FAR 91.881 — Subsonic Jet Noise Compliance
FAR 91.881 requires civil subsonic jets under 75,000 lbs to meet Stage 3, 4, or 5 noise levels when operating in the contiguous U.S. after Dec. 31, 2015.
FAR 91.881 sets the final noise compliance deadline for smaller civil subsonic jet airplanes — those weighing less than 75,000 pounds — that fall under § 91.801(e).
Key points:
- After December 31, 2015, you may not operate one of these jets to or from any airport in the contiguous United States unless it has been shown to comply with Stage 3, Stage 4, or Stage 5 noise levels.
- The only exception is the limited relief available under § 91.883 (special flight authorizations).
- Older, louder Stage 1 and Stage 2 jets in this weight class are effectively grounded from the lower 48 states.
Why it matters operationally: If you fly or dispatch business jets, you must verify the airplane's noise stage in the type certificate data or aircraft records before operating into the contiguous U.S. A non-compliant aircraft can't legally depart or arrive without a § 91.883 waiver, regardless of the airport or time of day.
