Aircraft Disinsection at Portsmouth International Airport at Pease (PSM)
Pease is New England’s classic staging point before a crossing: one of the longest runways in the region, on-field customs, and handling used to transatlantic business aviation. An aircraft staging through PSM for a disinsection destination can be treated here, at the last US port before the flight.
If your next departure from PSM 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. Expect us at Portsmouth within 24 to 36 hours of confirmation; booked departures are guaranteed for the date.
About Portsmouth International Airport at Pease
Portsmouth at Pease is built for the crossing: a very long former Air Force runway, on-field customs and handlers who see transatlantic business aviation daily. For an aircraft staging through PSM before a flight to a disinsection destination, the treatment happens here, at the last US port, before boarding.
Where the requirement comes from
The requirement belongs to the country you are flying to, and it is met at the last port before that country. Leave Portsmouth non-stop and PSM is that port, so pre-embarkation treatment of the empty aircraft here, before boarding, satisfies the destinations that accept the method. Add a stop and the picture changes; tell us the routing and we will place the treatment correctly.
Departures from PSM that trigger a disinsection requirement are mostly transatlantic. Italy is the one that catches operators most often, because it applies to aircraft arriving from the United States; Greece joined the list in September 2025, and Greece, Morocco, Egypt, India follow. A non-stop crossing from Portsmouth International Airport at Pease makes PSM the last port before the destination, which is exactly where pre-embarkation treatment belongs.
How it works on the PSM ramp
We coordinate with your FBO and crew, arrive ahead of the agreed time, and treat the aircraft where it is parked once catering and cleaning are complete and the cabin is empty. Cabin, flight deck and holds are treated to the WHO method, the aircraft is ventilated and released for boarding after the required wait, and the certificate goes aboard with the flight documents. Passengers arrive to a treated aircraft.
