Marsh Aviation

Marsh Aviation is an aircraft engineering, design, maintenance and re-manufacturing company, situated on East Falcon Drive, at Falcon Field in Mesa, Arizona. The company often works as a sub-contractor to well-known brand-name aerospace companies, discreetly designing and manufacturing components and sub-systems for high-profile programs. The company has also worked on a variety of aircraft programs for governments all over the world.

Later, the firm also re-engined Gulfstream Turbo Cats, Beech Turbo Mentors and Grumman S-2 Trackers with Garrett engines.

The company filed for Chapter 11 bankruptcy in September 2009.
