As the pilot leveled the Cessna 206 at 2,500 feet mean sea level during the descent for landing, he advanced the throttle but observed no response from the engine.
He could not restore engine power, however the propeller continued to spin.
He noted that the throttle “felt very loose” when he attempted to add power.
The airplane was unable to maintain altitude, so he performed a forced landing in a field near Wiggins, Miss..
The airplane collided with trees before coming to rest in the field, which resulted in structural damage to the airframe and minor injuries to the three occupants.
During a post-accident examination of the airframe and engine, the portion of the engine throttle cable that was normally clamped just forward of the upper right engine firewall was found forward of and unclamped from its clamping device.
It is likely that the throttle cable became unsecured during the flight and led to the lack of throttle response reported by the pilot.
The NTSB determined the probable cause as a loosening of the engine throttle cable from its support clamp during flight, which resulted in a loss of throttle control.
