The NTSB's narrative final · quoted from the NTSB record

A WITNESS REPORTED THE AIRPLANE WAS DOING AEROBATIC MANUEVERS WHEN IT CRASHED. ACCORDING TO A WITNESS, THE AIRPLANE WAS ABOUT 2000 FEET MSL WHEN HE SAW THE AIRPLANE ROLL TWO AND ONE HALF TIMES, FINISHING IN AN INVERTED ATTITUDE. THE AIRPLANE THEN ENTERED A FLAT SPIN BEFORE IT PITCHED DOWN AND DESCENDED. THE WITNESS STATED THE AIRPLANE STOPPED SPINNING AND WAS BEGINNING TO LEVEL WHEN IT COLLIDED WITH THE GROUND. THE INVESTIGATION DID NOT REVEAL EVIDENCE OF AIRCRAFT MECHANICAL MALFUNCTION. THE PILOT AND PASSENGER WERE SERIOUSLY INJURED AND DID NOT RECALL THE DETAILS OF THE FLIGHT.
