Narrative:
On February 1, 2020, about 1400 mountain standard time, a Hiller UH-1E helicopter, N7173S, was substantially damaged during a forced landing near Dinosaur, Colorado. The pilot and two passengers were not injured. The airplane was registered to Craig Helicopters Inc. and operated by Dynamic Aviation Helicopter Service as a Title 14 Code of Federal Regulations Part 135 air taxi flight. Visual meteorological conditions prevailed at the time of the accident. The local flight departed without a flight plan from Vernal Regional Airport (VEL), Vernal, Utah about 1315.

According to the pilot, the purpose of the flight was to search for lost cattle. While in level flight about 700 ft above ground level, the pilot heard a grinding noise for about three seconds, followed immediately by a loss of power. The pilot conducted an autorotation to a forced landing, during which the tail boom was damaged. The helicopter was retained for a future examination.
