Summary
This document proposes the supersedure of an existing airworthiness directive (AD), applicable to certain Airbus Model A310 and A300-600 series airplanes. The existing AD requires a detailed visual inspection to detect damage to the terminal lugs on the 12XC and 15XE connectors and the mounting lugs on the 15XE connector; corrective actions, if necessary; and certain conditional repetitive inspections. This action would add requirements for installation of a new mounting bracket for the 15XE connector, modification of the cable attachment adjacent to the connector, and replacement of certain terminal lugs on the 15XE connector by terminal lugs with a thicker contact area. This proposal is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by the proposed AD are intended to prevent excessive vibrations generated by the mounting configuration of the 15XE connector, which could cause breakage of the terminal and mounting lugs on the 15XE connectors in the 101VU panel in the avionics compartment, resulting in loss of electrical power from the standby generator.
