FAA proposes $170,000 fine against Sonoma County Airport: what travelers should know
The Federal Aviation Administration has proposed a $170,000 civil penalty against Charles M. Schulz–Sonoma County Airport (STS) in California. The agency announced the enforcement action on November 12, 2026, citing alleged violations involving aircraft rescue and firefighting coverage and a required wildlife inspection.
The proposal is an allegation in an administrative enforcement process, not a final finding. The airport has 30 days after receiving the FAA notice to respond.
What the FAA alleges
According to the FAA, the airport did not provide the personnel and vehicles required for aircraft rescue and firefighting coverage for two passenger flights in March 2025. The agency says the coverage requirements were part of the airport’s FAA-approved Airport Certification Manual.
The FAA also alleges that the airport did not notify the airline that the required coverage was unavailable. For one of those flights, the agency says STS failed to perform a runway inspection for deer and other wildlife before the first flight of the day, as required by its approved wildlife-hazard management plan.
Does the proposal affect current flights?
The FAA announcement does not state that Sonoma County Airport is currently closed, that scheduled flights have been suspended or that passengers should avoid the airport. It describes an enforcement case concerning alleged conduct in March 2025.
Travelers should therefore avoid treating the proposed penalty as a current operational alert. A civil-penalty proposal and a live airport restriction are different things. Flight schedules can still change for weather, aircraft availability, crew issues or air-traffic restrictions, so passengers should check their airline’s app or website before leaving for the airport.
What passengers can check before traveling
Confirm the flight number, departure time and terminal directly with the operating airline.
Check the airport’s official service information for parking, ground transportation and terminal notices.
For same-day air-traffic disruptions, use the FAA’s official airport-status service rather than relying on social-media summaries.
If an airline changes or cancels a flight, review the carrier’s rebooking and refund options for that specific itinerary.
Charles M. Schulz–Sonoma County Airport uses the code STS and serves California’s North Bay and Wine Country. The FAA’s notice concerns the airport operator’s regulatory obligations; it does not establish that a particular passenger was injured or that either referenced flight experienced an accident.
