Abstract:The present paper seeks to describe and validate the effectiveness of five change programs (generically termed Maintenance Resource Management, or "MRM"). The activities evaluated here are in the middle stages of an ongoing MRM training program, or they are in their initial stages of program planning and bench marking. All programs are in U.S. air transportation companies and have been developed for maintenance personnel. The overall goal of these MRM training programs is to establish a long-term commitment to improving safe, dependable and efficient performance through effective communication at all levels in the airline maintenance operations. This report describes one year's evaluation of the effects of four air transport companies' MRM change programs. This evaluation focuses primarily on the attitudes and reported behaviors of Aviation Maintenance Technicians (AMTs) and the safety performance of their units. The results reveal a strong positive effect of the initial training, as well as some signs that additional intervention is required in order to sustain the results. Preliminary results from another company, just planning their MRM training are considered in light of the AMTs' results as well other programs studied earlier. 1997 report of research conducted under FAA Grant #96-G-003, to FAA Office of Aviation Medicine.
