FAA Certification Paths for Airplane Parts

Three FAA approval types govern production of certified airplane parts. Each type carries distinct legal authority and installation eligibility.

A Parts Manufacturer Approval (PMA) is a combined design and production approval issued under 14 CFR Part 21 Subpart K. It authorizes a manufacturer to produce and sell replacement or modification parts for installation on specific type-certificated aircraft. PMA eligibility ties to particular applications, not model-agnostic use. PMA data is searchable at drs.faa.gov, which supports independent verification.

A Production Certificate (PC) is issued under 14 CFR Part 21 Subpart F. It authorizes a manufacturer to produce duplicate products, including aircraft, engines or propellers, under an approved type design without individual FAA conformity inspections on each unit. OEM parts produced under a PC provide full traceability to the original type design.

A Technical Standard Order Authorization (TSOA) is issued under 14 CFR Part 21 Subpart O. It functions as both a design approval and a production approval confirming an article meets the applicable TSO minimum performance standard. TSOA is model-agnostic and approves an article against a performance class standard. Installation eligibility still requires a separate approval such as an STC or inclusion in the type design.

Procurement teams complete several verification steps before issuing any purchase order.

  1. Search the FAA Dynamic Regulatory System at drs.faa.gov to confirm active PMA or TSOA status.
  2. Verify AS9100 certification independently through the IAQG OASIS database and avoid reliance on a certificate supplied by the vendor.
  3. Confirm ITAR registration status for any defense or space-related components.
  4. Require a Certificate of Conformity, material certifications and applicable test reports with every shipment.
  5. Confirm the supplier traceability system links purchase orders, material lot records, work travelers, inspection records and shipment documentation.

Precision Advanced Manufacturing operates under AS9100D, ISO 9001:2015 and ITAR-compliant quality systems with full traceability across materials and processes. Start the supplier qualification process with a quote request.

Supplier Tiers in the U.S. Airplane Parts Market

The U.S. certified-parts ecosystem divides into three primary tiers: OEMs, PMA holders and contract manufacturers.

OEMs such as Boeing, GE Aerospace and Raytheon Technologies produce parts under Production Certificates tied to their own type designs. They represent the highest-cost sourcing path but provide direct compatibility with original type designs.

PMA holders are independent manufacturers authorized to produce replacement or modification parts for specific type-certificated aircraft. Chromalloy, headquartered in Palm Beach Gardens, Florida, holds FAA approval on gas-path PMA parts. Jet Parts Engineering, based in Seattle, Washington, received FAA approval in May 2026 for new PMA parts covering engine inserts, impellers and preformed packings across multiple commercial platforms.

Contract manufacturers occupy a critical mid-tier role. They produce precision components to customer-supplied designs under certified quality management systems, including AS9100D, ISO 9001 and ITAR, without holding their own type certificates. This tier serves OEMs, PMA holders, defense primes and Tier 1 integrators that require scalable, compliant machining and fabrication capacity without building it in-house.

The U.S. aerospace and defense electronics manufacturing services market reached approximately $25 billion in 2023, which reflects the scale of this mid-tier contract manufacturing segment.

How Major OEMs Source Airplane Parts

Boeing and other major OEMs source components across a multi-tier supply chain that spans OEM-owned facilities, Tier 1 integrators and mid-tier contract manufacturers. Procurement decisions at every tier follow a consistent framework built around four priorities.

Traceability. AS9100 requires traceability down to part, lot, batch and serial number level, plus configuration control confirming the correct drawing and specification revision was used. Mid-tier contract manufacturers operating under AS9100D provide this linkage across purchase orders, material certifications, work travelers, inspection records and shipment documentation.

Every critical dimension is verified — CMM inspection and AS9100D-controlled quality workflows produce first-article and in-process data you can trace to each part.

Scalability. Programs require suppliers that can move from prototype validation to full-rate production without a supplier change. First Article Inspection per AS9102 Rev C must be completed and documented before serial production begins. This requirement establishes objective evidence that design characteristics, materials and functional requirements are verified.

Compliance. Major OEMs including Boeing, Lockheed Martin and RTX require IAQG OASIS verification of active AS9100 certification as a baseline condition for approved supplier list inclusion. ITAR registration functions as a non-negotiable requirement for defense and space programs.

Integration support. Suppliers that deliver fully finished, ready-to-integrate components eliminate secondary work and reduce assembly cycle time. Mid-tier manufacturers with in-house finishing, hardware installation and kitting capabilities reduce handoffs and improve production control.

Deloitte’s 2026 Aerospace and Defense Industry Outlook notes that contractors are increasingly exploring additive manufacturing and digital production tools to augment constrained casting and forging supply chains and enable more localized production of selected components. This trend reinforces the strategic value of domestic mid-tier manufacturers.

Frequently Asked Questions

What is the difference between a PMA and a TSOA for airplane parts?

A Parts Manufacturer Approval authorizes a manufacturer to produce specific replacement or modification parts for identified type-certificated aircraft. Eligibility ties to particular aircraft applications. A Technical Standard Order Authorization approves an article against a minimum performance standard for its class, such as an avionics unit or life vest, and is model-agnostic. A TSOA does not by itself authorize installation on an aircraft, so a separate approval such as an STC or inclusion in the type design is required. PMA is the more common approval path for structural and mechanical replacement parts, while TSOA is standard for avionics, instruments and appliances.

How can a procurement team verify a supplier’s FAA certification status?

PMA and TSOA status can be searched directly through the FAA Dynamic Regulatory System at drs.faa.gov. AS9100 certification must be verified independently through the IAQG OASIS database, not solely from a certificate the supplier provides, to confirm the registration is active, issued by an accredited certification body and covers the scope of work being purchased. ITAR registration is maintained by the U.S. Department of State Directorate of Defense Trade Controls. Procurement teams complete all three verifications before issuing a purchase order or adding a supplier to an approved supplier list.

What traceability documentation should a certified aerospace parts supplier provide?

A complete traceability package for certified aerospace parts includes a Certificate of Conformity, material certifications tying specific heat or lot numbers to the shipment, applicable test reports, work order or traveler records, tooling and calibration evidence, nonconformance records and final acceptance documentation. AS9100 Rev D requires both forward traceability from material receipt to shipment and backward traceability from a shipped unit back to source materials, process history and acceptance records. Procurement teams specify these requirements explicitly in purchase orders and supplier quality agreements as a condition of acceptance.

Can a mid-tier contract manufacturer support both prototype and full-rate production for certified aerospace programs?

Mid-tier contract manufacturers operating under AS9100D and ITAR-compliant quality systems are structured to support the full program lifecycle. The key requirement is that the same quality processes, documentation standards and traceability systems validated during First Article Inspection carry forward into serial production without interruption. Precision Advanced Manufacturing’s scalable production platform, which supports prototype through multi-shift manufacturing, is designed to enable this transition without a supplier change and protect program timelines while reducing qualification risk.
