If an engine overhaul is mandatory for flight operations conducted by a company, who can extend the overhaul time?

• A. FAA
• B. Manufacturer
• C. FAA-approved repair station
• D. Certificated inspector

Answer: (A)

Extending a mandatory overhaul time is a change to regulatory maintenance intervals, and that authority rests with the aviation regulator. The manufacturer may define recommended or required intervals, but any legal extension must be approved by the FAA to ensure continued airworthiness. The FAA can authorize an extension through approved data changes, field approvals, or amendments to the maintenance program. An FAA-approved repair station must follow approved data and cannot unilaterally extend the interval, and a certificated inspector certifies compliance with existing rules rather than granting extensions. So, the FAA is the entity that can authorize extending the overhaul time.
