Southern Airways flight 932, a DC-9-30, crashed while on approach to Huntington-Tri-State Airport, West Virginia, USA, killing all 75 occupants. Flight 932 departed Kinston, North Carolina, USA at 18:38 to return members of the Marshall University football team, coaching staff and other passengers to Huntington, West Virginia. After an uneventful flight, the crew contacted Huntington Approach Control at 19:23. The controller later cleared them for a runway 11 localizer approach. At 19:34 the flight passed the Outer Marker and they were cleared to land. In weather conditions of mist and light rain with low clouds (scattered clouds at 300 feet, broken overcast at 500 feet solid overcast at 1000 feet), the aircraft descended below MDA (1240 ft msl) while the flight crew still not had the runway environment in sight. The aircraft then and struck trees on a hill at an elevation of 922 ft msl, approximately 1 mile short of the runway. The aircraft then crashed and caught fire. PROBABLE CAUSE: “The descent below Minimum Descent Altitude during a non precision approach under adverse weather conditions, without visual contact with the runway environment. The Board has been unable to determine the reason for this descent, although the two most likely explanations are: a) improper use of cockpit instrument data; or b) an altimetry system error.”
