Federal Aviation Production Approval Holder - FAA PAH

What does it mean to be a Federal Aviation Authority Production Approval Holder (FAA PAH)?

An FAA PAH is a company or legal entity that holds any one of the following approvals issued by the FAA: a production certificate (PC), an approved production inspection system (APIS), a parts manufacturer approval (PMA) or a technical standard order (TSO) authorization. The approval holder controls the design and is responsible for product quality.


CertifyNation has earned an FAA Part Manufacturing Approval (PMA). Our in-house manufacturing facility was audited by the FAA and is a Production Approval Holder (PAH) with a Parts Manufacturing Approval (PMA), which includes the ability to issue authorized release documents and control preposition articles.

How is the Federal Aviation Authority Production Approval Holder (FAA PAH) designation achieved?

A company or legal entity must apply to their geographic FAA Manufacturing Inspection Satellite/District Office (MISO/MIDO) in accordance with the procedures and requirements contained in 14 CFR Part 21 Subpart F, G, K or O, and Advisory Circular 21-43.

Once the application is accepted, the MISO/MIDO will review the applicant’s quality management system (QMS) and then conduct an on-site audit or inspection of the applicant’s production facility. If the MISO/MIDO is satisfied with the QMS review and facility inspection, the MISO/MIDO will issue the production approval letter, in the case of CertifyNation a PMA letter.



How can CertifyNation’s FAA PAH benefit their customers?

All US-based commercial aircraft operators that want to retrofit their aircraft must do so with parts that have been certified as airworthy, defined by 14 CFR Part 21 requirements. These are parts that have FAA TSO, PMA or other certifications.  CertifyNation, as an FAA PAH, can produce FAA PMA parts and installation kits that are certified airworthy per these FAA requirements.

CertifyNation has earned a FAA Part Manufacturing Approval (PMA). Our in-house manufacturing facility was audited by the FAA and is a Production Approval Holder (PAH) with a Parts Manufacturing Approval (PMA), which includes the ability to issue authorized release documents and control preposition articles.

As a PMA holder, CertifyNation is approved to design, manufacture and sell FAA PMA parts, assemblies and customized kits for FAA aircraft modification and replacement projects. This approval ensures that the product’s materials and manufacturing processes follow FAA regulations and the product can be installed on an FAA-certified aircraft.

Our PMA facility allows customers to start and finish their aircraft modification and aircraft certification project efficiently with CertifyNation. After achieving an STC, CertifyNation’s in-house facility can immediately begin manufacturing parts and kits to streamline the installation process and minimize the amount of time aircraft are grounded.

Quality Management

What is AS9100?

AS9100 is the international Quality Management System standard for aviation and space and defense industry. AS9100 takes the ISO 9001 requirements and supplements them with additional quality system requirements, which are established by the aerospace industry to satisfy DOD, NASA and FAA quality requirements. The standard intends to establish a single quality management system for use within the aerospace industry.  “AS9100 Certified” means an organization has met the requirements of AS9100D.

CertifyNation has achieved AS9100 Revision D and ISO 9001:2015 certification under The Angelus Corporation’s newly consolidated quality management system (QMS), providing customers with confidence when trusting CertifyNation with Supplemental Type Certificate (STC) development or FAA PMA kitting needs. AS9100D is a supplement to ISO 9001:2015 that is specifically designed to meet rigorous aerospace industry requirements and enhance product safety and quality. These international quality management standards establish a framework for aerospace manufacturers to build robust quality systems that provide reliable products and services. The AS9100D certification illustrates The Angelus Corporation’s dedication to continuous improvement and providing high-quality products to its customers.CertifyNation AS9100 certification


What’s the difference between FAA PAH and AS9100D?

