Fault Isolation Manual故障隔离手册
A fault isolation manual is a technical document that provides step-by-step procedures to trace a reported fault to its source, using observed symptoms, built-in test results, and system schematics. It appears in troubleshooting documentation and line maintenance workflows to guide technicians toward the most likely failed component or connection, often through fault codes, line-replaceable unit replacement steps, and wiring checks.

Where this term appears
This term appears in aircraft troubleshooting manuals, on-board maintenance system menus, and line maintenance task cards. Translators encounter it when localizing fault code tables, maintenance messages, and go/no-go decision steps where precise wording for tests, rechecks, and component replacement is necessary for safe dispatch, especially under minimum equipment list and time-limited dispatch constraints.
Translation checks
A frequent error is translating fault isolation as “troubleshooting” in very broad terms, losing the manual’s structured sequence from symptom to fault code to component. Another mistake is translating “most likely” language too strongly, implying a specific component is definitely failed when the source text allows for probability and further verification.
Keep the term aligned across your files
Check procedure sequence, part names, limits and cautions against the supplied references. Applicable aviation or market requirements depend on the product and project pathway.
Provide approved terms and previous translations with the source files. Agree how variants, ambiguous wording and revisions will be reviewed. Terminology maintenance and any termbase handback are confirmed in the project scope. See the 8-step AI + expert workflow.
