Precursors

Two previous accidents, UAL DC-8 in July 1961 and TWA B-707 in November 1964, indicated that the existing regulations relating to occupant survival and passenger evacuation were not adequate. After these two accidents, the FAA was aware of the need to upgrade the regulations in the emergency evacuation and cabin safety areas, and was evaluating regulatory changes when the UAL 266 accident occurred. This accident prompted quicker action and led to Amendment 25-15 which changed many cabin safety regulations.
