Although the term MRM was used for several years following CRM's introduction, the first governmental guidance for standardized MRM training and its team-based safety approach, appeared when the FAA (U.S.) issued Advisory Circular 120-72, Maintenance Resource Management Training [1] in September, 2000.
Like CRM, MRM training emphasizes a team approach to human error reduction using principles that seek to improve communications, situational awareness, problem solving, decision making, and teamwork.
[2] Some variation of human factors training, whether called MRM or not, is now standard at many commercial airlines, aircraft manufacturers, and aviation-related organizations.
Drawing on data from the Federal Aviation Administration, National Aeronautics and Space Administration, National Transportation Safety Board, and commercial airline sources, the Coast Guard finally implemented a U.S. Navy-developed variant of MRM.
These "latent errors" included such mistakes as failure to follow published aircraft manuals, lack of assertive communication among maintenance technicians, poor supervision, and improper assembly practices.
