Phoenix Sky Harbor and Mesa Gateway operate FAA Part 150 noise compatibility programs that restrict aircraft engine runups by time and location. Maricopa County has no separate airport-noise authority. Complaints route through airport noise offices and FAA.
Federal law (49 USC 47501-47533, FAR Part 150) governs airport noise; cities and counties cannot directly restrict aircraft operations. Phoenix Sky Harbor (PHX) limits maintenance engine runups to designated pads with curfews 10 PM-6 AM under its Part 150 program. Phoenix-Mesa Gateway, Deer Valley, Scottsdale, and Falcon Field have similar runup restrictions. Sky Harbor's Aviation Noise Office logs complaints at noise.skyharbor.com. Phoenix Code Chapter 4 sets surrounding overlay zoning to limit incompatible land uses. The Quiet Communities Act of 1978 preempts local rules on aircraft in flight. Helicopter noise from Sky Harbor's medical pads and police operations falls under FAA Order 8400.10. Maricopa County has no airport noise enforcement role.
FAA may fine airports or operators violating Part 150 programs up to $37,377 per violation under 49 USC 46301. Phoenix imposes contractual penalties on tenants violating runup pad rules. Local nuisance suits against airports are largely preempted under federal law.
