About the Instrument Breakdown Maintenance Report

A breakdown report turns a failure into knowledge. Recording the symptom, the real root cause and the time taken lets you spot repeat offenders, justify better instruments and add the right tasks to preventive maintenance. The cause category makes it easy to analyse trends across many reports.

How to fill in this template

  1. Enter the tag, start time and who reported the fault as soon as the complaint is received.
  2. Record each action as it happens with the time, person and hours.
  3. When the instrument is back in service, enter the restored time; downtime is calculated.
  4. Write the root cause, not just the symptom, and choose a cause category for later analysis.
  5. Record spares used and add a recommendation to prevent repeat failures.

What the formulas do

  • Downtime (hours) = (restored − breakdown start) × 24.
  • Total man hours = SUM of action hours.

Frequently Asked Questions

What should an instrument breakdown report include?

Tag, time of failure and restoration, symptom, root cause, actions with man hours, spares used and a recommendation to prevent recurrence.

Why separate symptom and root cause?

The symptom is what the operator saw; the root cause is why it happened. Only fixing the root cause stops repeat failures.

How is downtime calculated?

Restored time minus breakdown start, in hours.
