Federal Aviation Administration (FAA) Certification Overview

NAT has a Memorandum of Agreement (MOA) with the FAA (Seattle Aircraft Certification Office (SACO) and Seattle Manufacturing Inspection District Office (MIDO)), which establishes the processes and timelines for NAT to obtain Supplemental Type Certificates (STC) for major changes (modifications or alterations). This authority was implemented due to the number of FAA STC projects NAT had initiated with the ACO and MIDO combined with the overall expertise and experience of our in-house certification staff. NAT’s certification staff includes two (2) Management/Administrative DERs, a Cabin Safety DER, four (4) Electrical Systems & Equipment DERs (including software) and DER authority for Structures, Mechanical Systems and Flammability. NAT also holds the following FAA approvals: • FAA Parts Manufacturer Approval (PMA) • FAA Organizational Designated Airworthiness Representative (ODAR) • FAA Repair Station (Number NX0R661Y)

European Aviation Safety Agency (EASA) Certification Overview

NAT holds an EASA Design Organisation Approval (DOA) (Certificate Number EASA.21J.347) which entitles NAT to perform design activities under applicable European regulations within the scope and terms of our approval. More specifically, our DOA has been granted for designing major changes to interiors, avionics, structures, and mechanical systems. Our DOA privileges allow NAT to: • Perform design activities under Part 21 • Obtain EASA STCs • Classify changes to type design as “major” or “minor” • Approve minor changes to type design.

To view NAT’s DOA approval on the EASA website refer to: http://www.easa.eu.int/doc/Certification/Org_Appro/easa_doa.pdf

NAT is currently in the process of obtaining an EASA Production Organization Approval (POA) (EASA Project Number P-EASA-21G-0017). The issuance of the POA will enable our parts kits (where the type design is approved under our DOA) to ship with EASA Form 1 (authorized release certificate).
