AirPro News analysis
We view the Doncasters IPO as a clear indicator of the sustained investor appetite for aerospace supply-chain assets. As original equipment manufacturers (OEMs) push to increase production rates, lower-tier suppliers are securing the capital necessary to expand capacity and meet the backlog.
The decision by a legacy British manufacturer to list on the NYSE rather than in London underscores the gravitational pull of US capital markets for aerospace and defense firms. US markets currently offer higher valuations and deeper liquidity pools for industrial companies positioned to benefit from global rearmament and the commercial-aircraft replacement cycle.

The strategic placement of the facility in Batam leverages existing industrial infrastructure and proximity to regional trade routes to attract maintenance contracts from across Southeast Asia-Pacific.
Lion Group President Director Captain Daniel Putut Kuncoro Adi emphasized the dual focus of the new enterprise.
“We hope this facility can serve domestic needs as well as friendly countries and further strengthen Indonesia’s aviation industry,” Adi stated, according to reporting by Aviation Business News.
Indonesian regulators also view the facility as a step toward greater self-sufficiency in the aviation sector. Sokhib Al Rokhman, Director of Airworthiness and Aircraft Operations at Indonesia’s Directorate General of Civil Aviation (DGCA), highlighted the broader national strategy during the launch.
“We want to strengthen aviation independence by making Batam Aero Engine an MRO hub that is efficient, responsive, and competitive in the Asian market,” Rokhman said, as reported by ePlaneAI.
AirPro News analysis
The establishment of Batam Aero Engine represents a calculated vertical integration Strategy by Lion Group. By bringing engine and APU maintenance in-house, the operator can better control maintenance costs and mitigate Supply-Chain bottlenecks that have constrained the global MRO sector in recent years. Furthermore, positioning the facility in Batam allows Indonesia to compete directly with established MRO hubs in neighboring Singapore and Malaysia. If the facility can secure third-party contracts as intended, it will mark a significant maturation of Indonesia’s domestic aviation technical capabilities and workforce.

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.
