Equipment Failure Root-Cause Investigation

Use this form to capture what happened, what you did to keep the operation running, the timeline, a structured root-cause analysis (5 Whys), and durable corrective actions so the same breakdown doesn't repeat. Saved submissions become a record for follow-up, parts ordering, and preventive maintenance planning.