If a company is an FAA PAH, they are not automatically AS9100D certified and vice versa.  Only a company that holds an FAA PAH can produce parts certified as airworthy per 14 CFR Part 21 requirements. Currently, neither ISO9001 nor AS9100D is an FAA requirement, but the FAA recognizes the benefits of these systems. The implementation of AS9100D quality system elements and ISO 9001 certification are indicators of the applicant or PAH’s commitment to quality management/assurance principles. CertifyNation is both an FAA PAH and AS9100D certified.

Supplemental Type Certificate (STC)

What is a supplemental type certificate, and when is one required?

An STC (Supplemental Type Certification) is issued by a civil aviation authority, such as the Federal Aviation Administration (FAA) or European Aviation Safety Agency (EASA),  to an applicant who modifies or alters an aircraft, engine, propeller or appliance from its original type design. Civil aviation authorities usually require an STC for major changes to the design of a type-certified aircraft when the modification is not significant enough to require a new type certificate.

STC’s are issued for many changes including things like in-flight entertainment and connectivity, in-seat power,  or changes to the aircraft avionics. CertifyNation has decades of experience in the industry and has completed STC certifications of several different systems. See a listing of our STCs.

How does the STC process for the FAA work?

The FAA STC process for aircraft modifications is complex and CertifyNation is committed to simplifying and streamlining the lengthy process for customers. The infographic “8 Steps to STC Issuance” was designed to map the FAA STC process and clarify the requirements to earn an STC. The eight major steps to STC issuance include:

  1. Initial Technical Coordination Meeting (ITCM) and Aircraft Survey: Hold an Initial Technical Coordination Meeting (ITCM) to outline the technical and logistical details of the certification project. If necessary, conduct an aircraft survey to determine the compatibility of the new part and target airframe.
  2. File STC Application with FAA: File an FAA STC application using form 8110-12 to initiate the certification process.
  3. Design and Substantiation Data Development: Develop the required engineering drawings and substantiation data detailing how the part will be installed on the aircraft and how the installation is compliant with the applicable Federal Aviation Regulations (FARs).
  4. Receive TIA from FAA or ODA: Submit the engineering, certification and substantiation data to the FAA or Organization Designation Authorization (ODA). Once the FAA or ODA verifies the data complies with regulations and guidelines, a Type Inspection Authorization (TIA) is issued.
  5. Prototype Aircraft Installation: Once the TIA is issued, the prototype installation can begin.
  6. Inspection and Testing: Once the prototype installation is complete, the authorized FAA or ODA designee will inspect and conform the installation, and witness the applicable ground and flight testing to verify system performance and non-interference with other aircraft systems.
  7. Receive FAA STC: An STC is issued after successful completion of the prototype installation, installation inspection and ground/flight testing.
  8. Foreign STC Validation: An FAA STC can be validated by Civil Aviation Authorities around the world, including EASA (Europe), CAAC (China) and CASA (Australia).

8 Steps to STC Issuance

What are the biggest challenges to the STC process?

A few of the most common challenges to the STC process are access to an aircraft for prototype installation and testing, access to aircraft technical data, program scheduling challenges and managing the governing civil aviation authority.

How can an outside organization help mitigate some of those challenges? 

A certification partner, like CertifyNation, will have the engineering and regulatory expertise to review the aircraft’s existing avionics configuration. The review will determine whether the existing avionics can support ADS-B functionality and what ADS-B equipment is required to meet the mandate’s regulatory and performance requirements.

What should airlines and original equipment manufacturers look for when evaluating certification partners?

Airlines and OEMs should look for partners with significant experience working through the STC process combined with detailed knowledge of civil aviation authority regulations, and aircraft systems and structures.

Experienced partners with strong working relationships with civil aviation authorities and extensive engineering capabilities will be able to accelerate the certification timeline by reducing design iterations and eliminating parts or designs that are not compliant with applicable regulations. To further streamline the new part installation process, a partner with FAA parts manufacturer approval (14 CFR Part 21) will be able to manufacture parts, assemblies and customized kits. CertifyNation, as an FAA PAH, can produce FAA PMA parts and installation kits that are certified airworthy per these FAA requirements.
