The NTSB's narrative final · quoted from the NTSB record
THE ACFT ACCELERATED OVER THE RUNWAY AFTER A 10 SEC HOVER. AFTER ACCELERATION, THE ACFT WENT INTO A NOSE HIGH, STEEP, RIGHT CLIMBING TURN. THE ANGLE OF BANK WAS DESCRIBED AS 45 TO 90 DEG. THE PITCH VARIED FROM 15 DEG UP TO 30 DEG DOWN JUST PRIOR TO IMPACT. MAX ALT WAS ESTIMATED TO BE 75 TO 200 FT AGL. THE NOSE DROPPED THROUGH AFTER 90 DEG OF TURN. THE DESCENDING RIGHT TURN CONTINUED UNTIL GROUND CONTACT. WITNESSES REPORTED THAT A RECOVERY WAS APPRARENTLY STARTED JUST PRIOR TO IMPACT. THIS TYPE OF MANEUVER WAS PREVIOUSLY USED IN DEMONSTRATIONS DURING UPGRADE TRAINING, BUT NOT IN WINDS THAT EXISTED ON THE DAY OF THE ACCIDENT. ACCORDING TO AN MBB REPORT, THE MANEUVER (AS DESCRIBED) WAS CONSIDERED DANGEROUS. NO MALFUNCTIONS OF THE AIRCRAFT WERE FOUND. BOTH PLTS AND VERY LITTLE EXPERIENCE IN THE BO-105.
