| Executive Summary: | On September 8, 1989, N283AU, a Boeing 737-200 operated as USAir flight 105 was a regularly scheduled revenue passenger flight conducted under 14 Code of Federal Regulations Part 121 from Pittsburgh, Pennsylvania, to Wichita, Kansas, with an en route stop in Kansas City, Missouri. Fifty-eight passengers, two flight crewmembers and four flight attendants were onboard. A Federal Aviation Administration inspector who was performing an en route inspection occupied the cockpit observer's seat. The flight from Pittsburgh to the Kansas City area was uneventful. The captain was the pilot flying and the first officer was performing the , communications with air traffic control. USAir 105 was cleared to execute the localizer back course approach to runway 27 at 2129:41. At 2134:23, the local controller told USAir 105 "I can't tell for sure but it appears we have lost the lighting on the south side of the airport." The flightcrew later described seeing a bright flash about this time. Subsequent inspection revealed that the airplane struck and severed four electronic transmission cables, located about 75 feet above the ground, approximately 7,000 feet east. of the runway 27 threshold. The flightcrew executed a missed approach and landed uneventfully in Salina, Kansas. None of the passengers or crew was injured, but the airplane sustained minor damage in the incident. The National Transportation Safety Board determines that the probable cause of this incident was the flightcrew's failure to adequately prepare for and execute a nonprecision approach and their subsequent premature descent below minimum descent altitude. Contributing to the cause of the incident was the inadequate and deficient services provided to the flightcrew by air traffic control personnel. The safety issues raised in this report include: o Identification of potentially confusing features near runways on instrument approach charts. o FAA oversight of air traffic control quality assurance. o FAA training of and guidance to operations' inspectors. o Application of visual descent points to training in and execution of nonprecision instrument approaches, and incorporation of requirements for visual descent points in FAR Part 135 operations. o Communication of weather information between air traffic control and the National Weather Service. o Revision of minimum safe altitude warning inhibit areas. |
