The airplane touched down about 1/3 beyond the approach end of Runway 28, a 5,000 footlong, asphalt runway. The PIC stated, 'as usual,' he applied 'light' braking and attempted to actuated the airplane's thrust reverser (TR) system; however, the TR handles could not be moved beyond the 'Deploy-Reverse-Idle' position. After the PIC cycled the levers two or three times, he began to apply maximum braking. A passenger in the airplane stated he looked out of the cockpit window, saw the end of the runway, and the airplane seemed like it was still moving 'pretty fast.' As the airplane approached the end of the runway, he could see smoke, which he believed was coming from the airplane's tires. He then sensed the airplane was falling. The co-pilot stated he had no memory at all of the accident flight. Review of the CVR revealed the co-pilot said that the airplane was 'Vref plus about twenty,' when the airplane was 100 feet over the runway threshold. The PIC could not recall the airplane's touchdown speed, however, he stated that it seemed like the airplane was still traveling 50 to 60 knots when it departed the end of the runway. A pair of parallel tire marks were observed 3,200 feet beyond the approach end of the runway. The tire marks extended past the end of the runway and onto a 106 foot-long grass area. The airplane came to rest on a plateau about 90 feet below the runway elevation. Examination of the airplane, including the optional TR system did not reveal any pre-impact malfunctions. The airplane's estimated landing distance was calculated to be about 3,100 feet. The PIC reported about 4,700 hours of total flight experience, of which, 107 hours were in make and model. The PIC stated he had never performed a landing in the accident airplane without using the TR system. Winds reported at the time of the accident were from 290 degrees at 15 knots, with 21 knot gusts.

Aircraft was dispatched with inoperative airframe deice system, tho an operational deice system was required for flight in known icing conditions. During descent to land, aircraft encountered light icing conditions. Capt believed aircraft could 'handle it' and continued descent. As he began ILS final approach, he noted significant increase of ice accumulation and used higher than normal approach speed. As full (50°) flaps were set, aircraft began buffet and pitched nose down. Capt corrected with full back pressure on control column, but aircraft landed hard, gear collapsed and aircraft slid about 3,600 feet to a stop. No preimpact mechanical anomaly was found, except for inoperative deice system. Investigation revealed pilots had received printout of weather from company computer system with surface observation and terminal forecast, but no area forecast (FA). Pilots and ground personnel were not aware that FA was available at company weather terminal. FA forecasted light and occasional moderate rime and mixed icing in clouds and precipitation above freezing level. Weather deteriorated, but pilots did not require inflight weather info or pireps. Flight mnl noted tailplane ice may cause nose down trim change with flap extension. There was evidence of tail plane stall, lack of company training in cold weather operations, deficiencies in use of deicing systems, and lack of FAA surveillance.

On approach to Beckley-Raleigh County Airport, the pilot encountered foggy conditions. During the last segment, the twin engine airplane struck a steel reinforced concrete wall and crashed in flames. The aircraft was destroyed and all six occupants were killed.
