Connecticut Aircraft Noise Federally Preempted Statewide

Federal law occupies the field of aircraft noise and operations. The Airport Noise and Capacity Act of 1990 (49 USC 47521 et seq.) and FAA regulations preempt state and municipal attempts to regulate aircraft in flight, takeoff, or landing noise. The Second Circuit confirmed this preemption in Tweed-New Haven Airport Authority v. Tong, striking a Connecticut statute restricting runway expansion. Connecticut municipalities therefore cannot enforce noise ordinances against overflights or airport operations. Airport proprietors may impose limited Stage 3 access restrictions only after FAA review under 14 CFR Part 161. Ground-based airport activities outside aircraft operations remain subject to general state and local noise rules.

Local ordinances purporting to regulate aircraft noise are unenforceable and subject to federal preemption challenge; airports violating ANCA risk loss of federal airport funding under 49 USC 47524.
