Analysis
The flight instructor reported that he was providing flight instruction to the pilot who had recently purchased the tailwheel-equipped airplane, and during takeoff, a crosswind pushed the airplane to the left. He attempted to correct for the left drift to no avail. Subsequently, the airplane continued to the left, exited the runway, impacted a snowbank, and nosed over, resulting in substantial damage to the wings. The flight instructor reported that there were no preaccident mechanical malfunctions or anomalies that would have precluded normal operation.
