Détails:
The DC-3 lost control in icing conditions and entered a left spin. The crew managed to regain partial control before entering another left spin. The aircraft then crashed in in a diving left turn. It appeared the pilot probably lost control due to icing. Severe air loads encountered during the spin or attempted recovery caused the failure of both horizontal stabilizer and elevators.
PROBABLE CAUSE: "The Board determines that the probable cause of this accident was the loss of control of the aircraft which resulted from an icing condition, turbulence, and lack of alertness on the part of the crew. As a result, the aircraft spun, and during the spins, or attempted recovery from the spins, severe airloads were encountered which failed the left horizontal stabilizer and the elevators."
