Which program is used to monitor wear metals in lubrication fluids to assess engine wear?

• A. Joint Oil Analysis Program (JOAP)
• B. Lubricant Analysis and Wear Program (LAW)
• C. Oil Wear Monitoring Program (OWMP)
• D. Lubrication Condition Analysis (LCA)

Answer: (A)

Detecting engine wear by looking at metals in the lubrication oil comes from a dedicated oil analysis program that pairs regular sampling with metal analysis and trend review. The Joint Oil Analysis Program is built for this purpose in aircraft fleets: it standardizes how oil is sampled from engines and accessories, analyzes wear metals and contaminants, and interprets the data over time to identify abnormal wear early. By tracking changes in metal concentrations and comparing them to baseline and historical trends, technicians can decide on maintenance actions—such as inspections or parts replacement—before a failure occurs. Other programs may focus on lubricant cleanliness or degradation, but they don’t provide the same structured measurement of wear metals to assess engine wear.
