What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
During departure, while performing a soft-field takeoff, a bump was felt by the PIC from the left main gear and a very sudden and hard turn to the left. Directional control along the vertical axis was lost, resulting in the aircraft veering to the left. Full right rudder was applied and engine power was reduced by the PIC in an attempt to counteract the left-turning tendencies. These corrective actions were insufficient to maintain directional control of the aircraft.
