Supply Chain Challenges in General Aviation

Airworthy.com recently unveiled its 2026 General Aviation Parts Survey, shedding light on the ongoing supply chain difficulties facing general aviation maintenance shops. With a considerable 66% of surveyed professionals predicting worsening conditions, the data underscores a pressing need for improvements in parts availability and access to technical resources.

The Context of the Survey

Conducted by TBX's CEO Jon McLaughlin, this research tapped the insights of a broad spectrum of aviation maintenance professionals, including mechanics, shop owners, and Directors of Maintenance. The aim was to identify the barriers they encounter while sourcing, purchasing, and managing aircraft parts. Not surprisingly, the findings pointed out that time is the predominant challenge in these operations rather than cost.

Major Findings from the Survey

The data collected highlighted several key issues confronting the industry:

• - Parts Supply Anxiety: A significant 66% of maintenance professionals anticipate that the situation regarding parts supplies will deteriorate further in the coming years.
• - Dissatisfaction Indicators: Strikingly, 72% expressed dissatisfaction with parts pricing, while 59% noted frustrations with lead times for parts delivery.
• - Access to Information: An overwhelming majority identified access to Illustrated Parts Catalogs (IPCs), part numbers, and other technical data as the most impactful change that could enhance maintenance operations.

The Woes of Maintenance Shops

As elucidated by McLaughlin, maintenance shops are expending an excessive amount of time on tasks that should be more straightforward. The processes of searching for parts, deciphering part numbers, managing backorders, and evaluating alternatives consume valuable time, which could otherwise be directed toward servicing customers. In an industry where aircraft are aging—evident in the average certified GA piston aircraft being 53 years old—these inefficiencies could have dire implications for safe and reliable aviation.

Different Strategies by Shop Size

Interestingly, the strategy employed to mitigate these challenges varies significantly between smaller and larger operations. Smaller maintenance shops often use a broader mix of sources, such as OEM, PMA, and salvage parts, thereby increasing their flexibility. Conversely, larger, turbine-focused shops remain heavily reliant on OEM suppliers, which could lock them into longer wait times and limited options.

A Call for Action

Respondents to the survey pinpointed improved access to parts information as a clear and actionable opportunity for enhancing operational efficiency. Having straightforward access to illustrated parts catalogs and relevant technical data would allow maintenance professionals to navigate the complexities of aircraft servicing much more efficiently.

“This isn't a challenge that one segment of the aviation sector can tackle alone,” stated McLaughlin. “Yet, the frontline maintainers who interact with these aircraft daily know where the challenges lie. Our goal was to provide hard data to back up their experiences, giving manufacturers, suppliers, and the broader general aviation community tangible issues to address.”

Conclusion

The findings from the 2026 General Aviation Parts Survey, dubbed The Great Parts Squeeze, offer crucial insights into the current obstacles in general aviation parts access. The complete report features comprehensive results, charts, and analyses designed to equip the industry with actionable data for improving parts availability and overall maintenance efficiency. As the field continues to evolve, addressing these challenges will be essential in ensuring the longevity and safety of general aviation aircraft.
