Probable cause

The student pilot's failure to maintain directional control. A factor related to the accident was: the taxiway marker's lack of frangibility due to its construction.

Analysis

The student pilot reported that after he applied power to takeoff from a touch and go landing, he lost directional control and aircraft collided with a taxiway informational sign. The aircraft incurred substantial damage; however, the sign, which was located at the edge of the runway safety area, sustained only minimal damage. The four by four supports, which had been cross drilled by airport maintenance personnel, failed to break away.
