Factual narrative

On March 18, 2024, about 1720 eastern daylight time, a Hughes 369D, N102SU, was substantially damaged when it was involved in an accident near Belleville, West Virginia. The commercial pilot was seriously injured. The helicopter was operated as a Title 14 Code of Federal Regulations Part 133 rotorcraft external load flight. According to the pilot, he was conducting tree trimming operations and previously completed several flights throughout the day with no abnormalities noted. During the accident flight, while trimming trees northbound above a creek, the pilot encountered some challenges with encroaching tree limbs. The pilot was assessing the feasibility of cutting the tree line safely, when he heard a loud “boom”, which was followed by the helicopter entering a rapid descent. He maneuvered toward smaller trees to minimize the impact. He briefly lowered the collective to preserve rotor rpm, and then raised the collective just before impact. The pilot said he intentionally did not release the cutting saw, hoping it would aid in cushioning the impact. The helicopter was recovered and retained for further examination.
