## Preliminary report

On October 4, 2025, about 2130 central daylight time, a Lancair 320 airplane, N431M, was destroyed when it was involved in an accident near Huron, Indiana. The pilot was seriously injured. The airplane was operated under Title 14 Code of Federal Regulations as a Part 91 personal flight. The pilot stated that during cruise flight at 4,500 ft, the engine stopped producing power without any warning. He attempted to restore engine power by increasing the mixture control to the fully rich position, adjusting the throttle position, and turning on the electric fuel pump. He was unable to maintain altitude and executed a forced landing into trees. The airplane was destroyed when it impacted trees. The airplane was retained for further examination.
