## Sequence of events

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

- Loss of engine power(total) - nonmechanical, cruise - normal
  - weather condition - carburetor icing conditions (contributing factor)
  - carburetor heat - improper use of, pilot in command (cause)
  - fuel system,carburetor - ice (cause)
- Forced landing, landing - flare/touchdown
- Nose over, landing - roll
  - terrain condition - soft (contributing factor)

## Analysis

THE PILOT REPORTED THAT THE ENGINE RPM BEGAN DROPPING WHILE HE WAS CRUSING AT 2500 FT. WHEN CARBURETOR HEAT WAS APPLIED, THE ENGINE STOPPED RUNNING. THE PILOT WAS ABLE TO RESTART THE ENGINE AND GET IT TO 1200 PRM, BUT IT STOPPED AGAIN. A FORCED LANDING WAS MADE IN A SOFT FIELD WHERE THE PLANE NOSED OVER. AN INSPECTION AND OPERATIONAL CHECK OF THE ENGINE REVEALED NO PRECRASH, MECHANICAL MALFUNCTION OR FAILURE. THE TEMPERATURE AND DEW POINT WERE 34 AND 24 DEGREES, RESPECTIVELY. ACCORDING TO ICING PROBABILITY CHARTS, ICING COULD OCCUR IN IN FLOAT TYPE CARBURETORS IN CRUISE FLIGHT AT THOSE TEMPERATURES.
