What happened
The aircraft departed Glasgow in the late afternoon for a scheduled cargo run to Campbelltown, carrying a load of movie spools. During the flight, deteriorating weather conditions prompted the crew to initiate a return to the departure airport. While attempting to navigate back through poor visibility, the airplane descended too low and struck the slope of Mt Stake near Largs, Ayrshire.
The impact resulted in the destruction of the aircraft. Both members of the flight crew sustained minor injuries but were able to walk away from the wreckage site to seek assistance. The incident involved a three-engine machine operating as a freighter.
Findings
Investigation into the accident determined that the crash was caused by a controlled flight into terrain. This outcome followed an altimeter malfunction which likely misled the crew regarding their altitude during the approach in reduced visibility conditions.
