Incident Overview
A student pilot was practicing touch-and-go landings when, during one landing, the power was inadvertently left on. During the landing rollout, the student was unable to maintain directional control of the aircraft. The airplane began to move left and right across the runway. The student reported that he began to overcorrect in an attempt to keep the aircraft on the runway centerline rather than reducing the power. The aircraft subsequently departed the runway edge and struck a distance marker sign.
Aircraft Examination
An examination of the aircraft was conducted following the incident; no abnormalities with the aircraft were noted.
Conclusion
No probable cause was stated in the investigation source.
