Incident
A twin-engine aircraft was being operated on a delivery flight from Germany to Colombia, with planned stops in Iceland and Canada. Onboard were one pilot and one passenger. Approximately 20 minutes after departing Reykjavik for Goose Bay, the right engine failed. The pilot was unable to restart it and decided to divert to Nuuk for an emergency landing.
On short final approach, at a height of about 100 meters, the aircraft entered a right turn and struck the ground. The impact tore off the undercarriage, and the aircraft came to rest against an embankment. Both occupants sustained minor injuries. The aircraft was damaged beyond repair.
Investigation
Investigators examined the aircraft and found no technical malfunction except for a missing hinge pin in the injector air heating system. However, the exact cause of the engine failure could not be determined. It was reported that the pilot was not certified to perform such a flight, and the passenger was not authorized to participate according to the provisional airworthiness certificate, which was valid until the day of the occurrence.
The investigation also noted that the approach was completed at a speed approximately 10 to 15 knots below the prescribed approach speed. The possible presence of windshear on final approach was not ruled out.
Probable Cause
The official probable cause findings stated that the exact cause of the engine failure could not be determined. Except for a missing hinge pin in the injector air heating system, no technical malfunction was found. It was reported that the pilot was not certified to perform such a flight, and the passenger was not allowed to take part in such a mission according to the provisional airworthiness certificate. The possible presence of windshear on final approach was not ruled out, and the approach was completed with a speed approximately 10 to 15 knots below the prescribed approach speed.
