Choosing PMAs From HRD
Are you looking for quality, compliant aircraft replacement components? If so, choose PMA parts from HRD Aero Systems. You can access over 400 PMA sub-assembly components to service your aircraft’s oxygen systems, fire extinguishers and survival products.
What Are PMA Parts?
PMA parts are aircraft parts that HRD and other companies produce under a Parts Manufacturer Approval from the Federal Aviation Administration (FAA). They undergo rigorous quality control and testing and are reliable alternatives to original equipment manufacturer (OEM) components. Some airlines accept these products to promote a competitive parts market.
A PMA is a design and production approval that allows HRD to:
- Produce and sell specific aircraft replacement parts for installation on type-certificated aircraft.
- Market the parts as FAA-approved.
- Compete in the aftermarket by offering an OEM alternative.
- Certify that the parts conform to the approved design and are safe for installation on the specified aircraft.
FAA oversight ensures PMA parts meet stringent quality and performance standards, giving you peace of mind that they are reliable and efficient. The design approval stage certifies that the components meet airworthiness directives.
Applicants demonstrate compliance through tests and computations — each PMA could take months or years to develop. The certification, prototyping and development costs may surpass $100,000 for every approved part.
The Different Types of PMA Components
HRD offers different PMA replacement parts, including:
- Oxygen cylinders: These products meet pressure ratings, material specifications and testing requirements, making them safe to install on a specified aircraft.
- Discharge valves: Compatible with specific cylinder and mask connections, HRD builds discharge valves with the appropriate pressure regulation and flow rate for the oxygen system.
- Cartridges/Squibs/Pin Pullers: These energetics trigger the release of 1301 halon for engine, APU, and cargo bottles and are critical to operation. Additionally, they are used in some inflatable systems such as off-wing slides and helicopter floats.
- Discs and Fill Fittings: A mandatory replacement on all 1301 halon fire bottles, these cannot be reused, therefore, are replaced at every overhaul.
- Pressure gauges: Featuring a durable construction resistant to temperature and vibration changes, PMA pressure gauges offer accurate and reliable oxygen cylinder pressure readings.
- Gaskets: PMA gaskets can withstand temperature and pressure within the oxygen system, fire bottle, or inflatable and offer a tight seal to prevent leaks.
Why Choose PMA Parts?
PMA parts are FAA-certified OEM replacements. Their form, function and fit are the same as those of the original component. PMA manufacturers may also introduce innovative design improvements to enhance part performance and durability, making such PMA components better than OEM options.
In addition to delivering reliable quality, PMAs also offer benefits such as:
- Cost savings: PMA parts are often more affordable than OEM parts.
- Old aircraft model support: If the manufacturer has discontinued replacement components, you can rely on PMA parts to maintain older aircraft.
- Short lead times: PMA manufacturers offer shorter lead times, reducing an aircraft’s maintenance turnaround time.
- Diverse options: You can get more product choices for your maintenance program.
