## Summary

This document revises an earlier proposed airworthiness directive (AD), applicable to certain Airbus Model A300, A310, and A300-600 series airplanes, that would have required inspections to detect missing fasteners, cracked fitting angles, and elongated fastener holes in certain frames, and correction of discrepancies. That proposal was prompted by discrepancies found at the fitting angles on the frame at which a certain electronic rack is attached. This action revises the proposed rule by revising the inspection thresholds and repetitive intervals; providing an optional terminating action; and deleting certain airplanes from the applicability. The actions specified by this proposed 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.
