The report is concerned with the determination of the performance of fire detection systems in USAF aircraft. Data on false fire warnings and aircraft engine nacelle fires were taken from Air Force accident/incident reports. These data included the time period 1965 through 1970 and is restricted to noncombat related accidents/incidents. Analysis of the data showed that false fire warnings are a major problem in the majority of USAF aircraft (83% of all reported alarms are false). These false fire warnings resulted in damage or destruction ot aircraft as well as crew injuries/fatalities. In addition, it was found that in approximately 50% of the engine nacelle fires, where the performance of the detection system could be determined, the system did not provide an alarm. It was also found that the fire detection system in a number of aircraft had been partially or totally removed to reduce or eliminate the false fire warning problem. As a consequence the majority of the fires which occurred in these aircraft were not detected. (Author)
