The aircraft was on a private flight from Dundee Airport to Tiree Airport. While established in the cruise at an altitude of 6,500 ft it entered a gentle right turn, the rate of which gradually increased with an associated high rate of descent and increase in airspeed. The aircraft struck the western slope of a mountain, Beinn nan Lus, in a steep nose-down attitude. Both persons on board were fatally injured.
No specific cause for the accident could be identified but having at some point entered IMC, the extreme aircraft attitudes suggest that the pilot was experiencing some form of spatial disorientation and the recorded data and impact parameters suggest that the accident followed a loss of control, possibly in cloud.
