## Probable cause

IMPROPER USE OF CARBURETOR HEAT BY THE PILOT, WHICH RESULTED IN CARBURETOR ICE.  A FACTOR RELATED TO THE ACCIDENT WAS:  CARBURETOR ICING 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
  - weather condition - carburetor icing conditions (contributing factor)
  - carburetor heat - improper use of, pilot in command (cause)
  - fuel system,carburetor - ice (cause)
- Forced landing, descent - emergency
- In flight collision with terrain/water, landing

## Analysis

THE PILOT SAID THAT DURING A CROSS COUNTRY PERSONAL FLIGHT, THE ENGINE LOST POWER. SUBSEQUENTLY, THE ACFT WAS DAMAGED DURING A FORCED LANDING. A POST ACCIDENT INVESTIGATION FAILED TO REVEAL ANY ENGINE ABNORMALITIES OR MALFUNCTIONS. ACCORDING TO ICING PROBABILITY CHARTS, METEOROLOGICAL CONDITIONS WERE CONDUCIVE FOR CARBURETOR ICING AT THE TIME OF THE ACCIDENT.
