## Probable cause

THE IMPROPER USE OF CARBURETOR HEAT BY THE PILOT, WHICH RESULTED IN A LOSS OF ENGINE POWER AND SUBSEQUENT FORCED LANDING ON ROUGH TERRAIN.  A FACTOR RELATED TO THE ACCIDENT WAS THE LACK OF TOTAL FLIGHT EXPERIENCE OF THE STUDENT PILOT.

## Sequence of events

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

- Loss of engine power, cruise
  - weather condition - carburetor icing conditions (contributing factor)
  - carburetor heat - improper use of, pilot in command (cause)
  - lack of total experience, pilot in command (contributing factor)
- Forced landing, descent - emergency
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - soft

## Analysis

THE STUDENT PILOT WAS CRUISING AT 2500 FEET, WHEN THE ENGINE BEGAN TO RUN ROUGHLY.  CARBURETOR HEAT WAS USED AND THE ENGINE CONTINUED TO LOSE POWER. THE STUDENT MADE A FORCED LANDING IN A FIELD, AND THE AIRPLANE NOSED OVER WHEN SOFT TERRAIN WAS ENCOUNTERED.  THE SURFACE TEMPERATURE WAS REPORTED AS 83 DEGREES F, AND THE DEW POINT WAS 60 DEGREES F. THE FAA CHART, 'CONDITIONS FAVORING CARB ICE FORMATION,' SHOWS THE PROBABILITY OF 'SERIOUS ICING AT CRUISE POWER' WITH THESE TEMPERATURES.
