Accident Summary
The pilot was executing his third touch-and-go of the flight when the accident happened. On approach, the flaps were fully extended. The approach was "slightly" steeper, and 2 to 3 knots faster than the previous approaches. Yoke back pressure was added, and the airplane climbed 2 to 3 feet higher. Fearing a hard landing, the pilot initiated a go-around, but before he could react, the airplane landed hard with a small bounce.
Sequence of Events
After the bounce, and while the airplane was rolling unstabilized down the runway, the pilot continued with the go-around. He was not sure if he advanced the throttle and retracted the flaps, or vice versa. He did remember not re-trimming the airplane for takeoff, or applying full right rudder when the airplane started to drift left.
Outcome
While partially airborne, the airplane exited the left side of the runway, and the pilot aborted the go-around. The nose wheel contacted the ground, and the airplane nosed in.
Additional Information
The pilot reported the winds as "mostly calm." In addition, he made no mention of any mechanical failures or malfunctions with the airplane.
