Investigations, on-the-scene studies of aircraft accidents, and some helicopter drop-crash tests have been made in an effort to establish the severity of crash impact for which crash-resistant flammable fluid systems, installed in fuselages of fixed- and rotary-wing aircraft, should be designed. These investigations, studies, and tests reveal that post-crash fire is a major factor contributing to higher fatality rates during aircraft accidents, and that a crash-load factor in the order of 35 may be considered likely under severe but survivable crash conditions. There are certain particular locations in the aircraft where fuel tanks would not be located unless means for affording them substantial protection against damage in crashes is provided.
