What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
When Aircraft reached a speed of an estimated 40 - 45 knots, the Aircraft exicuted an un-commanded left turn. Pilot closed the throttle and applied full right rudder along with heavy right pedal braking neither of which could arrest the dramatic swerve to the left. The Aircraft departed the runway at an angle of about 60° to the runway centerline. The pilot applied full right and left braking to avoid contacting the drainage ditch. The Aircraft stood up on its nose and the starboard wing tip continuing on over coming to rest upside down.
