Aircraft involved
Factual narrative
THE ACFT COLLIDED WITH THE GROUND IN A VERTICAL NOSE DOWN ATTITUDE. THE ENGINE WAS IMBEDDED 4 FT INTO THE GROUND. ALL COMPONENTS OF THE ACFT WERE ACCOUNTED FOR IN THE IMMEDIATE AREA OF THE IMPACT. WITNESSES OBSERVED THE ACFT IN A LEFT TURN BEFORE FALLING INTO A LEFT SPIN FOR 3/4 TURN AND STRIKING THE GROUND IN A VERTICAL ATTITUDE. A BURST OF ENGINE POWER WAS HEARD PRIOR TO IMPACT. A LOCAL PILOT WHO HAD FLOWN WITH THE OPERATOR IN THE ACCIDENT ACFT 2 WEEKS PRIOR TO THEMISHAP NOTED THAT THE AIRSPEED WAS READING ABOUT 15 MPH HIGH WITH INCIPIENT STALL CHARACTERISTICS NOTED WHEN AIRSPEED READINGS AS HIGH AS 70 MPH. THE OWNER STATED HE WOULD HAVE THE INSTRUMENT RECALIBRATED. NO EVIDENCE OF THIS WORK BEING DONE WAS FOUND. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
