Analysis
During the landing roll, the right landing gear steel fitting welds broke, and the axle, brake, wheel, and wheel fairing separated from the airplane. The right landing gear strut dug into the sod and the airplane cartwheeled, coming to rest inverted in the center of the runway. The left wing separated from the airplane, and the vertical and horizontal stabilizers were crushed. No other anomalies were found that would have precluded normal operation of the airplane.
Factual narrative
On November 24, 2012, at 1524 central standard time, an Ironsides XS-1, N1879, nosed over on landing at Air Troy Estates Airport (WI69), East Troy, Wisconsin. The private pilot, the sole occupant on board, sustained minor injuries. The airplane was substantially damaged. The airplane was registered to and operated by the pilot under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Visual meteorological conditions prevailed at the time of the accident, and no flight plan had been filed. The local flight originated from WI69 about 1400. According to the pilot’s accident report, he made a normal landing on the grass airstrip. During the landing roll, the right landing gear steel fitting welds broke and the axle, brake, wheel, and wheel fairing separated from the airplane.
