What document provides a detailed account of maintenance activities performed?

• A. Maintenance Log
• B. Maintenance Service Report
• C. Work Order
• D. Inspection Sheet

Answer: (B)

This question focuses on how maintenance documentation records what actually happened during service. A Maintenance Service Report is the record that details the actions taken during maintenance, including specific tasks performed, parts replaced, quantities, labor hours, who did the work, dates, test results, and any notes about equipment condition or follow-up recommendations. This level of detail makes it the right choice for a “detailed account of maintenance activities performed.”

Think of it this way: a Maintenance Log is a running history of events and may show that maintenance occurred, but it doesn’t necessarily capture the full narrative of what was done in each session. A Work Order is the instruction or plan for maintenance—what needs to be done, often including materials and labor estimates—not the post-work record of actions taken. An Inspection Sheet records findings from an inspection and the condition observed at that moment, not the completed maintenance work and its specifics.
