JET-X is a microcomputer-based expert systems application for ground-based troubleshooting of the TF34-100 engines on the USAF A-10 aircraft. It provides fault isolation capabilities to supplement the current engine fault detection system. JET-X incorporates domain-specific knowledge from existing troubleshooting manuals, augmented and enhanced by a team consisting of a factory engineer with a background in engine performance analysis and a field technical representation with considerable on-site troubleshooting experience. The expert system shell used for this application is GEN-X. The authors describe the diagnostics scope and design objectives of JET-X as well as the development issues and the procedures used to produce this tool. Particular emphasis is placed on human-factors issues.
