Summary
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A300 series airplanes; Model A310 series airplanes; Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). This proposed AD was prompted by reports of cracked fuel pump canister hoods located in fuel tanks. This proposed AD would require replacing any hood halves of fuel pump canisters that are cracked. We are proposing this AD to prevent any detached canister hood fragments/debris from being ingested into the fuel feed system, and the metallic debris inside the fuel tank resulting in a potential source of ignition and consequent fire or explosion.
