A Comparative Evaluation of Two Types of Aviation Maintenance Documents: Maintenance Instruction Manuals and the 'Work Packages'.
Abstract
The MIMs (Maintenance Instruction Manuals) for the APQ-126 Radar Set were rewritten in a style and format that requires less experience, skills, reading comprehension, and analytical abilities to effectively perform the maintenance on this system. All subjects were tested individually for approximately two hours with the main interview divided into five sections. Four of the sections consisted of instructions, demonstrated problems, maintenance problems to be solved by the subject using both MIMs and WPs, and questions or comments on which set of documents were easier to use and why, e.g., differences in ease of finding the required information, ease of using tables and figures, ease of reading instructions, use of schematics, wiring diagrams, component parts location, etc. A fifth section of the interview consisted of an overall summary evaluation of both sets of documents. A description is given for each of the five sections of the interview which include External Access Tasks, Internal Access Tasks, Pictorial and Symbolic Reference Tasks (use of IPBs), Procedural Directions and Decision Making Tasks, and Overall Summary Evaluation. After each section the subject answered questions or commented on his evaluation of the two sets of manuals as being easier to locate the required information, to use in working the problems, to use when working in a shop, differences in how the two sets of manuals were written, and any other comments about the two sets of manuals or the evaluation questions.
