- Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary

- Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary
- Initial climb
- First occurrenceThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
- Partial loss of engine power (non-mechanical)

NTSB narrative
THE PILOT AND PASSENGER WERE TAKING OFF ON THE FIRST FLIGHT OF THE DAY. THE PILOT ROTATED, RAISED THE LANDING GEAR, AND THE ENGINE BEGAN TO LOSE POWER. UNABLE TO MAINTAIN AIRSPEED, THE AIRPLANE CRASHED INTO TREES AT THE DEPARTURE END OF THE RUNWAY. WITNESSES STATED THAT THE ENGINE INITIALLY SOUNDED STRONG, THEN A GRADUAL DECREASE IN ENGINE POWER WAS HEARD. AN EXAMINATION OF THE ENGINE AFTER THE ACCIDENT REVEALED THAT THERE WAS FUEL IN THE FUEL TANKS AND CARBURETOR. AN AIRFRAME AND POWERPLANT MECHANIC WITH INSPECTION AUTHORITY REPORTED THAT CONDITIONS AT THE AIRPORT WERE CONDUCIVE TO THE FORMATION OF CARBURETOR ICE. CARBURETOR ICING CONDITIONS EXISTED, ACCORDING TO CARBURETOR ICING CHARTS.
Probable cause
THE PILOT'S IMPROPER USE OF CARBURETOR HEAT, RESULTING IN A PARTIAL LOSS OF ENGINE POWER DURING THE INITIAL CLIMB. FACTORS WERE THE CARBURETOR ICING CONDITIONS, AND THE TREES LOCATED AT THE DEPARTURE END OF THE AIRSTRIP.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
