Loss of multiple flight deck displays, during climb 14 nm north-east of Aberdeen Airport, 27 August 2022
This statement provides the mandated update on the second anniversary of a Serious Incident which remains under investigation.聽 The Serious Incident involved an ATR 42-500, registration G-LMRC, after departure from Aberdeen Airport, on 27 August 2022.鈥�
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.鈥� The displays returned but some system faults remained.鈥� The aircraft returned to Aberdeen where it landed normally.鈥� 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.鈥� 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.鈥� In October 2023 the European Union Aviation Safety Agency published Airworthiness Directive 2023-0181 which mandated the operational test of the 1PA contactor and for it to be repeated at 1,000 flight hour intervals.聽聽
A final report will be published when the investigation has been completed.
