The pilot reported he had been practicing touch and go landings and that the accident occurred on the 11th landing of the flight. He reported the airplane touched down and was rolling out on the centerline when it suddenly veered to the right. He reported he was unable to straighten out the heading and the airplane traveled off the side of the runway into the grass. The local winds were from 090 degrees at 4 knots. Inspection of the airplane revealed the weld which attached the left main landing gear strut to the airframe had failed. ## Factual narrative The airplane was substantially damaged during a ground loop while landing on runway 09.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. - [NTSB CHI04CA226](https://openairdocs.org/ntsb/CHI04CA226), Aug 14, 2004: Devereux Mustang II (N44DX), Elkhart, IN, substantial damage. Probable cause: The pilot not maintaining directional control during landing roll. A factor was the soft terrain, and the inadequate training in type aircraft. From the NTSB's public API.
