What happened
During a flight along the coastline, the aircraft's left engine experienced a failure while in the cruise phase. Following this initial malfunction, the right engine also lost power and ceased operating. Faced with a total loss of propulsion, the pilot descended to a lower altitude and performed a ditching maneuver in the sea, roughly 10 miles south of Swansea.
All eleven people on board survived the impact. The occupants managed to remain on the aircraft's wings until they were reached by the crew of a nearby fishing vessel. While the passengers and crew were successfully rescued, the aircraft subsequently sank and remains lost at the site of the accident.
Findings
Investigations into the incident determined that the primary factor was a double engine failure occurring in rapid succession.
