Sonex Aircraft Closes Operations Due to Financial Pressures in 2026
Sonex Aircraft halts operations citing financial challenges and FAA MOSAIC rule impact, leaving thousands of kit projects unfinished globally.
This article is based on an official press release from Sonex Aircraft.
On Friday, March 27, 2026, Sonex Aircraft, a cornerstone manufacturers of experimental amateur-built (E-AB) aircraft kits based in Oshkosh, Wisconsin, announced the immediate cessation of its operations. The closure was communicated directly to the aviation community via a video message and a written statement from Owner and President Mark Schaible, marking a sudden end to the company’s decades-long presence in the light sport aircraft market.
According to the company’s official release, the shutdown is the result of insurmountable financial pressures. Schaible cited a severe decline in new kit sales, escalating manufacturing costs, and intense pressure from the company’s bank, which ultimately refused to renew loans or carry forward existing debt. As a result, Schaible confirmed that he and his wife are filing for both business and personal bankruptcy.
The immediate liquidation of Sonex Aircraft sends shockwaves through the homebuilt aviation sector. With thousands of projects currently underway globally, the closure leaves a substantial number of builders with unfulfilled orders and an uncertain future regarding parts and factory support.
The Collapse of a Legacy Manufacturer
A 28-Year History in Oshkosh
Founded in 1998 by John Monnett, Sonex Aircraft built its brand on the philosophy of making aviation accessible and affordable. The company specialized in simple-to-build, metal low-wing aircraft kits. According to historical company data provided in recent industry summaries, Mark Schaible joined the enterprise in 2003, eventually rising to general manager before officially purchasing the company’s assets from Monnett in 2022.
Over its 28-year run, the manufacturer developed a diverse lineup of aircraft, including the original Sonex, the Waiex, the Onex, the Xenos motor glider, and the SubSonex personal jet. Based on the company’s March 2026 figures, approximately 700 Sonex aircraft have been completed and are currently flying, while more than 2,100 projects remain under construction by builders worldwide.
Financial Pressures and Bankruptcy
In his announcement, Schaible outlined the specific financial realities that forced the closure. He pointed to a combination of rising raw material costs, a sharp drop in new orders, and heavy competition from completed Sonex aircraft circulating on the used market.
“A perfect storm of financial pressures.”
Schaible used this phrase in his video address to describe the convergence of economic headwinds that led to the bank’s refusal to extend further credit. He also explicitly compared the financial collapse of Sonex to the high-profile Chapter 11 bankruptcy reorganization of Van’s Aircraft two years prior. However, Schaible noted that Sonex’s situation is significantly more severe, as it has resulted in total liquidation rather than a structured reorganization.
Industry Headwinds and the MOSAIC Effect
Regulatory Shifts Impacting Sales
While internal financial struggles played a critical role, broader regulatory changes have also reshaped the light sport aircraft (LSA) landscape. According to recent industry analysis published by Forbes, the Federal Aviation Administration’s Modernization of Special Airworthiness Certification (MOSAIC) rule has heavily influenced consumer behavior in the kit plane market.
Based on the Forbes reporting, the MOSAIC rule expanded the operational privileges of entry-level sport pilots, allowing them to fly heavier, four-seat legacy aircraft such as the Cessna 172 or Piper Cherokee. Previously, these pilots were restricted to lighter, two-seat aircraft, the exact market segment Sonex dominated. The regulatory shift prompted potential buyers to delay kit purchases or pivot toward larger aircraft. LSA manufacturers like Sonex, lacking the capital to rapidly develop four-seat alternatives, found themselves highly vulnerable to this sudden shift in demand.
Unfulfilled Orders and the Highwing
The closure is particularly devastating for builders invested in the company’s newest model, the Sonex Highwing. According to industry reports, the company had invested heavily in this highly anticipated aircraft, which completed its first flight in June 2025. Sonex had just begun shipping tail kits for the Highwing in January 2026.
Builders who placed deposits or are mid-build are now left with partial kits and lost funds. While Schaible stated that an 11th-hour investment or buyout is highly unlikely, industry sources indicate that the former owner and founder is currently seeking a third party to acquire the company’s assets. The goal of this potential acquisition would be to support the existing Sonex fleet and potentially fulfill outstanding orders for the Highwing model, though no formal agreements have been announced.
AirPro News analysis
The abrupt liquidation of Sonex Aircraft underscores a growing fragility within the experimental amateur-built (E-AB) sector. We are observing a market squeezed on two fronts: unprecedented inflation in raw material and engine costs, and a rapidly shifting regulatory environment. The FAA‘s MOSAIC rule, while widely celebrated for deregulating pilot privileges, has inadvertently cannibalized the traditional two-seat LSA market. Legacy kit manufacturers operating on thin margins are struggling to pivot their engineering and production lines fast enough to meet the new consumer appetite for heavier, four-seat aircraft. Sonex’s closure, following closely on the heels of the Van’s Aircraft reorganization, suggests that the era of budget-friendly, entry-level kit manufacturing may be undergoing a painful, permanent contraction.
