The crew was completing a local training mission at RAF Ballykelly. The approach was performed with one engine voluntarily inoperative. After touchdown, the airplane rolled over a long distance then veered off runway and came to rest in flames. All four crew members escaped uninjured while the aircraft was destroyed.

The crew was performing a flight from RAF Bovingdon to RAF Ballykelly on behalf of the coastal communications commando. While in cruising altitude, the crew was informed about the deterioration of the weather conditions at destination and was instructed to divert to RAF Valley. Shortly later, while flying in clouds, the airplane struck the slope of Mt Tal y Fan. The aircraft was demolished and all three crew members were killed.

Belly landed for unknown reason and came to rest. There were no injuries but the aircraft was damaged beyond repair.

The crew was taking part to an antisubmarine exercice from RAF Ballykelly.

The crew (269th Squadron) was engaged in a training sortie. During the takeoff run, the pilot-in-command started the rotation but the aircraft did not respond. The captain decided to abandon the takeoff procedure and started an emergency braking maneuver. Unable to stop within the remaining distance, the aircraft overran and came to rest dozen yards farther. While all seven crew members were unhurt, the aircraft was damaged beyond repair.

The aircraft departed RAF Ballykelly to conduct radar homings on a submarine in the Lough Foyle - Rathlin Island area; this exercise was to be followed by a navigation exercise. The crew completed the anti-submarine procedures and made its last radio call at 1715LT. At 1730LT several civilians on the Isle of Mull heard a low-flying aircraft and an explosion. Wreckage was found on the Isle of Mull and the nearby mainland, although it is not clear whether this wreckage was found on the coastline or further inland. All 10 crew died in the accident. The condition of some of the wreckage indicated an extremely violent impact, but the cause of the accident was never established. In March 1954, further wreckage was found in the Sound of Mull which led experts to conclude that the aircraft appeared to have struck the water whilst turning to starboard in a nose down attitude. A search of the high ground on the Isle of Mull did not reveal any evidence of a glancing impact. Contemporary press cuttings indicate that it crashed in the Sound of Mull with the wreckage being found by the frigate HMS Volage on 13th December 1953. A month later a further cutting reports two bodies being found.
