Airworthiness Directive · Amendment 39-12302 · Airbus Model A310, and Model A300 B4-600, A300 B4-600R, and A300 F4-600R (Collectively Called A300-600) Series Airplanes
Airbus Model A310, and Model A300 B4-600, A300 B4-600R, and A300 F4-600R (Collectively Called A300-600) Series Airplanes
The following airplanes, certificated in any category, and equipped with a standby generator (FIN 25XE); excluding airplanes on which Airbus Modification 12135 has been accomplished: Model A300 B4-600, A300 B4-600R and Model A300 F4-600R (collectively called A300-600) series airplanes on which Airbus Modification 06213 has been installed; and Model A310 series airplanes on which Airbus Modification 05910 has been installed.
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A310 and A300-600 series airplanes, that currently requires a detailed visual inspection to detect damage to the terminal lugs on the 12XC and 15XE contactors and the mounting lugs on the 15XE contactor; corrective actions, if necessary; and certain conditional repetitive inspections. This action adds requirements for installation of a new mounting bracket for the 15XE contactor, modification of the cable attachment adjacent to the contactor, and replacement of certain terminal lugs on the 15XE contactor by terminal lugs with a thicker contact area. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent excessive vibrations generated by the mounting configuration of the 15XE contactor, which could cause breakage of the terminal and mounting lugs on the 15XE contactors in the 101VU panel in the avionics compartment, resulting in loss of electrical power from the standby generator.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
