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
Maneuvering
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 control in flight
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
Destroyed

NTSB narrative

According to the passenger, the pilot said the 'impossible turn' was not impossible and that he would demonstrate. The pilot pulled back the throttle and made a 20 degree left bank without lowering the nose. The airplane stalled and 'porpoised' to the ground. According to the pilot, at an altitude between 700 and 900 feet agl, he reduced power 'a few hundred' rpm to simulate a power loss, and lowered the nose. The stall warning sounded and the airplane entered a right spin. The pilot was able to recover, but the airplane entered a left spin. The pilot was again able to stop the spin, but the airplane 'wobbled' and collided with terrain.

Probable cause

An inadvertent stall spin. Factors were the pilot's intentional maneuver at an altitude insufficient to ensure a safe recovery, and overconfidence in his personal ability.

  • 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 1996-06-24.
  • API snapshot SHA-256: 3db4b6f2a10926c382179f334c96a5432451e525eee86f37e2410548d9370951; retrieved 2026-09-21T21:44:26.028Z.
