The DC-3 crashed into a hillside after the in-flight separation of the right wing.

ASSIGNED CAUSE: "The accident was caused by in-flight separation of the starboard wing due to a loss of structural strength brought about by extensive fatigue cracks in the lower centre wing wraparound and internal doublers inboard of Sta. 142, initiation and propagation to failure of the RH wing cracks being due to consistent overstress."
