Thornton Aviation Backs Sea Aviation Transplant Fleet

MRO Thornton Aviation provides around-the-clock AOG response that has kept Sea Aviation’s organ-transplant fleet airborne through situations where a grounded aircraft could mean a missed transplant window.

The Part 145 repair station at Van Nuys Airport (KVNY) in Southern California provides maintenance for Sea Aviation’s Hawker 800XP fleet. These midsize twinjets are used to transport organs, physicians, and medical teams for transplant missions across the U.S.

Sea Aviation currently operates two Hawker 800XPs dedicated to transplant logistics, with a third coming soon and a long-term goal of expanding to as many as 10. With this mission type, aircraft availability is a direct variable in patient outcomes.

“Everything is time critical,” said Sea Aviation aircraft asset manager Michael Harkins. “You see all this play out step-by-step. The aircraft fires up, they get where they need to go, and hopefully you save a life in the process.”

Thornton Aviation handles routine and unscheduled maintenance, inspections, AOG response, and avionics and connectivity upgrades. Harkins said the value of the relationship is defined by responsiveness and the ability to solve problems under pressure, including outside normal business hours.

In one instance, an organ was already in transit when an aircraft needed immediate attention. Harkins began reaching out at 2 a.m., and Thornton Aviation director of maintenance Hector Jimenez responded and resolved the issue. “Ten minutes after he completed it, the plane launched,” Harkins said. “It was that critical. We were that close to missing a flight.”

In a separate situation, a technician found a screw in one of the aircraft’s tires during an inspection. When a replacement wheel assembly arrived with the wrong part, the MRO sourced a temporary replacement, installed it for one mission, and then swapped it out with the correct assembly when it arrived. “That little thing—to use your resources like they do—is priceless,” he pointed out.

Thornton Aviation operates at Burbank and Van Nuys airports and holds FAA approval for more than 61 aircraft types.
