Aircraft: Cessna 182. Injuries: 1 Fatal, 1 Serious. Location: Black Hawk, Colo. Aircraft damage: Destroyed.
What reportedly happened: The pilot had filed and activated an instrument flight plan. During the flight the airplane entered clouds and snow showers. The temperatures, compounded with relative humidity, placed the airplane in conditions favorable for structural and induction system icing. The engine lost power and the pilot could not maintain level flight. The airplane began to descend. During the descent, the engine surged. The pilot continued to maneuver the airplane until it hit terrain.
Probable cause: The loss of engine power due to induction icing. A contributing factor was the pilot’s decision to continue flight in conditions favorable for structural and induction-system icing.
