## Probable cause

THE PILOT'S FAILURE TO USE CARBURETOR HEAT WHILE FLYING IN 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 (cause)
  - carburetor heat - not used, pilot in command (cause)
- In flight collision with terrain/water, descent - emergency

## Analysis

THE PILOT SUSTAINED SERIOUS HEAD INJURIES IN THE ACCIDENT AND HAS NO RECOLLECTION OF THE EVENTS SURROUNDING THE ACCIDENT.  AN INSPECTION OF THE AIRPLANE DISCLOSED NO MECHANICAL PREIMPACT ANOMALIES.  FUEL WAS PRESENT IN THE FUEL TANKS, LINES AND CARBURETOR.  TEMPERATURE AND DEW POINT RECORDED AT A NEARBY AIRPORT WERE 54 AND 46 DEGREES, WHICH EQUATES TO A 'SERIOUS' ICING PROBABILITY ON A CARBURETOR ICING PROBABILITY CHART. THE CARBURETOR HEAT SELECTOR IN THE COCKPIT WAS FOUND POSITIONED 'OFF'.

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.
