| Executive Summary: | About 1851 EST on November 27, 1973, Delta Air Lines Flight 516, a McDonnell Douglas DC-9-32, N3323L, crashed while making an ILS approach to runway 20 at Chattanooga Municipal Airport, Chattanooga, Tennessee. Seventy-four passengers and five crewmembers were aboard the aircraft. Thirty-eight passengers and four crewmembers were injured; there were no fatalities. The aircraft struck the approach lights 1,600 feet from the runway threshold. After initial impact, the aircraft continued through the approach lights and struck a flood-control dike located 785 feet from the runway threshold. The aircraft stopped on the airport 450. feet beyond the approach end of the runway and 250 feet left of the runway centerline. The aircraft was destroyed. The National Transportation Safety Board determines the probable cause of the accident was that the pilot did not recognize the need to correct an excessive rate of descent after the aircraft had passed decision height. This occurred despite two verbal reports of increasing sink rate by the first officer. The captain disregarded the reports of the first officer, possibly because of the influence of a visual illusion caused by the refraction of light through the heavy rain on the windshield. The excessive rate of descent was initiated by a wind shear condition which existed in the lower levels of the approach path and a glide slope that tended toward the lower signal limit. |
