an optional terminating action. This amendment is prompted by discrepancies found at the fitting angles on the frame at which a certain electronic rack is attached. The actions specified by this AD are intended to prevent damage propagation that could lead to failure of the rack-to-structure attachment points, and subsequently could result in loss of airplane systems, structural damage, and possible electrical arcing.
