Synopsis

After a series of aerobatic manoeuvres the aircraft completed a stall turn and entered a vertical dive from which it did not recover. Examination of the wreckage revealed the presence of a short-handled flat bladed screwdriver that had jammed the elevator control such that the elevator control surface could not be moved beyond neutral in the nose-up direction.
