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 a report that threaded fuel couplings were incorrectly installed at final assembly and in service. This proposed AD would require repetitive functional tests of the auxiliary power unit (APU) fuel feed line shroud, a general visual inspection of the APU feed line shroud for any loose couplings; and tightening any loose couplings, which would terminate the repetitive functional tests. The FAA is proposing this AD to address the unsafe condition on these products.
