It continued until encountering a swampy area at which time the nose wheel dug in, and the airplane nosed over. The left wing strut and wing sustained substantial damage. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative The pilot reported that the airplane landed on centerline, immediately pulled to the left, and quickly left the runway.
