Primary finding
Probable cause
The pilot's failure to maintain directional control of the airplane during the landing roll, which resulted in a runway excursion and nose-over.
Investigator assessment
Analysis narrative
The pilot reported that he had completed a banner tow flight and had dropped the banner at its designated location. He subsequently entered the traffic pattern and approached to land with a right crosswind. During the landing roll, the airplane weather-vaned, exited the right side of the runway, and entered soft grass. The airplane nosed over, which resulted in substantial damage to the left upper wing, vertical stabilizer, and rudder. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Factual narrative
The pilot in the tailwheel-equipped biplane had completed a banner tow flight and had dropped the banner at its designated location. He subsequently entered the traffic pattern and approached to land with a right crosswind. During the landing roll, the airplane weathervaned, exited the right side of the runway and entered the soft grass surface that bordered the runway. The airplane nosed over and sustained substantial damage to the left upper wing, the vertical stabilizer and the rudder. The pilot reported no preaccident anomalies with the airplane that could have contributed to the accident. The pilot reported that about the time of the accident, the wind was from 360° at 8 knots. The airplane landed on runway 33.
