FAA PMA Parts

Get your quality, dependable Parts Manufacturer Approval (PMA) aviation replacement parts from HRD Aero Systems’ wide selection. These components meet the same specifications as the Original Equipment Manufacturer (OEM) and comply with the stringent quality mandates of the aviation industry set forth by the Federal Aviation Administration (FAA)

What Are FAA PMA Aircraft Parts?

PMA parts are aircraft replacement components that comply with the Federal Aviation Administration’s PMA regulations for airworthiness. PMA aircraft parts are functionally equivalent to OEM parts to serve as a compatible alternative that delivers on performance and quality.

Since the OEM doesn’t make these parts, PMA parts undergo a rigorous approval process to ensure they meet or exceed OEM standards. The FAA defines the approval standards for the design and production of replacement parts. With FAA approval, part manufacturers are permitted to develop and sell PMA parts for installation on various aircraft components.

How PMA Replacement Parts for Aviation Are Approved and Certified

Part manufacturers design aircraft components that meet or exceed the safety, performance and quality standards of the OEM part. Then, the company submits evidence to the FAA to prove that the component meets the regulations and that manufacturing processes will maintain this quality in future production runs.

The FAA prescribes the approval procedures, so they will use these standards to evaluate the component and the provided evidence. Once approved, manufacturers can distribute the parts to airlines and aircraft maintenance providers.

Traceability, Documentation and Airworthiness Compliance

Numerous regulations and orders define the PMA process for manufacturers, engineers and inspectors, including:

  • 14 CFR Part 21, Subpart K, for how to obtain PMA certification

  • 14 CFR Part 43 for maintenance and rebuilding standards for replacing OEM parts with PMA components

  • 14 CFR Part 45, Subpart B, for marking and identifying parts to make them traceable and prove authenticity

The FAA maintains the Dynamic Regulatory System — listings of FAA PMA parts with information such as the part name and number, PMA holder name, and the make and model on which the part can be installed. All components that have aircraft PMA approval are added to this database.

PMA vs. OEM Parts: Performance, Safety and Cost

When maintenance, repair and overhaul services are required on aircraft, you must choose between PMA and OEM parts. Both offer the same fit and function, as they are virtually identical in performance and meet the same safety standards.

PMA aircraft parts generally cost less than OEM parts, which is a significant benefit for airlines and aircraft maintenance providers seeking to manage their repair costs. In addition, the aviation industry needs parts and components to be available in a timely manner. PMA manufacturers have more flexibility in supply chain management than OEM providers, making parts readily available.

The primary benefit OEM parts have over PMA parts is widespread acceptance. The aviation industry has misconceptions about PMA parts, believing that these have lower quality and performance. Some aircraft financiers restrict aircraft operators from using PMA parts. In these cases, OEM parts are the best option for making necessary repairs.
