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
Part 91: General Aviation
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
Approach
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
Total loss of engine power (non-mechanical)
Also codedOther events the NTSB coded in the sequence, such as a wire strike after a loss of power. Flight Findings uses them for its kinds of event. Glossary
Fuel exhaustion
DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary
Substantial

Cause areas

  • Fluid, fuel › Exhaustion
  • Pilot in command › Aircraft preflight, inadequate

NTSB narrative

The aircraft lost power while on approach approximately 9 miles south of the airport. Subsequently, it nosed over during a landing in tall grass. The hobbs meter showed the duration of flight to be a total of 3.1 hours. The aircraft held 26 total gallons of fuel, with 22.5 usable. The second pilot reported to the mechanic/owner that they 'were flying at about 110 MPH, they were not at altitude, and they did little leaning.' According to the Cessna Pilot Operating Handbook (POH) for the 150L, the aircraft will burn approximately 7 gallons per hour at 2,500 feet msl with full power and using 92 percent horsepower. The POH specifies the total range to be 3.2 hours for those specific conditions. No fuel was found remaining in or around the aircraft after the accident, and the surrounding vegetation did not show signs of fuel spillage. Neither pilot reported how fuel quantity was verified or how much fuel they had on board before departure. The engine was examined by a licensed airframe and powerplant mechanic, who found no discrepancies.

Probable cause

failure of the pilot to verify the quantity of fuel before departure, and to monitor fuel consumption during the flight, which led to fuel exhaustion, loss of engine power, and a forced landing. Tall grass in the emergency landing was a related factor.

  • 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: local date, investigation status. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 1997-09-12.
