This evaluation of flightline fire extinguishers has been conducted to determine minimum performance criteria for assessing the capability of fire extinguishing agents to suppress two specific aircraft engine fires three dimensional flowing fuel fires in the aircraft tail pipe and engine nacelle fires that can be fought through the access panel. This test series documented performance of 150 lb fire extinguishers containing Halon 1211 for extinguishing hidden and running fuel fires. An F-100 engine nacelle mockup was used to evaluate the full extinguishment times and amount of extinguishing agent used on a series of twenty aft engine and pool fires of 100-ft2 and ten access panel fires. The test series data was successfully used to develop a consistent, repeatable test procedure with passfail criteria for three dimensional and hidden fires through the rear engine and the access panel. The resulting document provides the performance standard for assessing alternative agents to determine suitability for use by USAF personnel in support of flightline fire extinguishers with the primary mission of rescue and fire suppression during aviation related incidents.
