NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot was receiving instruction in the tailwheel-equipped airplane. He reported that, during the landing roll, the airplane turned left and that he “over corrected with too much right rudder.” He added that the airplane ground looped, exited the runway to the right, and came to rest in a nose-down attitude. 

The airplane sustained substantial damage to the firewall.

The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot receiving instruction’s overcorrection with rudder during the landing roll, which resulted in a ground loop and runway excursion. Contributing to the accident was the flight instructor’s delayed remedial action.
