## Probable cause

IMPROPER USE OF THE CARBURETOR HEAT BY THE PILOT RESULTING IN THE FORMATION OF CARBURETOR ICE AND SUBSEQUENT LOSS OF POWER.

## Sequence of events

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

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

## Analysis

THE PILOT STATED THAT DURING A NORMAL DESCENT TO THE DESTINATION AIRPORT, THE ENGINE LOST POWER. AN EMERG LANDING WAS MADE RESULTING IN SUBSTANTIAL DAMAGE TO THE ACFT. POST ACCIDENT INVESTIGATION REVEALED NO MECHANICAL MALFUNCTIONS, OR EVIDENCE OF FUEL EXHAUSTION. METEOROLOGICAL CONDITIONS AT THE TIME WERE CONDUCIVE FOR THE PROBABILITY OF CARBURETOR ICING ACCORDING TO THE 'ICING PROBABILITY CHARTS'.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
