## Probable cause

THE PILOT'S DELAY IN APPLYING CARBURETOR HEAT.

## Sequence of events

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

- Loss of engine power(partial) - nonmechanical, climb
  - weather condition - carburetor icing conditions (contributing factor)
  - carburetor heat - delayed, pilot in command (cause)

## Analysis

THE PILOT WAS PRACTICING FORCED LANDINGS WHEN THE ENGINE FAILED AFTER A GLIDING DESCENT WITH THE ENGINE AT FLIGHT IDLE. WHEN THE ENGINE FAILED TO RESPOND TO THE APPLICATION OF THROTTLE THE PILOT ATTEMPTED TO LAND ON A ROAD. THE EMPENNAGE IMPACTED A FENCE DURING THE LANDING FLARE SUBSTANTIALLY DAMAGING THE AIRCRAFT. THE TEMPERATURE/DEW POINT SPREAD WAS FAVORABLE FOR SERIOUS CARBURETOR ICING.

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.
