Line maintenance refers to routine, limited maintenance tasks performed on an aircraft before, between, or after flights to keep it serviceable for daily operations and to clear minor defects without returning the aircraft to a hangar. In maintenance manuals, work orders, MRO documentation, and dispatch-related forms, it is distinguished from hangar or heavy maintenance and typically includes inspections, fluid and tire servicing, and component replacement within approved limits.

Check source meaning → confirm the preferred term → record approved variants and references.
This term appears in maintenance programs, turnaround inspection checklists, dispatch documentation, and MRO service agreements. Translators encounter it when localizing job cards, logbook entries, and reliability reports, where line maintenance must not be rendered as line-fabrication or electrical line work. It also occurs in software for ramp operations and scheduling.
The most serious error is translating “line maintenance” as “线路维护,” which suggests electrical wiring or circuit maintenance rather than ramp maintenance between flights. This can misdirect maintenance staff and misclassify tasks, especially in job cards and logbook descriptions where task type affects dispatch decisions. Less severe but also common is treating it as heavy maintenance.

Review status: questions to confirm
Use the source’s named category and surrounding document context. Preserve any supplied classification or unresolved scope question for the technical owner.
Check nearby aircraft, ramp, task-card and logbook context so “line maintenance” is not rendered as maintenance of electrical lines or wiring.
Retain supplied station names, card and logbook identifiers, revision labels and links between entries; do not infer task eligibility or release status.
Share a representative maintenance record excerpt with its source language, revision and supplied category references.
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.
Include the source and target languages, file types, intended use, deadline and any approved termbase. Agree handling before sending sensitive files. Acknowledged in 4 hours, quoted in 24.
