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
Initial climb
Defining eventThe 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
Fuel exhaustion
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

NTSB narrative

The non-certificated pilot was observed by airport personnel as he assembled the airplane over a three-day period. On the day of the accident, during the takeoff, the airplane collided with a runway light then departed the airport area. A search was initiated when the pilot did not return in a reasonable amount of time. The wreckage and the pilot were located the next morning about 1.8 nautical miles southwest of the departure airport in an area of thick trees and brush covered terrain. The pilot related to the airport caretaker that; the engine lost power due to “magneto problems.” The airplane was substantially damaged during landing. A postaccident examination of the magnetos revealed no anomalies with either magneto that would have precluded normal operation. Additionally, the fuel tank was found undamaged and empty at the accident site and there was no odor of fuel or evidence of pooling fuel from possible fuel leaks. The pilot’s reported loss of engine power was attributed to fuel exhaustion due to his failure to ensure that sufficient fuel was available for the flight prior to departure.

Probable cause

The non-certificated pilot’s failure to ensure adequate fuel onboard prior to flight, which resulted in a loss of engine power due to fuel exhaustion.

  • 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, coordinates. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 2019-01-29.
