Summary
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A310-203, -204, -222, -304, -322, and -324 airplanes. This proposed AD was prompted by a design review of the fuel tank access covers and analyses comparing compliance of the access covers to different tire burst models. `Type 21' panels located within the debris zone revealed that they could not sustain the impact of the tire debris. This proposed AD would require modifying the wing manhole surrounds and replacing certain fuel access panels. We are proposing this AD to prevent a possibility of a fire due to tire debris impact on the fuel access panels.
