## Probable cause

THE PILOT ELECTED TO FLY INTO KNOWN ADVERSE WEATHER AND ENCOUNTERED ICING CONDITIONS. CONTRIBUTING TO THE ACCIDENT WAS THE PILOT'S INADEQUATE EVALUATION OF THE WEATHER AND A LOSS OF ENGINE POWER FOR UNDETERMINED REASONS.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- In flight encounter with weather, climb - to cruise
  - weather condition - icing conditions (cause)
  - flight into known adverse weather - continued, pilot in command (cause)
  - weather evaluation - inadequate, pilot in command (contributing factor)
- Loss of engine power, climb - to cruise
  - reason for occurrence undetermined (contributing factor)
- Forced landing, descent - emergency
- Ditching, descent - emergency

## Analysis

DURING THE CLIMB TO CRUISE PHASE, SHORTLY AFTER TAKEOFF, THE PILOT REPORTED THAT THE AIRPLANE WAS PICKING UP RIME ICE AND THE ENGINE WAS RUNNING ROUGH.  THE FLIGHT WAS CLEARED TO RETURN TO THE AIRPORT, HOWEVER, THE FLIGHT WAS UNABLE TO RETURN AND WAS DITCHED IN THE GREAT SALT LAKE. THE AIRPLANE WAS NOT RECOVERED.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
