Records compiled during the _____ maintenance of apparatus, facilities, or pieces of equipment can predict a trend or justify a replacement.

• A. corrective
• B. resolution
• C. interpretation
• D. preventative

Answer: (D)

Maintaining thorough records during preventative maintenance lets you track how equipment performs and wears over time. By logging inspections, lubrication, parts replaced, and test results, you build a trend view of condition and reliability. When data show progressive wear, rising failure rates, or declining performance, you can forecast remaining useful life and justify replacing equipment before a failure occurs. This proactive use of maintenance records supports planning and asset management.

Records from corrective maintenance tell what failed after the fact and what was done to fix it, which isn’t as useful for forecasting or justifying replacement ahead of time. The other terms don’t represent the same proactive, trend-based use of records for replacement decisions.
