Abstract : The Federal Aviation Administration (FAA) Western Pacific Regional Office issued a Significant Activity Report concerning a 5727 that experienced extensive corrosion, well beyond what would have normally been expected for an aircraft with its operational time and cycles. This incident triggered interest in the possible connection between fire, extinguishment, and subsequent increased incidence of corrosion. The FAA Technical Center requested an investigation of the potential for this connection to exist by performing an analysis of available data. Trends of aircraft operational hours, cycles, fire occurrence, and corrosion reports were developed. Data extending from 1974 to the present were accessed from the Aviation Research and Support database and the Service Difficulty Reports (SDRs) database, respectively. Sufficient data to support a connection between fire and subsequent related corrosion were not available. Twenty-two aircraft were analyzed and none exhibited a pattern of corrosion that could definitely be associated with fire smoke or extinguishment. This result was supported by consideration of the intensity of the fire, the extinguishing agent and the time between the occurrence of the fire and the corrosion reports. jg
