Airworthiness Directives; Airbus Model A300 B4-2C, B4-103, and B4-203 Series Airplanes; and Model A300-600 B4-620, B4-622, B4-603, and B4-601 Series Airplanes

Resumen

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A300 and A300-600 series airplanes. This proposal would require modification of the fuel tank jettison system. This proposal is prompted by a quality survey which revealed that the electrical bonding of the fuel jettison system has insufficient protection from a lightning strike. The actions specified by the proposed AD are intended to prevent electrical arcing and resultant fire in the event of a lightning strike.
