Narrative:Viscount G-AOHI departed Glasgow at 14:22 GMT on a test flight which was to last about 15 minutes. The crew intended to carry out the flight in visual conditions. Weather conditions however, were marginal: rain and snow with 6 km visibility, 8/8 clouds at 4000 feet and strong winds (50-60 knots) at 2000 feet.
The plane had climbed to an altitude of 4000 feet when it crashed near the peak of Ben More mountain, 35 miles north of Glasgow.
Probable Cause:CAUSE: "The aircraft struck a mountain peak whilst flying over snow covered high terrain in marginal visual meteorological conditions. Failure to maintain a safe altitude and insufficient attention to navigational procedures were contributory factors."
