The Bell UH-1B, N41870, collided with trees during a forced landing near Ozark, Alabama. The helicopter was operated by Summit Helicopters, Inc. under the provisions of 14 CFR Part 91, and visual flight rules. A flight plan was not filed for the positioning flight. There were no injuries to the commercial pilot, minor injuries to a passenger, and substantial damage to the aircraft. Origination of the flight was Brantley, Alabama, about 1615, on the same day.
The pilot reported that while in cruise flight, the engine chip light illuminated. About five seconds later it extinguished. Since the helicopter was about three miles from the Blackwell Airport, Ozark, Alabama, he elected to continue toward the airport. The chip light re-illuminated and the pilot began searching for a landing site in the heavily wooded terrain. About the same time, the low rotor speed warning horn sounded. An autorotation was established to an open field. The helicopter could not reach the field and collided with trees.
Metal debris was found in the accessory gearbox during a post accident, on-site inspection of the engine. Subsequently, a teardown and inspection of the engine was performed. The number one, three, and four bearings had failed because of a lack of lubrication.
