Plain English Summary

3/10 complexity

The Civil Aviation Safety Authority issued a mandatory Airworthiness Directive forcing operators of Airbus A320-111 and A320-211 aircraft to replace specific transformer rectifier units with updated models. The change addresses a failure mode that could lead to loss of multiple flight control computers, so operators had to comply under strict 1989 deadlines to restore and maintain airworthiness.
