## Probable cause

IMPROPER USE OF CARBURETOR HEAT BY THE PILOT, WHICH RESULTED IN CARBURETOR ICE.   FACTORS RELATED TO THE ACCIDENT WERE:  CARBURETOR ICING CONDITIONS, AND SOFT TERRAIN.

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, descent
  - weather condition - carburetor icing conditions (contributing factor)
  - fuel system,carburetor - ice (cause)
  - carburetor heat - improper use of, pilot in command (cause)
- Forced landing, descent - emergency
- In flight collision with terrain/water, landing - flare/touchdown
  - terrain condition - soft (contributing factor)

## Analysis

AFTER DESCENDING FM 2500 TO 2000 FT, THE PLT REALIZED THE ENG HAD LOST PWR, WHEN IT DID NOT RESPOND TO THROTTLE MOVEMENTFOR LEVEL OFF. HE MOVED THE CARBURETOR HEAT TO THE 'ON' POSITION, BUT WAS UNABLE TO RESTART THE ENG. SUBSEQUENTLY, HE MADE AN EMERGENCY LANDING IN A PLOWED FIELD & THE LANDING GEAR COLLAPSED ON SOFT TERRAIN. THE CARBURETOR WAS DAMAGED DURING THE OCCURRENCE. AFTER IT WAS REPLACED, THE ENG WOULD OPERATE. AN EXAM OF THE DAMAGED CARBURETOR REVEALED ONLY NORMAL WEAR. THE TEMP & DEW POINT WERE 64 & 44 DEG, RESPECTIVELY. ACCORDING TO CARBURETOR ICING CHARTS, CONDITIONS WERE CONDUCIVE TO CARBURETOR ICE.
