Aircraft Disinsection at Charles M. Schulz Sonoma County Airport (STS)
Charles M. Schulz Sonoma County Airport is wine country’s front door, where charter jets and owner-flown aircraft carry visitors in and out of Santa Rosa year round. If a departure from STS leads onto an itinerary that requires disinsection, we come to the aircraft here and complete the treatment and certificate before boarding.
If your next departure from STS is to a country that requires disinsection, we come to your aircraft here, treat it empty before boarding to the WHO pre-embarkation method, and issue the certificate for the flight. We typically reach STS within 24 to 36 hours of confirmation, and scheduled bookings are guaranteed for the departure.
About Charles M. Schulz Sonoma County Airport
Charles M. Schulz Sonoma County Airport mixes airline regional jets with a strong charter and owner ramp serving the wine country. Harvest season and event weekends fill its FBO with visiting business aircraft, and the itineraries that follow often continue to destinations with disinsection requirements on the books.
Where the requirement comes from
The rule is set by the arriving country, not by the airport you leave from. If your destination requires disinsection, the aircraft must be treated at the last port before that country, and for a non-stop departure from Santa Rosa that port is STS. Pre-embarkation treatment of the empty aircraft here is a method those countries accept.
From STS the requirement is mostly a Pacific one: Australia and New Zealand require disinsection on every arriving international aircraft, and the Cook Islands and Solomon Islands require it too. Many itineraries from Santa Rosa stop in Hawaii, which then becomes the last US port and the place for pre-embarkation treatment; non-stop departures are treated here at STS. New Zealand, Cook Islands, Chile appear on the list as well.
How it works on the STS ramp
At Charles M. Schulz Sonoma County Airport the treatment fits into the normal departure sequence. Catering and cleaning finish, the cabin is confirmed empty, and our technician applies the WHO pre-embarkation treatment through cabin, flight deck and holds. The aircraft rests, ventilates for the required wait, and is released for boarding with the certificate aboard and the treatment details in the crew’s hands for the General Declaration.
