Aircraft Disinsection at Tri Cities Airport (PSC)
Tri-Cities Airport in Pasco serves the Columbia Basin’s science, agriculture, and wine country. If your flight out of PSC is bound for a nation that mandates disinsection, the treatment happens right here before departure.
If your next departure from PSC 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 PSC within 24 to 36 hours of confirmation, and scheduled bookings are guaranteed for the departure.
About Tri Cities Airport
Hanford science, irrigated farmland, and a fast-growing wine industry shape the traffic at Tri-Cities Airport in Pasco. Engineering and research travel tied to the national laboratory keeps corporate aviation busier than the market’s size would suggest. Airlines reach the western hubs from a 7,707-ft primary runway, under some of the driest, most flyable skies in Washington.
Where the requirement comes from
Whatever the destination, the mechanism is the same: the arriving country requires the aircraft to have been disinsected, and pre-embarkation treatment at the last port before that country, performed on the empty aircraft, is a method it accepts. For a non-stop flight out of PSC, that last port is PSC.
From PSC 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 Pasco stop in Hawaii, which then becomes the last US port and the place for pre-embarkation treatment; non-stop departures are treated here at PSC. New Zealand, Cook Islands, Chile appear on the list as well.
How it works on the PSC ramp
On the day, the sequence at PSC is simple: our crew is at your hangar or FBO ahead of time, the cabin is confirmed empty and prepared, the treatment is applied to the WHO method through cabin, flight deck and holds, and the aircraft rests, ventilates and is released for boarding after the required wait. Your crew receives the certificate and the details to enter on the General Declaration before the door closes.

PSC disinsection questions, answered
Is PSC in your coverage?
It is. We treat aircraft at Tri Cities Airport on the ramp or in the hangar before boarding, and we handle our own travel to Pasco. Send us the destination and date and we will confirm the plan.
Does a flight from PSC to Australia need disinsection?
Yes, Australia requires it on arriving aircraft, and pre-embarkation treatment at PSC before boarding is a method it accepts for a non-stop flight. New Zealand, Cook Islands, Chile are other common cases from Pasco. Send us the route and we will confirm the plan.
When should we book disinsection for a trip out of PSC?
As soon as the trip from Pasco is likely. We hold the plan with you and adjust if the departure moves; if Australia or New Zealand is on the itinerary from PSC, start earlier still because of the operator paperwork.
Can one treatment at PSC cover an outbound and a return?
No. Pre-embarkation covers one flight sector, the flight it is performed for. The return to the US carries no US disinsection requirement; onward international legs need their own consideration. Send us the itinerary from Pasco and we will map it leg by leg.
