Participation in Joint Oil Analysis Program (JOAP) or Spectrometric Oil Analysis (HU-25) is what for certain components and optional for others?

Explanation:
Oil analysis is a proactive diagnostic tool that checks for wear metals and contaminants in used lubricant to gauge the condition of components. For some critical parts—where a failure would be unsafe or highly costly—the policy makes oil analysis participation mandatory to ensure regular trending and early warning of abnormal wear. This allows maintenance to be scheduled before a problem escalates. For other components that are less critical or have lower risk/impact from wear, participation is optional. So, involvement in JOAP or HU-25 oil analysis is required for certain components and optional for others.
