Flight Details
The single-engine airplane departed with two pilots, two passengers, baggage, and equipment. At takeoff, the airplane was 955 pounds over the maximum allowable gross weight and 2 inches beyond the aft center of gravity (CG) limit.
Diversion and Icing Conditions
After approximately four hours of flying, the pilot elected to divert to another airport due to icing conditions. The airplane had been flying in light freezing rain, which the Pilot's Operating Handbook (POH) stated should be avoided. Severe mixed icing was reported 25 miles northwest of the airport.
Accident Sequence
During the descending left turn from base leg to final approach for Runway 22, the airplane dropped, struck the ground, and slid 250 feet. The wings separated from the airplane during the ground slide after contacting two trees.
Aircraft Configuration and Performance
At the time of the accident, the airplane was calculated to be approximately 600 pounds over the maximum landing weight, and 2 inches beyond the aft CG limit. The air induction lever was found in the primary position, not the required alternate position for icing conditions. Additionally, the propeller and stall warning heat switches were off.
Post-Accident Examination
A satisfactory postaccident engine run was completed. Winds at the airport were from 150 degrees at 10 knots, gusting to 16 knots.