Frequently Asked Questions
What happened to Sonex Aircraft?
On March 27, 2026, Sonex Aircraft announced its immediate closure due to insurmountable debt, a drop in sales, and rising manufacturing costs. The owner is filing for both business and personal bankruptcy.
Will outstanding kit orders be fulfilled?
As of the closure announcement, operations have ceased immediately, leaving outstanding orders unfulfilled.

FL Technics Indonesia Earns EASA Part-145 Certification in Bali
FL Technics Indonesia receives EASA Part-145 approval for its Bali MRO facility, covering A320 and Boeing 737 maintenance.
FL Technics Indonesia has secured European Union Aviation Safety Agency (EASA) Part-145 certification for its maintenance, repair, and overhaul (MRO) facility at I Gusti Ngurah Rai International Airport (DPS) in Bali. The approval, announced on October 26, 2026, authorizes the provider to perform base and line maintenance on aircraft registered in the European Union.
The certification positions the Indonesian subsidiary as one of the few MRO providers in the country capable of servicing European carriers and other operators that mandate EASA-approved maintenance standards. According to a press release issued by the company, the approval covers the globally ubiquitous Airbus A320 family, including both CEO and NEO variants, alongside Boeing 737 Classic, Next-Generation (NG), and MAX aircraft.
Expanding capacity for European and international fleets
The regulatory approval follows a series of comprehensive technical and quality audits conducted by EASA inspectors. These evaluations assessed the hangar infrastructure, tooling systems, and the engineering workforce at the Bali site to ensure compliance with European aviation safety regulations.
With the certification secured, the facility is scheduled to commence maintenance work for its first European Union-based operator in early November 2026. Additional aircraft arrivals from European operators are expected later in the month.
Martynas Grigas, Chairman of FL Technics Indonesia, highlighted the immediate impact of the regulatory milestone:
“The facility is preparing to start the work for an EU-based operator by next week, with further arrivals expected in November 2026. FL Technics Indonesia is also positioned to serve operators across Asia, the Middle East, and Australia that require EASA-approved maintenance.”
Prior to receiving the EASA certification, the Bali facility had already been providing maintenance solutions for aircraft registered across the Americas, Asia, Africa, and Australia. The new approval allows the company to capture maintenance demand from European carriers operating in or flying to the Asia-Pacific region.
Building the Bali maintenance hub
The development of the Bali facility was initiated on August 17, 2023, through a joint operations agreement between FL Technics, PT Angkasa Pura Properti, and PT Angkasa Pura I. FL Technics committed an initial investment of US$25 million to construct the MRO hub, designed to serve the growing maintenance needs for narrowbody aircraft in the Asia-Pacific region.
The 17,000-square-meter facility officially opened on November 29, 2024. It features a 2,000-square-meter purpose-built paint booth. The October 26, 2026, announcement describes the site as featuring three hangars with three aircraft bays, though earlier company statements at the time of its 2024 opening referenced a six-bay maintenance capacity.
FL Technics global footprint
FL Technics Indonesia, operating legally as PT Avia Technics Dirgantara, is a subsidiary of FL Technics, which is itself part of the Avia Solutions Group. The EASA certification in Bali represents a continuation of the parent company’s strategy to expand its global hangar network and capture a larger share of the international narrowbody maintenance market.
The company operates a network of hangars across multiple continents. In addition to its Indonesian facilities in Jakarta and Bali, FL Technics maintains operations in Prestwick, United Kingdom; Vilnius and Kaunas, Lithuania; and Punta Cana, Dominican Republic. The company has also pursued growth through acquisitions, notably purchasing Czech MRO provider JOB AIR Technic in June 2025 to add significant capacity in Central Europe.
AirPro News analysis
Securing EASA Part-145 certification in Southeast Asia provides FL Technics with a distinct strategic advantage. As global narrowbody fleets expand and MRO slots in Europe and North America remain heavily constrained, European airlines and lessors are increasingly looking further afield for heavy maintenance capacity. A certified facility in Bali allows European operators to utilize lower-cost, high-quality maintenance in the Asia-Pacific region, which is particularly valuable for aircraft transitioning between lessees or undergoing heavy checks.
Furthermore, EASA certification acts as a global gold standard. Many operators in the Middle East, Africa, and Australia mandate EASA-approved maintenance in their contracts, even if their aircraft are not registered in the European Union. By elevating the Bali facility to this regulatory standard, FL Technics effectively unlocks a much broader international customer base beyond its immediate geographic region.

