Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD- 500-1A11 airplanes. This proposed AD was prompted by reports of wear damage found between the bonding clamps and the fuel feed tubes inside the left- and right-hand fuel tanks. This proposed AD would require repetitive inspections of the fuel feed tubes for damage, replacement if necessary, and modification of the fuel feed line installation inside the left- and right-hand fuel tanks, which would terminate the repetitive inspections, as specified in a Transport Canada Civil Aviation (TCCA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
