Aircraft Certification and PMA Manufacturing


Partnering with Amphenol CIT means more than getting a better way to create your product; it also means close support through the complex Certification and STC processes your launch may face. We’re experts with years of experience and a deep library of certificates that can help simplify and accelerate your product development.

Airworthiness Certification Services

When your path to market includes airworthiness certification with the FAA, EASA, or any of the dozens of regional authorities worldwide, count on us to provide the expertise and support to accelerate your certification process.

We are an FAA STC design approval holder with a staff of:

  • Certification experts
  • In-House Federal Aviation Administration Designated Engineering Representatives (FAA DERs)
  • Designated Airworthiness Representatives (FAA DARs)
  • Designated Manufacturing Inspection Representatives (FAA DMIRs)

This team combines to deliver the regulatory expertise and relationships to bring your product to market effectively and sustainably.

Amphenol CIT components fly on more than 90% of the commercial aircraft in service today. We have been awarded hundreds of STCs across a broad spectrum of systems and equipment and have been recognized by airworthiness authorities worldwide.

What is the Supplemental Type Certificate (STC) process?

For new STC applications, via the FAA Aircraft Certification Office (ACO), our team will:

  • Establish the required certification basis
  • Create associated project-specific certification plans
  • Apply for the STCs
  • Develop testing data and requisite reports for timely approval of your product for prototype installation
  • Review the engineering packages, including any customer-provided technical data required as part of the STC application
  • Issue statements of compliance in the data submitted to the FAA, EASA, and regional authorities

Our team will then support the prototype installation on the aircraft, including the required test activities, and generate:

  • The needed installation conformity documentation
  • Ground and/or flight test reports
  • Final submission of all documentation to the regulator

PMA/EPA Production

Our Franklin, WI facility has quality systems audited by the FAA and EASA specifically for the production of retrofit aircraft parts.

We can also manufacture PMA- and EPA-approved parts under contract with the issuance of a PMA assistance letter from an STC holder. This allows us to apply to the local FAA MISO for PMA against the specific component(s) and support high-volume manufacturing and fleet-wide retrofit programs efficiently.
