Abstract:

U.S. Army risk management is a process used to minimize loss of life, injuries, and property damage. One step in the risk management process is risk assessment. Currently, risk assessment assigns a probability value for an identified hazard, based on a subjective evaluation. The need exists to assign objective probability values when assessing the risks imposed by aircraft component and part failures. This research extracted UH-60 and UH-1 helicopter part failure data for a 10-year period from the Army Safety Management Information System ASMIS data base. Data inconsistencies were corrected, the corrected data were organized into groups, and failure rates were calculated. The results established that component and part failure analyses can be successfully conducted using available data bases and that these data can be used to quantify hazard probabilities for failed aircraft components and parts. Volume I of this report describes the methodology used to obtain the failure rates, presents the results of the analyses, discusses potential uses for the data, and provides recommendations for further research. Volume II provides a table of part failure rates and a list of records for the UH-60 see Appendix A and for the UH-1 see Appendix B.
