Full Breakdown

The Federal Aviation Act preempts state and local regulation of aircraft operations and noise in flight. WAC 173-60-050(4)(b) explicitly exempts sounds originating from aircraft in flight and sounds related directly to such operations. Airport ground operations may be regulated locally. RCW 14.08 governs municipal airport authority but does not authorize noise rules conflicting with FAA Part 150 procedures.

Violations & Penalties

State and local enforcement is unavailable for in-flight aircraft noise; complaints route to the FAA or airport operator.

Frequently Asked Questions

Can a Washington city ban late-night flights?

Generally no. Curfews and operating restrictions require an FAA Part 161 study and approval. Municipalities cannot unilaterally restrict aircraft operations.

Does the state regulate airport ground noise?

Ground equipment such as auxiliary power units may fall under WAC 173-60 limits as stationary sources. In-flight aircraft sounds remain federally preempted.
