## Probable cause

IMPROPER USE OF THE CARBURETOR HEAT CONTROL WHICH RESULTED IN CARBURETOR ICE AND SUBSEQUENT LOSS OF POWER. A FACTOR RELATED TO THE ACCIDENT WAS THE CARBURETOR ICING CONDITIONS WHICH EXISTED AT THE TIME OF THE ACCIDENT.

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, takeoff - initial climb
  - weather condition - carburetor icing conditions (contributing factor)
  - carburetor heat - improper use of, pilot in command (cause)
- Forced landing, descent - emergency
- In flight collision with terrain/water, landing - flare/touchdown
  - terrain condition - none suitable

## Analysis

SHORTLY AFTER TAKEOFF AT AN ALTITUDE OF APPROXIMATELY 50 FT AGL, A LOSS OF ENGINE POWER WAS EXPERIENCE. A FORCED LANDING WAS MADE IN A FIELD DURING WHICH THE LANDING GEAR COLLAPSED. POST ACCIDENT INSPECTION FAILED TO REVEAL ANY MECHANICAL FAILURE. IT WAS NOTED THAT THE SPARK PLUGS WERE HEAVILY SOOTED. METEOROLOGICAL CONDITIONS WERE CONDUCIVE TO CARBURETOR ICING. AUTOMOTIVE GAS WAS BEING USED IN THE AIRPLANE AT THE TIME OF THE ACCIDENT.
