Airworthiness Directives; Airbus Model A300 B4-600, B4-600R, and F4-600R Series Airplanes and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes)

摘要

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Model A300-600 series airplanes. This proposed AD would require revising the Airworthiness Limitations Section of the Instructions for Continued Airworthiness to incorporate new limitations for fuel tank systems. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors caused by latent failures, alterations, repairs, or maintenance actions, could result in fuel tank explosions and consequent loss of the airplane.
