## Preliminary report

On July 8, 2025, about 1840 Pacific daylight time, a Beech A36, N41VH, was substantially damaged when it was involved in an accident near Coolin, Idaho. The pilot and passenger sustained minor injuries. The airplane was operated under Title 14 Code of Federal Regulations Part 91 personal flight. According to the pilot, while departing from Cavanaugh Bay Airport (66S) Coolin, Idaho, the right wing contacted a tree at the end of the runway, and the airplane rolled over and came to rest in a lake located just off the end of the runway. The airplane sustained substantial damage to the fuselage and wings. Witnesses to the accident reported they heard the engine running at a “high RPM” and saw the airplane make a steep right bank on the departure end of the runway before the right wing struck trees. Density altitude at the time of the accident was calculated to be about 5,267 ft. The wreckage was retained for further examination.
