Analysis

The flight instructor reported that, during an instructional flight, when the tailwheel-equipped airplane was at rotation for takeoff, it sharply veered to the left. When safe flight was not assured, the flight instructor took over control from the student pilot, and subsequently the airplane exited the runway into the adjacent grassy area. Postaccident examination revealed substantial damage to the fuselage. The flight instructor reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
