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 discovery that the outflow valve (OFV) direct current (DC) motor could potentially be inoperative when used in high differential pressure conditions. This AD prohibits dispatching an airplane under certain master minimum equipment list (MMEL) items and prohibits dispatching if a certain crew alerting system (CAS) message is displayed. The FAA is issuing this AD to address the unsafe condition on these products.
