On 23 January 2020, a Cessna S550 departed George to conduct a calibration flight under VFR with three persons on board and was about to begin a DME arc at 4,000 feet QNH when control was lost after entering IMC. Recovery from a significant descent which followed was not achieved before the aircraft hit mountainous terrain 1,800 feet below and was destroyed killing all occupants. The Investigation considered that the transition into IMC had probably occurred without preparation and that the inability of the crew to perform a prompt recovery reflected unfavourably on the conduct of the aircraft operator.
