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 proposed AD was prompted by reports that the interface pin of the secondary load path in the upper gimbal of the horizontal stabilizer trim actuator (HSTA) was incorrectly installed. This proposed AD would require a detailed visual inspection of the interface pin of the HSTA to determine if the interface pin is incorrectly installed, and applicable on-condition actions as specified in a Transport Canada AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
