Summary
The FAA is superseding Airworthiness Directive (AD) 2025-06- 01, which applied to all Airbus Canada Limited Partnership Model BD- 500-1A10 and BD-500-1A11 airplanes. AD 2025-06-01 required revising the existing airplane flight manual (AFM) to incorporate the procedures for the flightcrew to manually isolate the opposite functional engine in the event of an engine bleed duct large leak condition. Since the FAA issued AD 2025-06-01, an electronic engine control (EEC) software update has been developed to address the unsafe condition. This AD continues to require the actions in AD 2025-06-01 and requires installing a certain EEC software update on both engines. This AD also removes airplanes from the applicability. The FAA is issuing this AD to address the unsafe condition on these products.
