Narrative:A Beechcraft 200 Super King Air, N456L, owned and operated by Lufkin Industries, crashed and burned in an open field near Parker, Colorado.
About 9 1/2 minutes after departure from Denver-Arapahoe County Airport, CO (APA), the pilots of N456L declared an emergency because of airframe icing. The aircraft was being vectored to land at Denver-Stapleton International Airport, CO, when it crashed into an open field about 13 miles east of Arapahoe County Airport. The two pilots and eight passengers on board were killed in the crash and subsequent ground fire. The aircraft was destroyed.
Probable Cause:The National Transportation Safety Board determines that the probable cause of the accident was the rapid accumulation of ice on the underwing surface aft of the deicing boots which destroyed the aircraft's capability to maintain level flight because the flightcrew: failed to obtain a current weather briefing before departure; failed to make a timely decision to discontinue the climb and return to Arapahoe Airport; and operated the over-gross-weight aircraft at high angles of attack in severe icing conditions.
