Action
Final rule.
Summary
The FAA is adopting 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 reports of in-flight engine shutdowns (IFESs); investigation results indicated that this could be caused by high altitude climbs at higher thrust settings on engines with certain thrust ratings. This AD requires amending the existing airplane flight manual (AFM) to incorporate a new limitation and revise certain normal procedures, as specified in a Transport Canada Civil Aviation (TCCA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
