This statement provides the mandated update on the anniversary of a ‘Serious Incident’ which remains under investigation. The serious incident involved an ATR 42-500, G-LMRC, after departure from Aberdeen Airport, on 27 August 2022. During the departure climb the aircraft suffered a loss of multiple electrical systems and the flight crew reported that all the electronic instrument display screens went blank. The displays returned but some system faults remained. The aircraft returned to Aberdeen where it landed normally. A fault with the 1PA electrical contactor was found which had probably contributed to the severity of the incident, but the underlying cause(s) are still under investigation. The aircraft manufacturer published an Airworthiness Operator Message (AOM 2022/04) in October 2022 to recommend that all operators of this aircraft type perform an operational test of the 1PA contactor. The manufacturer is currently in discussions with EASA about publishing an Airworthiness Directive to mandate this initial test and a repetitive test.
A final report will be published when the investigation has been completed.
