Plain English Meaning

All the checking, fixing, and looking-after work done on an aircraft to make sure it stays safe to fly and meets the rules.

Full Definition

The inspection, servicing, repair, overhaul, and preservation work performed on an aircraft to keep it in a safe, airworthy condition that meets regulatory standards.

Context Anchor

Seen in aircraft records, required inspections, preflight planning, flight school operations, and conversations with mechanics or instructors.

Derivation

‘Maintenance’ comes from the Old French maintenir, meaning ‘to hold in hand’ or ‘keep up.’ In it carries that same sense — keeping the aircraft held to the required for flight, not letting it below airworthy condition.
