Aircraft Disinsection in Pasco, WA: 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 ask for 36 to 48 hours of notice at PSC, 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.
On the field at PSC
PSC lies 2 miles northwest of Pasco, Washington, 410 feet above sea level. Its longest runway, 03L/21R, measures 7,707 by 150 feet, asphalt. PSC is towered and holds a Part 139 airport operating certificate. FBOs serving PSC include Bergstrom Aircraft; we treat the aircraft at whichever ramp or hangar it is parked on. We time the treatment to your PSC departure so the aircraft is ventilated and ready before boarding.
Where the aircraft disinsection 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, Fiji and the 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. Australia, New Zealand, Chile, French Polynesia appear on the list as well.
The aircraft disinsection process 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.
