FAR 91.317 — Provisional Aircraft Limitations
FAR 91.317 sets operating limitations for provisionally certificated civil aircraft, covering eligibility, allowed uses, passengers, procedures, and maintenance.
FAR 91.317 governs how a provisionally certificated civil aircraft may be operated. These aircraft hold a temporary airworthiness certificate while still in the certification process, so the FAA tightly restricts their use.
Key points:
- The operator must be eligible for a provisional airworthiness certificate under §21.213.
- Operations outside the U.S. require specific approval from the Administrator and each foreign country.
- Operations in air transportation require approval from the Executive Director, Flight Standards Service.
- Allowed uses are limited to: type/supplemental type certification work, flight crew training (including simulated air carrier ops), manufacturer demonstration flights to prospective buyers, market surveys, flight checking of non-critical instruments/equipment, and service testing.
- The pilot must follow the prescribed limitations in the aircraft or flight manual; certification flights fall under §21.191 experimental limits, and flight testing under §91.305.
- Operators must establish approved procedures, ensure crew are qualified and familiar with the aircraft, and maintain it per applicable rules.
- Only persons with a proper interest (or specifically authorized) may be carried, and each must be told the aircraft is provisionally certificated.
This matters because provisional aircraft are not fully proven — operational discipline keeps the public and crew safe during the certification phase.
