Flight Conducted Under: Part 91: General aviation - Banner tow


The pilot reported that he had completed a banner tow flight and had dropped the banner at its designated location.

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.
