FAA Certification and Engineering Capabilities

Aeronautix specializes in the design, installation, and FAA certification of aeronautical products, focusing on 14 CFR Part 23 general aviation, Part 25 commercial aviation, and Part 21 parts manufacturer approval (PMA) projects. We’ve developed an extensive network of FAA DER and FAA DAR relationships, allowing for quick, cost-effective approvals from each required DER discipline in support of TC, STC, and PMA certification projects.
Aeronautix, along with our FAA DER and FAA DAR network, have decades of experience in the following core areas:

  • Aircraft Structures
  • Avionics
  • Electrical Systems and Equipment
  • Engineering Design & Construction
  • Flight Test
  • Ground Test
  • HIRF and Lightning
  • Mechanical Systems
  • Powerplant
  • Program Management
  • System Safety

Over these core areas, Aeronautix is skilled in the coordination, production, and execution of certification plans, analyses, compliance reports, substantiation reports, test plans, test reports, and detailed design, assembly, and installation drawing packages required for FAA approval of any STC or PMA application. Aeronautix supports every aspect of its certification programs including onsite DAR part and installation conformities as well as onsite DER witness testing to ensure the job is done and done right.

Aeronautix also specializes in the design, analysis, and prototyping of components and systems. We utilize 2D and 3D CAD/CAM packages to optimize design, as well as various 3D printing and rapid prototyping technologies to ensure designs meet their intended purpose. In addition, Aeronautix employs modern FEA, CFD and classical techniques for structural, thermal, and flow analyses.

What is a TC (Type Certificate)?

A Type Certificate (TC) is an FAA design approval for a product or major design change to a product, and is issued to signify that the design or “type” meets the airworthiness requirements of 14 CFR. A product is defined as an aircraft, aircraft engine, or aircraft propeller. Each product has its own type certificate held and managed by the design approval holder (manufacturer).

Once a product has been issued a type certificate, it must remain in conformance with that type certificate and be operated within its approved limitations. If a type certificate holder wishes to change a product’s type design, the holder must apply for an Amended Type Certificate (ATC) or a Supplemental Type Certificate (STC).

All type certificate data sheets (TCDS) are public information and can be accessed through the FAA website. 

What is an STC (Supplemental Type Certificate)?

A Supplemental Type Certificate (STC) is a Type Certificate (TC) that is an FAA approval of a major design change to a previously type certificated product. An STC is issued to an applicant by the Aircraft Certification Office (ACO) once the design change has been shown to meet all applicable airworthiness requirements affected by the design change. 

There are two types of STC: a “one-only” STC and a “multiple” STC. A “one-only” STC is for the modification of one specific serial numbered aircraft, aircraft engine, or propeller, and this type of STC cannot be amended. A “multiple” STC is used to modify two or more aircraft, aircraft engines, or propellers. 

See “What is a TC?” above for more information on Type Certificates. 

All supplemental type certificates are public information and can be accessed through the FAA website.

What is a Field Approval?

A Field Approval, as defined by the FAA, is one of the means used by the FAA to approve technical data used to accomplish a major repair or major alteration. It is an approval by the Administrator, through an authorized Aviation Safety Inspector (airworthiness), of technical data and/or installations used to accomplish a major repair or major alteration. Technical data so approved becomes “technical data approved by the Administrator.” This type of approval may be accomplished for one-time approval. 

What is PMA (Parts Manufacturer Approval)?

Parts Manufacturer Approval (PMA), as defined by the FAA, is a combined design and production approval for modification and replacement articles. It allows a manufacturer to produce and sell these articles for installation on type certificated products. 

PMA is issued by the FAA once the applicant has shown compliance with the applicable requirements of 14 CFR Part 21 and has demonstrated a quality system that ensures each product and article conforms to its approved design and is in a condition for safe operation. 

What is TSO (Technical Standards Orders)?

Technical Standards Orders (TSO), as defined by the FAA, is a minimum performance standard for specified materials, parts, and appliances used on civil aircraft. When authorized to manufacture a material, part, or appliances to a TSO standard, this is referred to as TSO authorization. Receiving a TSO authorization is both design and production approval.

Receiving a TSO authorization is not an approval to install and use the article in the aircraft. It means the article meets the specific TSO and the applicant is authorized to manufacture it. An STC or field approval will usually be required to physical install the article onto the aircraft.

Program Management

Program Management

FAA DER - Program Management

A Management DER is a person who has been granted special authorizations that were introduced by FAA policy. While an FAA Management DER must hold a technical FAA DER delegation, their expertise goes beyond a specific technical FAA DER discipline. An FAA Management DER has proven themselves to be highly knowledgeable of the entire FAA aircraft certification process from FAA project application to FAA type certificate issuance.

The Aeronautix team has a proven track record of effectively managing all aspects of any program. Whether it’s aircraft engineering development or FAA certification, we provide an outstanding product:
