2026 GA Parts Survey: Supply Chain Pressures on Aging Fleet
TBX survey finds 66% of GA maintenance pros expect parts availability to worsen as the piston fleet averages 53 years old.

General aviation maintenance professionals are spending more time hunting for parts and technical data than managing costs, as supply chain friction threatens the operational viability of an aging piston aircraft fleet.
In a press release issued on August 23, 2026, TBX, operating as Airworthy.com, published the findings of its 2026 General Aviation Parts Survey. The accompanying summary report, titled “The Great Parts Squeeze,” details the mounting pressures on maintenance shops tasked with servicing a certified general aviation (GA) piston fleet that now averages 53 years of age.
Supply chain friction and industry sentiment
The survey data indicates widespread pessimism regarding the near-term outlook for component availability. According to the report, 66% of surveyed industry professionals expect the aviation parts supply environment to worsen in the near future. Dissatisfaction is prevalent across multiple metrics, with 72% of respondents reporting frustration with parts pricing and 59% expressing dissatisfaction with current lead times.
Despite the high concern over pricing, the report highlights that the sheer time required to source components and access Illustrated Parts Catalogs (IPCs) has become the primary operational bottleneck for maintenance providers.
“Maintenance shops are spending too much time searching for parts, finding part numbers, waiting on backorders, and sourcing alternatives,” said Jon McLaughlin, CEO of TBX.
McLaughlin added that this administrative burden includes the time spent explaining limited options, or the complete lack thereof, to customers waiting for their aircraft to return to service.
Strategies for an aging piston fleet
With the average certified GA piston aircraft now over half a century old, the industry faces compounding challenges in keeping legacy airframes airworthy. The TBX report suggests that maintaining this fleet will require broader acceptance and availability of alternative components, including Parts Manufacturer Approval (PMA) items and serviceable used parts, alongside traditional Original Equipment Manufacturer (OEMs) supplies.
“As the GA fleet continues to age, improving parts availability, expanding access to technical data, and giving maintainers more options will be critical to keeping these aircraft flying,” McLaughlin stated in the release.
The company intends for the survey data to serve as a baseline for manufacturers and suppliers to address these bottlenecks. McLaughlin noted that the friction points identified by maintenance professionals require a coordinated response, stating that the issue cannot be solved by any single segment of the industry alone.
AirPro News analysis
The findings in the TBX report quantify a reality we hear frequently from general aviation maintenance providers. As the legacy piston fleet ages past the 50-year mark, the original supply-chains that supported these aircraft have often consolidated, pivoted to turbine markets, or ceased operations entirely. The high dissatisfaction with lead times points to a structural gap in the market. While PMA manufacturers have stepped in to produce high-demand replacement parts, the long tail of low-volume, specialized components remains a significant vulnerability for GA operators. If supply chain friction continues to outpace solutions, we may see an increase in aircraft grounded not for lack of funds, but for lack of basic hardware and approved technical data.
