On 17 August 2023, a privately operated Hawker Beechcraft 390 Premier 1 on final approach to Subang suddenly departed controlled flight in benign weather conditions and crashed. The aircraft was destroyed by the impact and post crash fire and the eight occupants and two persons on the ground were killed. Control of the aircraft was lost after the aircraft lift dump spoilers were inadvertently deployed. The context for this inappropriate action was found to have been deviations from standard operating procedures, inadequate pilot training, regulatory grey areas and deficiencies in communication and decision-making between the two pilots during the flight.
