## Sequence of events

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

- Loss of engine power(partial) - mech failure/malf, cruise - normal
  - aircraft preflight - inadequate, pilot in command (cause)
  - carburetor heat - not selected, pilot in command (cause)
  - weather condition - carburetor icing conditions (contributing factor)
  - ignition system,magneto - failure,partial (contributing factor)
  - fuel system,carburetor - ice (contributing factor)
- Forced landing, landing - flare/touchdown
  - terrain condition - crop (contributing factor)

## Analysis

THE ACFT WAS FORCED TO LAND IN A FARM PASTURE AFTER THE ENGINE LOST POWER. POST ACCIDENT EXAMINATION OF THE ACFT REVEALED THAT THE CARBURETOR HEAT CONTROL WAS OFF. THE RIGHT MAGNETO WAS FOUND TO BE VERY WEAK. A SPARK COULD ONLY BE PRODUCED AT HIGH RPM. THE SPARK PLUGS SHOWED EVIDENCE OF OPERATING FOR A TIME WITH AN OVERLY RICH MIXTURE.

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.
