The NTSB's narrative final · quoted from the NTSB record
THE PILOT HAD COMPLETED SEVERAL TOUCH & GO LANDINGS. DURING THE LAST LANDING, THE RIGHT WING WAS LIFTED BY A CROSSWIND GUST. RIGHT AILERON WAS APPLIED WITHOUT EFFECT. SINCE THE AIRPLANE WAS IN THE LANDING FLARE, THE AIRSPEED WAS TOO SLOW FOR RUDDER EFFECTIVENESS. FULL POWER HAD ALREADY BEEN APPLIED FOR THE GO-AROUND, SO THE AIRPLANE VEERED LEFT. THE LEFT WHEEL STRUCK A BERM WHICH CATAPULTED THE AIRPLANE ONTO ITS NOSE. THE OWNER/BUILDER SUBSEQUENTLY FOUND THAT THE CONTROL STICK HAD SEPARATED FROM THE AILERON BELLCRANK. HE HAD SUBSTITUTED THE STICK FOR THE CONTROL WHEEL, ATTACHING THE AILERON BELLCRANK TO THE STICK WITH RIVETS. THE RIVETS HAD SHEARED WHICH RESULTED IN A LOSS OF AILERON CONTROL.
