On August 12, 2016, about 1230 mountain daylight time, a Robinson R44 II, N247DB, sustained substantial damage following a forced landing near Gunnison, Utah. The pilot was operating the helicopter under the provisions of Title 14 Code of Federal Regulations (CFR) Part 91. The commercial pilot was not injured. The local aerial application flight departed about 1200. Visual instrument meteorological conditions prevailed, and no flight plan had been filed.

The pilot stated that a new spray system had been installed on the helicopter about 25 hours prior to the accident. He reported that a plastic piece of the newly installed system fractured in flight which resulted in spray chemicals entering the engine's induction system. The engine subsequently lost power.
