The pilot further reported that the airplane was close to the left runway edge, so he allowed the airplane to continue off the runway, in effort not to overcorrect to the right. During the runway excursion, the right main landing gear collapsed in soft terrain. The right wing sustained substantial damage. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative The pilot of the multi-engine tailwheel-equipped airplane reported that during the landing roll, after the tailwheel had touched down, the airplane veered sharply to the left.
