- 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
- Loss of engine power
- 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
- Stall/spin
- 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
SHORTLY AFTER TAKE OFF, THE EXPERIMENTAL HOMEBUILT AIRPLANE WAS OBSERVED TO HAVE REACHED 150 FT AGL WHEN THE ENGINE BEGAN TO SPUTTER. THE ENGINE REGAINED FULL POWER MOMENTARILY; HOWEVER, WHEN THE AIRPLANE BEGAN A LEFT TURN, THE ENGINE SPUTTERED AND QUIT. THE AIRPLANE CONTINUED THE LEFT TURN WHICH INCREASED TO A SPIN. THE AIRPLANE THEN COLLIDED WITH THE TERRAIN IN A NOSE DOWN LEFT WING LOW ALTITUDE. DURING THE ENGINE EXAMINATION THERE WERE NO NOTED MECHANICAL FAILURES OR MALFUNCTIONS. AIRPLANE DOCUMENTATION SUGGESTS THAT BOTH AN ENGINE DRIVEN FUEL PUMP AND AN ELECTRICAL AUXILIARY FUEL PUMP BE INSTALLED. THE PILOT HAD INSTALLED ONLY AN ELECTRIC FUEL BOOST PUMP.
Probable cause
THE PILOT'S FAILURE TO MAINTAIN AIRSPEED DURING TAKEOFF FOLLOWING AN ENGINE LOSS OF POWER. THE REASON FOR THE LOSS OF POWER WAS NOT DETERMINED.

Source notes (4)
- 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 1990-08-12.
- API snapshot SHA-256: 4efc5ff221a71b53200757fea73dcecc28a0da7bc46a5d7a45338bc124c6f251; retrieved 2026-09-21T02:22:29.687Z.
