What happened
During a scheduled night flight under Instrument Flight Rules (IFR) traveling from Cardiff toward Alicante, an aircraft lost control and impacted the ocean surface near Guernsey Island. The flight was carrying a total of five occupants, all of whom were lost in the accident.
Following the disappearance, search and rescue operations were launched to locate the wreckage and the crew. These efforts continued for several days; however, the mission was eventually terminated after investigators and rescuers failed to locate any debris or traces of the aircraft.
Findings
Official investigations into the incident were unable to reach a definitive conclusion regarding the precise reason for the crash due to a total lack of physical evidence from the site. Nevertheless, investigators have noted that the loss of control is suspected to have been triggered by an engine failure.
