FAR 91.883 — Stage 3 Noise Authorizations
FAR 91.883 explains when non-Stage 3 jets weighing 75,000 lbs or less may operate in the contiguous U.S. under a special flight authorization.
FAR 91.883 restricts operations of jet airplanes weighing 75,000 pounds or less that do not meet Stage 3 noise levels. After December 31, 2015, these airplanes generally cannot fly in the contiguous 48 states unless the operator obtains a special flight authorization from the FAA.
A special flight authorization may only be issued for one of these purposes:
- Selling, leasing, or using the airplane outside the 48 contiguous states
- Scrapping the airplane
- Modifying it to meet Stage 3, 4, or 5 noise levels
- Performing scheduled heavy maintenance or significant modifications at a U.S. facility
- Delivering the airplane to a lessee or returning it to a lessor
- Preparing, parking, or storing the airplane for any of the above activities
- Providing emergency relief transport of persons or goods
- Diverting to an alternate U.S. airport for weather, mechanical, fuel, ATC, or other safety reasons during one of the above flights
Applications go to the FAA's Office of Environment and Energy and must be filed at least 30 days before the flight (except for emergency relief flights). This rule matters because it limits where and why older, louder jets can operate, helping reduce community noise exposure.
