Global Certification Solutions
Unit Members

Envoy Aerospace is a group of dedicated professionals committed to providing an unsurpassed level of service when it comes to aircraft type certification solutions. Envoy Aerospace specializes in helping clients obtain U.S. (FAA) Supplemental Type Certificates (STC) for major design changes on aircraft.

As the aviation community becomes more and more globally oriented we provide assistance to our clients as they look to include foreign aircraft type approval to their modification programs.

Envoy is pleased to offer our services as an FAA STC Organization Designation Authorization (ODA). This delegation offers some additional autonomy over conventional certification methods. The goal of the ODA is to make certification timelines more predictable. Being a relatively new program between industry and the FAA results in a conservative position while the FAA becomes comfortable with these new organizations and their procedures. As a result, there has not been a dramatic change in the processing times of STC’s. The most noteworthy improvement is access to the ODA in a manner consistent with the industry – seven days a week, twenty-four hours a day. As we pass our second anniversary as an STC ODA, we are seeing efficiency improvements and we work with the FAA on a regular basis to ensure continuous improvement in our performance.

ODA does not fit all projects. There are many types of modifications that require conventional certification processes. Envoy continues to maintain our Partnership for Safety Program (PSP) with the FAA. The PSP allows us to work these conventional projects using management DER’s and the many individual designees still authorized by the FAA. Under PSP, we are able to provide service that parallels the ODA certification timelines very closely.

The Envoy leadership is passionate about aviation and we have assembled a great team of employees and contractors, all of whom are dedicated to providing top-shelf service.
