## Probable cause

THE FORMATION OF CARBURETOR ICE WHEN THE PILOT DELAYED THE USE OF CARBURETOR HEAT.

## 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
  - carburetor heat - delayed, pilot in command (cause)
- Forced landing, descent - emergency
- Gear collapsed, landing - roll
  - terrain condition - rough/uneven (contributing factor)

## Analysis

WHILE CRUISING BETWEEN CLOUD LAYERS THE PILOT NOTICED THE AIRSPEED WAS LOW AND APPLIED THE CARBURETOR HEAT. THE ENGINE DID NOT CHANGE FOR A FEW MINUTES AND THEN QUIT. THE PILOT WAS UNABLE TO GET THE ENGINE TO CONTINUE TO RUN AND MADE A FORCED LANDING WHICH DAMAGED THE AIRCRAFT. SURFACE TEMPERATURE AT THE TIME WAS REPORTED TO BE 30 DEGREES WITH A DEW POINT OF 21 DEGREES.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

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.
