Choosing aircraft parts is not for the faint-hearted. Every component plays a role that goes beyond fit and function. High-quality aircraft parts ensure safe flights and maximum efficiency.
Whether you own a personal aircraft or are part of an aircraft maintenance team, this guide will help. Here are six steps you need to follow to choose the right aircraft parts to reduce downtime and maintenance time:
-
Evaluate OEM vs. PMA
First things first, choose between OEM and PMA aircraft parts. As the name indicates, Original Equipment Manufacturer (OEM) parts are produced by the original manufacturer or the design holder. OEM parts, therefore, promise greater compatibility and brand trust.
Parts Manufacturer Approval (PMA) parts are produced by FAA-approved third-party manufacturers, often through reverse engineering. They offer similar quality at 30–40% lower costs and can sometimes have an improved design durability over the original.
So which is better? There’s no one-size-fits-all answer. OEM parts are recommended for critical systems, whereas PMA parts can be great for routine replacements.
-
Prioritize Quality and Certification
With both OEM and PMA parts, it’s important to prioritize quality and certification. First, make sure the part is FAA-approved for your specific aircraft. Then, check the Technical Standard Order (TSO) and Supplemental Type Certificate (STC).
A TSO confirms that the part needs general performance standards. However, it doesn’t automatically mean that part is approved for your specific aircraft number. This is where STCs come in. It authorizes specific modifications or alternative installations for a particular aircraft model.
-
Audit for Compatibility
An aircraft part could be 100% FAA-approved, but if it’s not compatible with your specific aircraft, it’s of no use to you. Therefore, always check your specific aircraft model before placing an order.
Need parts for a Cessna 152? Look for suppliers that offer a wide range of quality Cessna 152 parts. Cross-check your aircraft’s make, model, and serial number range.
-
Evaluate Supplier Reliability
Not all aircraft parts suppliers are the same. This is why it’s important to evaluate the industry reputation of different suppliers. Look for reviews from previous customers to evaluate the supplier’s product range, pricing, and transparency.
Remember that a reliable supplier doesn’t hesitate when you ask for certification or evidence for traceability. Pilot John International is one of the most trusted names in the industry.
-
Check Traceability
Before placing an order, make sure the aircraft parts are traceable. Authorities like the FAA and the EASA mandate meticulous tracking of components.
Buying aircraft parts with comprehensive documentation demonstrates adherence to these rules during audits and inspections. Save yourself from fines, penalties, or the grounding of aircraft.
-
Always Inspect Parts
Even with detailed documentation, aircraft parts can have defects. This is why an on-site inspection of parts is non-negotiable.
Check the packaging for signs of tampering, damage, or poor quality. Remember that genuine FAA-approved parts always arrive in labelled packaging and are sealed.
Conclusion
High-quality aircraft parts are difficult to source. But their benefits outweigh the effort. Moreover, if you follow the right steps, such as finding a reliable supplier and confirming documentation, the process will be straightforward.
