What the agency says
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 AD was prompted by the discovery of a low clearance condition between a hydraulic motor pump harness and the airplane structure at the aft fuselage between certain frames, which was found during final airplane assembly. This proposed AD would require modification of the harness installation. The FAA is proposing this AD to address the unsafe condition on these products.
