The report describes the latest phase in the program to develop and evaluate PIMO Presentation of Information for Maintenance and Operation a job guide concept applied to maintenance. Between August 1968 and April 1969, a test was conducted at Charleston AFB, South Carolina, to determine the effectiveness of PIMO. Experienced and inexperienced Air Force technicians performed maintenance on C-141A aircraft using PIMO Job Guides presented in audiovisual and booklet modes. Performance was measured in terms of time to perform and procedural errors. The performance was compared with the performance on the same jobs by a control group, i.e., experienced technicians performing in the normal manner. The following conclusions were drawn from the test results 1 after initial learning trials, both experienced and inexperienced technicians using PIMO can perform error-free maintenance within the same time as experienced technicians performing in the normal manner, 2 inexperienced technicians perform as well as experienced technicians when both use PIMO, 3 there is no significant difference between audio-visual and booklet modes, 4 the users revealed an overwhelmingly positive reaction to PIMO, and 5 the performance improvements provide the capabilities to significantly improve system performance defined in terms of departure reliability, time-in-maintenance, and operational readiness.
