What happened
The crew departed RAF Worthy Down to conduct a local training mission. During the approach phase, while flying at an altitude of approximately 700 feet, the pilot-in-command reduced engine power by throttling back. This action caused the aircraft to lose height unexpectedly. As the airplane descended, the left wing struck the station headquarter building before the aircraft crashed. The impact resulted in three fatalities among the occupants and injured a fourth person on board. Additionally, nine individuals inside the building sustained injuries in the incident.
Findings
The accident occurred during a routine local training flight. The critical sequence involved the reduction of engine power during the approach, which led to an uncontrolled loss of altitude. This loss of height directly caused the left wing to collide with the adjacent infrastructure, leading to the crash and subsequent casualties.
