NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot stated that he was flying down a glacier for an extended period of time at a low power setting without the carburetor heat on. Near the toe of the glacier, he attempted to add power to level the airplane, but the engine did not respond. He stated that their altitude was low and he landed on the glacier moraine, and the airplane nosed over, sustaining substantial damage to the wings and fuselage. The pilot stated that there were no preaccident mechanical anomalies with the airplane that would have precluded normal operation.

Based on the temperature and dew point at the time of the accident, the conditions were favorable for serious carburetor icing at descent power.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
  • The pilot's failure to correctly use carburetor heat, resulting in a loss of engine power and collision with terrain.
