Analysis

Summary

Why the aircraft impacted the ground could not be determined.

It is possible that the air temperature and humidity affected the pilot's performance, however, the extent of any such affect could not be assessed.

The pilot's new parachute pack would have changed his position relative to the cockpit controls. A possible consequence was that, if the pilot used that relationship as a reference during manoeuvres, without adjusting for the parachute pack, the position of the flight control surfaces would also have changed when compared with previous flights performing the same manoeuvres. That could have resulted in the aircraft being operated outside the parameters previously established by the pilot for particular manoeuvres, such as by descending unintentionally.

Although the aircraft impacted the ground while tracking to the north-west, when the observer lost sight of it behind a ridge the aircraft was tracking in a south-easterly direction at a very low height. It is possible that the pilot discontinued the knife-edge manoeuvre and reversed the direction of flight while hidden from view by the ridge.
