The rudder and ailerons could be seen to move during the final manoeuvre but the elevator
remained fully up. This would have required positive back pressure on the control stick to be
maintained, or a jam in the control system. There was no evidence of the pilot having a problem
with the flight controls earlier in the flight so it is more likely that the stick was held in this
position. The flight control inputs at the top of the final manoeuvre, in particular the rudder, were
not consistent with a display manoeuvre or a recovery action. In fact, they were similar to the
control positions used to effect deliberate entry into a spin and the aircraft entered an incipient spin.
From consideration of the evidence and the experience of the pilot, it seems likely that an unknown
factor affected the pilot's physical and/or mental performance during the display.
