Definition

Noun: A maintenance procedure, specifically an overhaul, performed on equipment or machinery during the period between its scheduled, regular overhauls. It is a partial or complete disassembly, inspection, repair, and reassembly conducted to address wear, prevent failure, or restore function before the next major scheduled maintenance event.
