Pilot Attempted To Adjust The Engine Power Settings, But The Engine Power “Went To Low Power And Was Not Responding To Throttle Control Inputs.”
Analysis: After takeoff the pilot performed a practice RNAV approach, then climbed to 3,500 ft mean sea level en route to another airport. While at altitude the pilot attempted to adjust the engine power settings, but the engine power “went to low power and was not responding to throttle control inputs.” He declared an emergency and after realizing that the flight was unable to reach a nearby airport, he selected a nearby field with a paved road.
