How does root cause analysis drive corrective actions in CBM T6?

• A. Focuses on symptoms only.
• B. Identifies underlying cause to implement targeted actions that prevent recurrence, not just symptoms.
• C. RCAs are optional.
• D. Only modifies procedures without analysis.

Answer: (B)

Root cause analysis in CBM T6 is about tracing failures to their underlying cause so corrective actions address the real fault and stop recurrence. When a symptom appears, RCA digs into contributing factors across equipment, processes, and people, using condition data to uncover why the degradation began. Once the root cause is identified, targeted actions are applied—such as adjusting maintenance intervals, revising lubrication or inspection procedures, replacing faulty components, or providing operator training—to remove the underlying driver of the problem rather than just masking the outward signs. The aim is to prevent repeat events by changing the underlying conditions that led to the failure, and follow‑up monitoring confirms that the improvement is sustained.

Fixing symptoms alone can lead to repeated failures because the root issue remains unresolved. RCAs are not optional; analysis guides the changes, ensuring that interventions address what actually caused the problem rather than just treating the visible effect. Modifying procedures without analysis misses the deeper cause and is unlikely to prevent recurrence.
