A twin-engine aircraft crashed into a hillside slope after encountering severe downdrafts during a night training flight from the Isle of Man, resulting in no fatalities.

What happened

The incident occurred while the crew was conducting a night training mission originating from the Isle of Man. During the en-route phase, the twin-engine aircraft entered a low-pressure weather system that generated strong downdrafts. These adverse atmospheric conditions caused the aircraft to lose altitude rapidly. The plane subsequently struck the slope of a hill and crashed. All three occupants on board were successfully rescued from the wreckage. The aircraft was declared a total loss following the impact.

Findings

The official investigation attributed the accident to the aircraft being caught by downdrafts. These sudden vertical air movements resulted in an uncontrolled loss of height, leading directly to the ground collision.

Probable cause

The crash was caused by the aircraft encountering strong downdrafts that led to a rapid loss of altitude.
