What defines the full overhaul level of maintenance?

The full overhaul level of maintenance is characterized by comprehensive procedures that address both the functional and structural integrity of a system or component. This level of maintenance typically involves disassembling equipment completely, performing extensive inspections, and replacing any worn or damaged parts. Additionally, it includes resetting operational thresholds to ensure that the equipment meets the original performance specifications.

The notion of "full maintenance with reset of thresholds" implies a meticulous and thorough approach, ensuring that all components are inspected, serviced, and calibrated properly. This intensive care helps to maximize the longevity and reliability of the equipment, making it fit for continued operation and safety standards.

In contrast, the other options refer to less exhaustive maintenance practices. Options that mention minimum service, partial inspections, or basic maintenance focus on more superficial checks and do not encompass the comprehensive scope and depth of an overhaul. Such practices may not involve disassembly, replacement of parts, or resetting thresholds, thereby falling short of what constitutes a full overhaul.
