What happened
The incident occurred while the twin-engine aircraft was on final approach to RAF Bircham Newton. During this phase of flight, the airplane descended at an altitude that was too low for the conditions. As a result, the airframe made contact with treetops before ultimately crashing into a wooded area. The impact caused significant damage, leading to the destruction of the aircraft. All four members of the crew sustained injuries in the accident.
Findings
The official investigation identified the primary contributing factor as the crew's failure to maintain adequate altitude during the approach phase. This too low approach was cited as the direct cause of the collision with terrain and vegetation.
