## Probable cause

THE PILOT'S FAILURE TO SELECT CARBURETOR HEAT IN A TIMELY MANNER, AND THE TOTAL LOSS OF ENGINE POWER DUE TO CARBURETOR ICE.  RELATED FACTORS ARE CARBURETOR ICING CONDITIONS, REDUCED VISIBILITIES IN SNOW, LOW CEILINGS, THE DARK NIGHT, AND SOFT TERRAIN CONDITIONS.

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, cruise - normal
  - weather condition - carburetor icing conditions (contributing factor)
  - carburetor heat - not selected, pilot in command (cause)
  - fuel system,carburetor - ice (cause)
- Forced landing, descent - emergency
- Nose over, landing - roll
  - weather condition - low ceiling (contributing factor)
  - weather condition - snow (contributing factor)
  - light condition - dark night (contributing factor)
  - visual lookout - restricted, pilot in command
  - terrain condition - soft (contributing factor)

## Analysis

THE AIRPLANE WAS IN CRUISE FLIGHT AT 4,000 FEET MSL IN IMC AND HEAVY SNOW WHEN THE ENGINE LOST POWER.  RESTART AND EMERGENCY PROCEDURES WERE UNSUCCESSFUL, AND A FORCED LANDING WAS MADE IN A FARM FIELD.  THE AIRPLANE NOSED OVER DURING THE LANDING ROLL.  POST-ACCIDENT EXAMINATION REVEALED NO EVIDENCE OF PRE-IMPACT MECHANICAL MALFUNCTION.  WEATHER CONDITIONS WERE CONDUCIVE TO SERIOUS INDUCTION SYSTEM ICING AT CRUISE POWER SETTINGS.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

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.
