This article is based on an official press release from Aircraft Structures Group.

On March 31, 2026, Nashville-based Aircraft Structures Group (ASG) announced the completion of its 250th business jet repair. According to the company’s official press release, this milestone underscores the rapid growth of the FAA Part 145 certificated repair station since its founding in 2021.

We note that ASG has carved out a highly specialized niche within the aviation Maintenance, Repair, and Overhaul (MRO) sector. By focusing on mobile, rapid-response Aircraft on Ground (AOG) services, the company dispatches specialized teams directly to grounded aircraft worldwide, 24/7/365, bypassing the traditional need to ferry aircraft to fixed hangars.

The company, headquartered south of Nashville, Tennessee, specializes in aircraft fuel tank systems, fuel leak detection and repair, structural maintenance, corrosion and bacterial remediation. To meet surging demand, ASG noted in its release that it is actively recruiting new aircraft mechanics and expanding its visibility at industry events.

The Critical Role of Mobile AOG Services

In the business aviation sector, an “Aircraft on Ground” (AOG) designation indicates that a plane is mechanically unsafe to fly. For corporate jet operators, AOG situations trigger cascading logistical disruptions, dissatisfied clients, and severe revenue losses. Traditional repairs often require a special ferry permit to fly the aircraft to a maintenance facility, adding days or weeks to the timeline.

ASG’s mobile MRO model addresses this financial pain point by bringing technicians, tools, and parts directly to the tarmac. Every minute saved translates directly to cost savings for the operator, making rapid-response teams highly lucrative and essential to the modern aviation ecosystem.

Specialized Fuel Tank Maintenance

Fuel tank repair is widely considered one of the most difficult and hazardous tasks in aircraft maintenance. Technicians must enter confined integral fuel tanks that recently held explosive kerosene. This environment requires strict safety protocols, including defueling, venting dangerous vapors, testing for combustible gases, and wearing specialized respirators and non-static protective suits.

Precision is paramount in these environments. Leaks typically occur when sealant on tank seams loses its integrity. Technicians must meticulously remove old sealant without damaging the aluminum structure before applying new compounds. If not executed perfectly, the tank will re-leak once pressurized. To address this specific industry challenge, ASG operates on a “No Re-Leak Confidence” philosophy, backing all repairs with a comprehensive one-year warranty, leveraging a team with over 100 years of combined aviation maintenance experience.

“Reaching 250 business jet repairs is more than just a number, it represents 250 times that an operator trusted us with their aircraft, and 250 times our team delivered… Each repair reflects our founding promise: get aircraft back in the air safely, on time, and with the lasting quality our customers deserve,” stated ASG CEO Bertrand Carret-Troncy in the company’s press release.

Industry Tailwinds Driving MRO Demand

To understand the rapid scaling of ASG’s operations in less than five years, it is helpful to examine broader macroeconomic trends in business aviation. According to a February 2026 report by Mordor Intelligence, the global business jet MRO market is projected to experience steady growth, expanding from $30.12 billion in 2025 to $31.09 billion in 2026, and is expected to reach $36.39 billion by 2031.

A primary driver of this growth is the aging global fleet. Industry data indicates there are currently more than 8,000 business jets older than 15 years entering heavy-maintenance windows. As these aircraft age, fuel tank sealants naturally degrade, and airframes require more frequent structural inspections and corrosion treatments.

AirPro News analysis

We observe that the current Supply-Chain environment is creating a significant boom for specialized maintenance crews. Original Equipment Manufacturers (OEMs) are currently facing 18- to 24-month backlogs for new aircraft. Consequently, operators are forced to extend the life cycles of their current fleets rather than replacing them.

This dynamic shifts the industry’s focus from acquisition to preservation. Companies like ASG, which provide the gritty, highly technical, and hazardous maintenance required to keep older planes in the sky, are becoming increasingly essential. The 250th repair milestone is not just a company achievement; it is a symptom of a broader industry reliance on specialized MRO providers to bridge the gap caused by new aircraft shortages.

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.

Published

on

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.
