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

This amendment adopts a new airworthiness directive (AD), applicable to all Airbus Model A300, A310, and A300-600 series airplanes, that requires repetitive mechanical and electrical inspections to detect chafing of electrical wiring; and repair or replacement of discrepant parts, and repositioning the looms. This amendment is prompted by reports of wire chafing in the forward avionic compartment. The actions specified by this AD are intended to prevent such chafing, which may lead to a short in the electrical circuits at the 104VU panel; this condition could result in unwanted depressurization, loss of wing de-icing, and loss of in-flight engine restart capability.
