If you notice a fault or malfunction during a shift, what should you do?

• A. Ignore it until end of shift.
• B. Repair it yourself.
• C. Report it to the supervisor and log the issue; secure vehicle if necessary.
• D. Notify ATC only.

Answer: (C)

When you notice a fault or malfunction, safety-first handling means reporting it to your supervisor and logging the issue, and securing the vehicle if there’s any risk. This gets the problem into the maintenance process and prevents the vehicle from being used until it’s checked and repaired. Do not try to fix it yourself unless you’re specifically trained and authorized to perform that maintenance. Notifying ATC alone isn’t enough because they don’t handle vehicle maintenance or fault records, though they may need to know if the fault affects operations.
