Given the time, money and effort being invested to satisfy Crew Resource Management (CRM) training requirements, there is surprisingly little empirical data to guide CRM course content. In military programs, CRM training is often organized around a set of elements that are listed in service-wide training regulations, with roughly equivalent attention being paid to each area. If some CRM processes are more closely related to mission outcomes than others, the value received from CRM training might be increased through greater focus on areas of greatest need. Military and commercial aviation research findings and recommendations led the Air Force to require a more data-driven approach to establish specific behaviorally anchored CRM training objectives. The Air Mobility Command, the C-130 Aircrew Training System Program Office, Lockheed Martin, and The Air Force Research Laboratory formed a partnership that is now conducting a series of studies and analyses to identify and prioritize CRM training requirements for C-130 aircrews. This paper discusses two analyses of existing data: (1) instructor observations recorded in student training folders during mission qualification training, and (2) mishap report narratives and associated databases of causal and contributing human factors that are maintained by the Air Force Safety Center. In both cases, the original data were generated for other purposes, but were made available for these CRM analyses. Each proved to be a fertile source of insight regarding specific CRM behaviors that need to be considered in redesigning CRM instruction. We describe these two data sets, our analytical approach, trends identified, and implications for CRM training. We anticipate that these analyses will contribute to the development of observable CRM training objectives that will, in turn, enable compelling transfer of training assessments of resulting changes in CRM training.
