On November 20, 2023, about 2005 Pacific daylight savings time, a Bell OH-58A, N158TR, was substantially damaged when it was involved in an accident near Brawley, California. The pilot was not injured. The helicopter was operated as a Title 14 Code of Federal Regulations Part 137 agricultural application flight.
The pilot stated that shortly after departure, there was a sudden power surge followed by an abnormal engine noise and vibration. Believing that an engine failure was imminent, he made a turn toward flat terrain near the departure area. The engine power decayed and the pilot “bled off some of the available rotor rpm” to maneuver over an embankment. About 5 ft above ground level, he applied forward cyclic to level the skids. The pilot estimated that the helicopter “fell through” from about 4-5 ft agl before it landed hard.
The main rotor hub assembly separated from the main rotor mast after the rotor blades struck the wire strike protection fixture. The helicopter was secured for further examination.
