- 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
- Partial loss of engine power (mechanical failure)
- 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/mush
- 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
- Eng assembly, crankshaft counterweights/vib damper › Separation
- Pilot in command › Airspeed(vso), not maintained

NTSB narrative
AFTER TAKEOFF ABOUT 250 FEET MSL, THE ENGINE EXPERIENCED NEAR TOTAL LOSS OF POWER. THE PILOT INITIATED A TURN TO LAND ON A BEACH BUT IT WAS NOT SUITABLE. HE THEN INITIATED A TURN TO LAND DOWNWIND BUT THE AIRPLANE STALLED WHEN THE FLIGHT WAS ABOUT 100 FEET ABOVE GROUND LEVEL. THE AIRPLANE IMPACTED THE RUNWAY NOSE AND LEFT WING LOW WHICH COLLAPSED THE NOSE AND LEFT MAIN LANDING GEARS. EXAMINATION OF THE FLIGHT CONTROLS REVEALED NO EVIDENCE OF PREIMPACT FAILURE OR MALFUNCTION. EXAMINATION OF THE ENGINE REVEALED THAT ONE OF THE TWO COUNTERWEIGHTS SEPARATED FROM THE CRANKSHAFT FOR UNDETERMINED REASONS. THE AIRCRAFT, ENGINE, AND PROPELLER LOGBOOKS WERE NOT LOCATED. THE OWNER STATED THAT THE ENGINE WAS OVERHAULED IN JAN. OR FEB. 1993 BY AN A & P MECHANIC WHO HAS INSPECTION AUTHORIZATION. AT THE TIME OF THE ACCIDENT, THE ENGINE HAD ACCUMULATED ABOUT 100 HOURS SINCE OVERHAUL. REVIEW OF PAPERWORK PROVIDED BY THE PILOT REVEALED THAT COUNTERWEIGHT HARDWARE ( TWO EA LOCK RINGS, FOUR EA PINS, & EIGHT EA BUSHINGS) WAS ORDERED AND SHIPPED TO PRECISION ENGINE IN WASHINGTON, NC, ON FEB. 1, 1993.
Probable cause
THE PILOT'S FAILURE TO MAINTAIN AIRSPEED (VSO) RESULTING IN A STALL/MUSH. CONTRIBUTING TO THE ACCIDENT WAS THE NEAR TOTAL LOSS OF ENGINE POWER DUE TO SEPARATION OF ONE OF THE TWO COUNTERWEIGHTS FOR UNDETERMINED REASONS.

- 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.
