Which of the following includes all the regulatory definitions of 'maintenance'?

• A. overhaul, repair, parts replacement, inspection, and preservation
• B. Cleaning and lubrication
• C. Only overhaul
• D. Parts replacement and inspection only

Answer: (A)

Maintenance, as defined by the regulations, covers the actions needed to determine an item is safe to operate and to restore it to that safe condition. This definition includes five elements: overhaul, repair, replacement of parts, inspection, and preservation. Cleaning and lubrication are common servicing tasks, but they aren’t listed as part of the formal regulatory definition of maintenance. That’s why the best choice is the one that includes all five elements—overhaul, repair, parts replacement, inspection, and preservation—because it matches the complete regulatory scope. The other options miss at least one of these required elements (for example, including only overhaul, or only parts replacement and inspection, or focusing on cleaning and lubrication), so they don’t fully align with the official definition.
