Preliminary report

What NTSB knew early in the investigation. It may change in the final report.

On April 14, 2025, about 1800 Pacific daylight time, a Bell 206B, N16671, was substantially damaged when it was involved in an accident near Amboy, Washington. The pilot was not injured. The helicopter was operated as a Title 14 Code of Federal Regulations, Part 91 personal flight. The pilot reported that he had been operating the helicopter for about one hour, practicing takeoff and landings. While about 800 ft above ground level (agl), he felt a shudder and heard the engine sounding differently, followed by the engine chip detector light illuminating and the engine losing power. He entered an autorotation, turned right to an open field, and landed with about a 20-knot tailwind. During the landing sequence, the tail skid contacted the ground initially followed by the tailboom separating near the elevators. The helicopter came to rest balanced on the right skid, right elevator and one main rotor blade. The helicopter sustained substantial damage to the tailboom. A visual examination of the engine revealed damage to the compressor section. The helicopter was recovered to a secure facility for further examination.
