Aircraft involved

Probable cause & findings

The student pilot's failure to maintain airplane control when the airplane drifted off of runway centerline and subsequently collided with a taxiway sign during a go-around.

Factual narrative

The solo student pilot reported that, during landing, the airplane floated and drifted left of runway centerline. The pilot did not feel that he could make a safe landing and decided to go-around. Full power was added and shortly there after, the airplane struck a taxiway sign. The pilot continued the climb and maneuvered the airplane in the airport traffic pattern and landed without further incident. The left horizontal stabilizer was substantially damaged. The student pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
