Factual narrative

THIS WAS AN EXPERIMENTAL AMATEUR-BUILT ACFT. WITNESSES REPORTED SEEING THE ACFT IN A STEEP RIGHT BANK WHEN THE ENG LOST POWER. THE ACFT WAS THEN SEEN TO STALL AND ENTER A RIGHT SPIN. WITNESSES SAID THE PLT RECOVERED BUT ENTERED A SECOND STALL AND DOVE STRAIGHT INTO GROUND. NO EVIDENCE OF AIRFRAME, ENG, PROP, OR FLT CONTROL MALFUNCTION/FAILURE WAS FOUND. ENG WAS LATER FUNCTIONALLY TESTED AND RAN NORMALLY. PLT HAD NEVER BEEN GIVEN INSTRUCTION IN STALL/SPIN RECOVERY. PLT HAD LOGGED 7 HRS IN ACFT AND WAS MAKING 5TH FLT WHEN ACCIDENT OCCURRED. DENSITY ALTITUDE WAS COMPUTED TO BE 8157 FT MSL. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
