Abstract

The workcard is the primary document that controls an aircraft inspection task and serves as a major factor influencing inspection performance. The present study develops a methodology for design of workcards, based on the application of human factors knowledge to the analysis of aircraft inspection tasks. A taxonomy for design of usable documentation was developed using four basic categories: information readability, information context, information organization, and physical handling/environmental factors. Within the framework of this taxonomy two extreme representative conditions of aircraft inspection tasks, the A-check and the C-check, were analysed for usability. Issues for workcard redesign were identified within the taxonomy using data from user responses. These were then used to develop alternative design solutions offering improved usability. The increase in usability was measured using inspections of DC-9 aircraft, and proved significant. Not only does this study propose specific design solutions, it also provides a generic methodology that can be followed for design of quality documentation for other aircraft inspection tasks. This methodology is currently being extended for the design of usable information for automated workcards and hypermedia-based documentation.
