What happened
A flight departing from Madrid-Cuatro Vientos Airport at 16:17 local time, carrying one pilot and three passengers, encountered significant mechanical issues during its descent. After cruising at FL230, the aircraft received clearance from Palma ARTCC to descend to FL130. During this phase of flight, the crew observed a drop in engine torque accompanied by rising turbine temperatures.
The pilot performed multiple attempts to address potential issues within the fuel supply system and inspected the fuel selector, but these troubleshooting efforts failed to restore engine performance. As the aircraft descended toward 9,000 feet, the indicated airspeed dropped to 80 knots. At 17:22 local time, an emergency was declared to air traffic control.
Realizing that the destination of Palma Airport was no longer reachable, the pilot executed a ditching maneuver in the Mediterranean Sea. The aircraft came to rest approximately 27.7 km north of Ibiza Island. While all four occupants were successfully rescued without injury, the aircraft subsequently sank and was lost.
Findings
Because the wreckage could not be recovered, investigators were unable to confirm a definitive reason for the accident. However, investigators did not rule out a technical failure of the fuel supply system as the primary cause of the engine power loss.
