A solo training flight from RAF Catfoss ended in a crash after an engine failure forced an emergency landing attempt, resulting in pilot injury and total loss of the aircraft.

What happened

The incident involved a twin-engine aircraft operating out of RAF Catfoss. The pilot was conducting a solo training exercise when an engine failed during flight. This mechanical issue necessitated an immediate emergency landing procedure, leading the pilot to attempt to bring the aircraft down in a nearby field.

During the final approach phase, the aircraft struck trees before impacting the ground. The collision resulted in significant structural damage, rendering the airframe damaged beyond repair. The pilot sustained injuries in the accident but survived the event.

Findings

Official investigations identified the primary factor behind the incident as an engine failure occurring while the aircraft was airborne. This mechanical malfunction directly precipitated the emergency landing attempt and subsequent collision with terrain obstacles.

Probable cause

An engine failure in flight forced an emergency landing that ended with the aircraft striking trees.
