Airworthiness Directive · Amendment 39-14308 · Airbus Model A300 B4-620, A310-304, A310-324, and A310-325 Airplanes
Airbus Model A300 B4-620, A310-304, A310-324, and A310-325 Airplanes
This AD applies to Airbus Model A300 B4-620, A310-304, A310-324, and A310-325 airplanes, certificated in any category; equipped with one or more auxiliary center tank (ACT), except those on which Airbus Modification 12471 has been accomplished in production.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A300 B4-620, A310-304, A310-324, and A310-325 airplanes. This AD requires installing fused adaptors between the external wiring harness and the in-tank wiring at the connectors on the fuel tank wall of the auxiliary center tank (ACT). This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent an ignition source in the ACT, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 24 months after the effective date of this AD: Install fused adaptors between the external wiring harness and the in-tank wiring at the connectors on the fuel tank wall of the ACT by doing all the actions specified in the Accomplishment Instructions of the applicable service bulletin in Table 1 of this AD.
