Built like a Skunk Works.
Proven like a prime.

Since 1987, Snow Aviation International has done what few independent firms can: take on whole-aircraft engineering — design, modification, and certification — and deliver it with the speed of a small team and the rigor of a major prime.

Our Story

Founded on the workshop floor.

SAI was built around a simple conviction: the people who understand an aircraft best are the ones who have designed it, bent its metal, flown it, and certified it. That hands-on, whole-aircraft knowledge is rare — and it's the company's foundation.

From the company's earliest C-130 cockpit-modernization work, SAI has operated like a Skunk Works: a tight group of highly experienced professionals, free to move fast, solving the hard engineering that larger organizations treat as too small, too specialized, or too slow to pursue. Across more than three decades, that approach has produced certified modifications, flight-test aircraft, and original designs.

Flown by those
who set the standard.

SAI's flight-test aircraft have been flown by the most demanding aviators in the world.

Pictured at the controls of SAI's C-130E test aircraft (N307SA) is Gen. Norton Schwartz, who went on to serve as the 19th Chief of Staff of the United States Air Force — a measure of the caliber of people who have trusted, evaluated, and flown SAI's work.

01

Whole-aircraft

We don't bolt on a fix. We understand the complete platform and engineer changes that work with it — nose to tail.

02

Certified, not theoretical

Anything we design is meant to fly and to be approved. Certification discipline is built into the work from day one.

03

Fast & focused

A small, senior team moves faster than a bureaucracy — delivering prime-level capability without the overhead.
