Aircraft involved

Probable cause & findings

The student pilot’s failure to maintain directional control during landing after touching down with the left brake engaged. Contributing to the accident was the flight instructor’s delayed remedial action.

Factual narrative

The flight instructor reported that, during a training flight, upon landing, the tailwheel-equipped airplane bounced slightly. Subsequently, when the airplane touched back down it veered to the left. He added that, the student did not react immediately, so he added power and right rudder to correct. The airplane exited the left side of the runway, he added full right brake to avoid a visual approach slope indicator (VASI) light, and the airplane ground looped to the right. The flight instructor added that the student had apparently touched down after the first bounce with the left brake engaged. The airplane sustained substantial damage to the left wing and aileron. The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
