Factual narrative
THE COMMERCIAL PLT WAS PERFORMING HOVER TESTS IN HIS EXPERIMENTAL HELICOPTER AT HIS PRIVATE HELIPAD, LOCATED 60 FEET FROM HIS RESIDENCE. THE PLT REPORTED WINDS AS VARIABLE GUSTING TO 40 KNOTS. THE PLT'S ATTENTION WAS DIVERTED AND A WIND GUST PUSHED THE HELICOPTER INTO THE PORCH. THE THREE MAIN ROTOR BLADES WERE SEVERED AT IMPACT. THE HELICOPTER PIVOTED TO THE LEFT AND SETTLED ON ITS NOSE AD LEFT SIDE IN SHRUBS. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
