Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A320-111, -211, -212, and -231 airplanes. This proposed AD would require, for certain airplanes, modifying the cables and access holes to the inner tank fuel pumps; and, for certain other airplanes, inspecting the fuel pump access holes and modifying the access holes, if necessary. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent chafing of the fuel pump cables, which could result in electrical arcing and possible ignition of fuel vapors and consequent explosion of the fuel tank.
