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
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 starvation
DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative

The pilot had flown the experimental airplane once previously for less than one hour. He took off on the active runway, and was one third the way down the 5,048-foot runway at an altitude between 150 to 200 feet when the engine sputtered and surged. The pilot lowered the nose to best glide airspeed when the engine began to run again. The pilot reestablished a climb attitude in order to gain altitude and to try to assess the situation. He elected to do a 180-degree turn and land on the departure runway in the opposite direction. The engine again lost power, and the pilot initiated a turn to line up with the runway. The airplane impacted at the intersection of two runways and slide off the runway onto the grass. The builder did not use an engine driven fuel pump as drawn in the experimental airplane schematics, but utilized an electric fuel pump with an on/off switch in the cockpit. The builder stated that he had briefed the pilot on his earlier flight on the utilization of the electric fuel pump for take off. The pilot could not recall if he used the electric fuel pump.

Probable cause

The pilot's failure to select the electric fuel boost pump during take off which resulted in loss of engine power due to fuel starvation and the subsequent forced landing. A factor to this accident was the owner/builder alteration of the fuel system by installing electric fuel pump instead of a engine driven pump as depicted in the airplane's schematics.

  • 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.
