PMA Parts You Should Stock Up On for Cost Savings and Reliable Operations

Maintaining a single aircraft or an entire fleet can require significant financial investment from stakeholders, especially when it comes to sourcing reliable replacement parts. However, proactive inventory management can reduce long-term costs while improving operational reliability across a wide variety of aviation operations, with options like PMA parts posing even further benefits. This blog will explore how stocking specific PMA components can offer cost-saving opportunities and contribute to more efficient maintenance processes, so read on to learn more.

What Are Parts Manufacturer Approval (PMA) Parts?

PMA parts are components approved by the Federal Aviation Administration (FAA) for use on type-certificated products like aircraft engines, and propellers, generally being produced by someone other than the original equipment manufacturer (OEM). This approval is granted through a structured process involving comprehensive testing and quality assurance measures to verify compliance with required safety and performance standards.

What Are the Advantages of Using PMA Parts in Aviation?

PMA parts are often cost effective when compared to their OEM counterparts, leading to increased adoption among many commercial airlines and MRO providers. These parts are also beneficial for their ability to reduce acquisition expenses while also mitigating risks tied to sole-source OEM supply chains.

What Are Categories of PMA Parts Worth Stocking?

To maximize value and preparedness in the face of a volatile market and unexpected issues, operators should emphasize stocking parts across the following categories:

Airframe Components: These parts include products like panels, brackets, and structural reinforcements that undergo frequent stress and benefit from proven non-OEM replacements.
Engine Accessories: Items like seals, gaskets, and filters are typically replaced at regular intervals, with PMA options often offering substantial cost savings.
Electrical and Avionic Parts: Components like connectors, wires, and relay modules are commonly available as certified PMA options.
Interior Hardware: Commonly replaced items like fasteners, seat components, panel fittings, and other items are highly recommended to stock up on with their varying availability.
Hydraulic System Components: PMA parts like actuators, valves, and fittings are all suitable for a wide variety of demanding high-performance systems.

How to Identify Reliable PMA Suppliers and Distributors

When evaluating PMA part providers, it can be beneficial to assess the following key factors to ensure both consistent quality and adherence to regulatory compliance:

Certifications and Accreditations: It is always beneficial to select a distributor that operates with AS9120B, ISO 9001:2015, and FAA AC 00-56B accreditation, as well as other certifications that signal adherence to stringent quality management protocols.
Traceability and Documentation: Each component offered should be accompanied by relevant documentation to verify airworthiness and traceability.
Industry Reputation: Working with a distributor known for reliability can improve the likelihood of receiving high-caliber parts and attentive customer support.
Availability and Lead Times: Reliable suppliers can fulfill high-demand or urgent orders in a timely manner, which may help reduce maintenance delays.
Support Services: Many reputable suppliers can support customers with technical resources and expertise to aid in product validation and installation processes.

What Are the Best Practices for Managing PMA Part Inventory?

To achieve greater cost efficiency and reduce exposure to supply chain disruptions, aircraft operators should implement the following best practices for managing their PMA part inventory:

Usage Forecasting: Regular analysis of maintenance data can help forecast part consumption patterns and guide more strategic stock replenishment decisions.
Rotable Pooling: Maintaining a shared pool of high-value, reusable PMA components can enable quicker turnaround times while minimizing capital investment in spare parts.
Shelf-Life Monitoring: For components sensitive to time and environmental conditions, monitoring shelf life and ensuring proper storage parameters can help preserve airworthiness.
Digital Tracking Tools: The use of digital inventory systems can support automated reordering and improve alignment with planned maintenance activities.
