The pilot's incorrect right rudder application during a touch-and go-landing, which resulted in a loss of directional control, runway excursion, and a collision with a runway sign.
Investigator assessment
Analysis narrative
According to the pilot, she was preparing to take off for a second touch-and-go landing and retracted the flaps and added engine power. The airplane veered left, and the pilot retarded the throttle and applied right rudder. The pilot affirmed that she "didn't supply adequate rudder," and the airplane exited the left side of the runway and impacted a runway sign. The airplane sustained substantial damage to the lower left fuselage longeron.
