16. Abstract Southern Airways Inc., DC-9, Np7S, operating as charter Flight 932, crashed during a landing attempt at the Tri-State Airport, Huntington, West Virginia, at approximately 1936 e.s.t. on November 14, 1970. All 75 occupants, including 71 passengers and four crewmembers, were fatally injured. The aircraft was destroyed. The flight, chartered to transport the Marshall University football team and boosters from Kinston, North Carolina, to Huntington, West Virginia, was attempting a nonprecision instrument landing approach to Runway 11 at the time of the accident. The crash occurred following impact with trees on a hill approximately 1 mile west of the runway threshold. The elevation of the broken trees at the initial impact site was approximately 922 feet m.s.l. The National Transportation Safety Board determines that the probable cause of this accident was the descent below Minimum Descent Altitude during a nonprecision approach under adverse operating 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 instruction data, or (b) an altimetry system error. | |||
17. Key Words Aircraft accident, character operation, crew coordination, misuse of altitude information, vertical guidance in nonprecision approaches. |
