Factual narrative

THE AIRCRAFT WAS OBSERVED TO ENTER A LEFT DOWNWIND FOR RUNWAY 4 AT AN ALTITUDE OF APPROXIMATELY 2000 FT AGL. AT ABOUT THE MID-FIELD POINT, THE POWER WAS REDUCED. A WITNESS RPRTD THE ACFT WAS TOO HIGH TO LAND & THE PLT INITIATED A LEFT TURN TO SPIRAL DOWN. DURING THE SPIRAL, POWER WAS INCREASED AND THE AIRCRAFT ENTERED A SPIN. SUBSEQUENTLY, IT CRASHED ABOUT 150 YARDS SHORT OF THE APPROACH END OF RUNWAY 4. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
