## Probable cause

IMPROPER USE OF THE CARBURETOR HEAT BY THE PILOT WHICH RESULTED IN A POWER LOSS DUE TO CARBURETOR ICE OVER UNSUITABLE TERRAIN.

## Sequence of events

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

- Loss of engine power, climb
  - weather condition - carburetor icing conditions (contributing factor)
  - in-flight planning/decision - improper, pilot in command
  - carburetor heat - improper use of, pilot in command (cause)
- Forced landing, descent - emergency
- In flight collision with object, landing - flare/touchdown
  - object - tree(s) (contributing factor)

## Analysis

THE PILOT TOOK OFF, AND AS HE LEVELED OFF AT 3000 FEET, HE EXPERIENCED A PARTIAL POWER LOSS.  USE OF CARBURETOR HEAT CAUSED MORE OF A POWER LOSS. THE PILOT SAID THERE WAS INSUFFICIENT ALTITUDE TO MELT THE ICE. AN OFF AIRPORT LANDING WAS MADE IN A WOODED AREA.  AFTER THE ACCIDENT, THE AIRPLANE ENGINE WAS TEST RUN WITH 'NO APPARENT DEFECTS.'
