## Probable cause

THE PILOTS FAILURE TO USE CARBURETOR HEAT PROPERLY. CONTRIBUTING TO THE ACCIDENT WERE THE 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)
  - fuel system,carburetor - ice
  - carburetor heat - improper use of, pilot in command (cause)
- Forced landing, descent - emergency
- In flight collision with object, landing
  - object - tree(s)

## Analysis

DURING AN SOLO INSTRUCTIONAL CROSS COUNTRY FLIGHT, THE PLT SAID THAT THE ENGINE BEGAN TO LOSE POWER, THEN QUIT. AN EMERGENCY LANDING WAS ATTEMPTED WHICH RESULTED IN A COLLISION WITH SOME TREES. POST ACCIDENT INVESTIGATION AND ENGINE RUN-UP REVEALED NO MECHANICAL MALFUNCTION OR FUEL SHORTAGE. METEOROLOGICAL CONDITIONS AT THE TIME WERE CONDUCIVE FOR CARBURETOR ICING, ACCORDING TO THE 'ICING PROBABLILITY CHARTS'.
