Factors to Consider When Choosing Aircraft Parts Suppliers

​Aviation is known for its stringent, highly standardized processes. To meet the standards, aircraft operators must be equally thorough in choosing suppliers. Picking the right supplier isn't just about operational success. It's critical to aviation safety.

Aircraft parts come in two forms: Original Equipment Manufacturer (OEM) and aftermarket parts. OEM parts are the same standardized parts as those the aircraft came with. The aircraft companies or their designated suppliers produce them. Third-party companies manufacture aftermarket parts based on the original design. A new aircraft comes with genuine components and parts. The challenge is in sourcing the spare parts. 

Aircraft parts dealers can be OEMs, distributors, brokers, or MROs (Maintenance, Repair, and Overhauls). Some distributors only sell the parts. Others operate as MROs, selling parts and offering repairs and maintenance services. Aircraft parts sources are OEMs, third-party manufacturers, salvage yards, or online marketplaces, e.g., eBay and Amazon.

The kind of supplier one chooses will dictate how intricate the evaluation process is. OEMs are considered trustworthy. Every aircraft spare part, regardless of its source, must pass the Federal Aviation Administration's (FAA's) stringent tests. That's how genuine distributors get the FAA's parts manufacturer approval (PMA), allowing them to sell third-party parts.

Another factor to look for in a supplier is its supply chain efficiency. In the aviation industry, downtime can be costly. Consequently, a supplier's ability to avail the parts promptly is a critical factor. Timeliness isn't the only factor either. An efficient supply chain is also about accuracy. Signs of logistical capabilities include inventory depth, MRO expertise, and a solid track record of reliability.

OEM parts offer a sense of certainty regarding compatibility and adherence to regulatory standards. However, they come with a hefty price tag. While quality is crucial for durability and safety, cost matters, as it's a key trade-off to consider when choosing a supplier. One should pick a supplier that offers an acceptable cost/quality trade-off. For example, a used part in a sound condition may be more cost-effective than a new one.

All genuine aircraft spare parts should be traceable to the manufacturer. Due to increases in the manufacture and distribution of fake aircraft parts, traceability of parts helps limit the likelihood of using counterfeit parts. Traceability records capture a part's entire history - the manufacturer, all the users, and maintenance and repairs done. An OEM stockist should have a certificate of conformance to prove that the parts are OEM.

Most aircraft operators prefer to work with MROs. It's efficient and cost-effective. The alternative is to source parts from one distributor and then hire another company to install them. Even for aircraft operators who can handle maintenance and repairs in-house, it's safer to choose a supplier with repairs and maintenance expertise, like Alaris Aerospace Systems. Such a supplier can be invaluable in helping one choose the correct parts.

Things to consider when choosing an MRO are their location, availability, and scope of service. The last thing one wants is to have to switch between providers mid-project. Signs of capabilities include the latest testing software and handling tools. Service providers that offer a warranty for their parts and repair services are preferable.

The criteria for picking a supplier go beyond where they source the parts, price, and expertise. One should also consider customer service and the opportunities for enduring relationships. A warranty is a telltale sign a supplier isn't only interested in making a quick sale. It demonstrates a supplier's confidence in their parts and expertise.
