What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The airman flew the autogyro around and near the bay
Bridge W29 airport airspace practicing for his upcoming practical exam. Airman successfully touched down on runway 11 and as he was slowing down, he wanted to make sure it slowed down sufficiently to be able to exit the runway at the nearest taxiway to his right. This thought distracted him enough that he did not realize the rotors had tilted slightly to the right and he failed to counter-correct in a timely manner by moving the control stick to the left to move rotors to the left. This was a mistake and the rotor momentum caused the aircraft to tip on its side.
As the FAA filed it
THE AIRMAN FLEW THE AUTOGYRO AROUND AND NEAR THE BAY
BRIDGE W29 AIRPORT AIRSPACE PRACTICING FOR HIS UPCOMING PRACTICAL EXAM. AIRMAN SUCCESSFULLY TOUCHED DOWN ON RUNWAY 11 AND AS HE WAS SLOWING DOWN, HE WANTED TO MAKE SURE IT SLOWED DOWN SUFFICIENTLY TO BE ABLE TO EXIT THE RUNWAY AT THE NEAREST TAXIWAY TO HIS RIGHT. THIS THOUGHT DISTRACTED HIM ENOUGH THAT HE DID NOT REALIZE THE ROTORS HAD TILTED SLIGHTLY TO THE RIGHT AND HE FAILED TO COUNTER-CORRECT IN A TIMELY MANNER BY MOVING THE CONTROL STICK TO THE LEFT TO MOVE ROTORS TO THE LEFT. THIS WAS A MISTAKE AND THE ROTOR MOMENTUM CAUSED THE AIRCRAFT TO TIP ON ITS SIDE.
