What happened
A single-engine aircraft, carrying two pilots, two passengers, and various equipment, was performing a diversion to an alternative airport due to the presence of icing conditions. During the descent while executing a left turn from the base leg to the final approach for runway 22, the aircraft lost altitude and impacted the ground. Following the initial impact, the plane slid approximately 250 feet, during which time the wings were severed by two trees.
The accident resulted in two fatalities among the crew and two serious injuries among the passengers. Post-accident analysis confirmed the engine was functional and had completed a satisfactory run-up prior to the event.
Findings
Investigations into the accident revealed several critical weight and balance discrepancies. At the time of takeoff, the aircraft was 955 pounds above its maximum allowable gross weight and positioned 2 inches beyond the aft center of gravity limit. Furthermore, during the landing phase, the aircraft was approximately 600 pounds over its maximum landing weight and remained 2 inches beyond the aft center of gravity limit.
Environmental factors and improper configuration also contributed to the crash. The aircraft was operating in light freezing rain, a condition the pilot's operating handbook advises avoiding. Additionally, the air induction lever was left in the primary position rather than the required alternate position for icing conditions. The propeller and stall warning heat switches were also found to be in the off position.
