What happened
The incident occurred immediately following departure from RAF Finningley (Doncaster Airport). While executing the initial climb segment of the flight, the twin-engine aircraft experienced an aerodynamic stall. The loss of lift caused the plane to descend rapidly into a nearby wooded area, where it impacted the ground and subsequently caught fire. The post-crash blaze completely destroyed the airframe.
The accident resulted in significant casualties among the occupants. Three passengers lost their lives in the event. Two other individuals on board sustained serious injuries. The source material identifies the crew as belonging to the 4th Squadron, consisting of two pilots and an Air Chief Marshal Second Class (AC2), though specific names are omitted in accordance with privacy guidelines for private individuals.
Findings
The primary mechanical or operational failure identified was a stall occurring during the initial climb phase. This event directly led to the loss of control and the subsequent impact with terrain. The destruction of the aircraft by fire prevented further structural analysis, but the sequence of events confirms that the crash was precipitated by the stall shortly after takeoff.
