Envoy Aerospace - Services

As a matter of fact, the partners of Envoy Aerospace combine for over seventy years of experience. We have participated in more than 1000 STC projects. From flight deck designs to wheels and brakes, and small singles to the largest Boeing or Airbus airliners, we have the experience. You need an innovative solution? We can help. Many of the projects we work are “first-of-type” approvals. Certain first-of-type approvals require new policy from the FAA to ensure the highest safety standards are being maintained. Often, we help shape that policy.

We have made it our goal to surround ourselves with the brightest, hardest working and most innovative thinking persons in the aviation industry.

When it comes to aviation certification,
we know what it takes and we have done it.
