ACTION: Final rule. SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. This AD was prompted by the determination that reliance on design assurance level (DAL) D software for flight-critical fly-by-wire (FBW) rigging functions may result in undetected inaccurate positioning of the primary flight control surfaces. This AD requires the use of specific issues of the aircraft maintenance publication (AMP) for electrical rigging procedures, and an electrical rigging confirmation check of primary flight control surfaces for certain airplanes, as specified in a Transport Canada AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective June 28, 2024. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of June 28, 2024.
