What are the primary responsibilities of the Crew/Operator during PMCS?

• A. Perform PMCS, Enter Faults on the 5988E/2404, Update 5988E as needed.
• B. Schedule PMCS only
• C. Inspect for fuel leaks and nothing else
• D. Fill out training forms

Answer: (A)

During PMCS, the Crew/Operator acts as the first-line maintainer. The essential task is to perform the preventive checks and services and, if faults are found, record them on the official forms (the 5988E or 2404) and keep the 5988E updated as needed. This documentation links the operator’s observations to maintenance action, helping ensure the equipment is safe to operate and that its readiness status is accurate. Scheduling PMCS or focusing on a single issue like a fuel-leak check doesn’t capture the full responsibility, and filling out training forms isn’t part of the PMCS process.