Embraer Renews Component Support Deal With Alliance Airlines
Embraer and Alliance Airlines extend a Component Support Agreement for 40 E190s, contributing to a record US$5.6B services backlog.
Embraer S.A. and Alliance Airlines have renewed a long-term Component Support Agreement to provide ongoing maintenance and repair solutions for 40 Embraer E190 aircraft operating in Australia.
Announced on October 21, 2026, the contract extension secures supply chain stability for Australia’s largest E-Jet operator. The agreement ensures component availability for a fleet heavily utilized in regional connectivity and specialized charter operations. According to Embraer, the deal directly contributed to the manufacturer’s record third-quarter services backlog.
Securing operational reliability for FIFO networks
Alliance Airlines operates a highly specialized network as Australasia’s leading provider of Aircraft, Crew, Maintenance, and Insurance (ACMI) services, alongside contract and charter flights. A significant portion of the carrier’s operations supports the Australian mining, energy, and government sectors through Fly-in Fly-out (FIFO) services. These operations require high dispatch reliability in remote and demanding environments, where schedule disruptions can severely impact resource extraction and industrial projects.
To maintain operational standards, Alliance Airlines holds the International Air Transport Association (IATA) Operational Safety Audit (IOSA) certification and maintains Flight Safety Foundation “BARS Gold” status. The renewed Component Support Agreement guarantees the airline access to Embraer’s global inventory of spare parts and repair capabilities. By pooling component resources, the airline can minimize aircraft downtime, streamline its supply chain, and manage maintenance costs predictably across its expansive network.
Carlos Naufel, President and CEO of Embraer Services & Support, highlighted the operational impact of the fleet in a press release issued on October 21, 2026.
Alliance Airlines’ E-Jets have been instrumental in enhancing Australia’s regional connectivity. As the airline grows, we remain committed to providing the maintenance solutions, expertise and support needed to keep the E190s performing at the highest levels every day.
Embraer’s growing aftermarket backlog
The Alliance Airlines renewal aligns with a broader expansion of Embraer’s aftermarket business. On October 23, 2026, the Brazilian manufacturer reported a record company-wide order backlog of US$35.7 billion for the third quarter of 2026.
Within that total, the Services & Support division reached its own all-time high backlog of US$5.6 billion, representing a 14 percent year-over-year increase. Embraer explicitly cited the Alliance Airlines contract as a key contributor to this financial milestone.
The manufacturer has actively pursued similar maintenance contracts globally to secure long-term revenue streams from its mature aircraft programs. In a comparable recent transaction highlighted in the third-quarter financial results, Embraer signed a Component Pool Program Agreement with Portugália Airlines to support its fleet of 19 Embraer E190 aircraft. These agreements demonstrate a concerted effort by Embraer to retain aftermarket market share as its first-generation E-Jet aircraft transition to secondary operators.
Alliance Airlines and the Australian E-Jet market
Asia-Pacific represents a foundational market for Embraer in the Australia region. The manufacturer delivered its first aircraft to an Australian customer in 1978. Today, approximately 70 E-Jets are in service across six different Australian operators, heavily supporting the country’s critical FIFO operations and regional airline networks.
Alliance Airlines introduced the Embraer E190 to its fleet in 2021. The carrier rapidly expanded its reliance on the type to support both its independent charter operations and wet lease agreements with major domestic carriers, including Qantas and Virgin Australia.
To fuel this expansion, Alliance Airlines has aggressively acquired secondary market airframes. On February 27, 2023, the airline announced an agreement to purchase 30 additional Embraer E190 aircraft from aviation lessor AerCap. These aircraft, previously operated by a North America-based airline, were scheduled for delivery through January 2026.
While Alliance Airlines owns more than 60 Embraer E190s in total, the newly renewed Component Support Agreement specifically covers an active fleet of 40 operational aircraft. The remaining airframes in the carrier’s inventory are utilized for spare parts, undergo heavy maintenance, or await certification for service entry in Australia.
AirPro News analysis
The renewal of this Component Support Agreement underscores a strategic shift in how regional aircraft manufacturers manage the lifecycle of their products. As the Embraer E190 transitions deeper into the secondary market, Embraer is successfully capturing aftermarket revenue by offering original equipment manufacturer (OEM) backed support to operators acquiring used airframes. For Alliance Airlines, the Embraer E190 has proven to be an ideal platform for the Australian mining sector. The aircraft offers the payload and range required for remote Fly-in Fly-out operations while maintaining economics that support Aircraft, Crew, Maintenance, and Insurance (ACMI) and charter business models. By locking in component support directly with the manufacturer, Alliance Airlines mitigates the supply chain risks associated with operating a mature aircraft variant in a high-utilization environment. We view this agreement as a mutually beneficial model that secures Embraer’s services backlog while stabilizing operational costs for Australia’s largest E-Jet operator.

Baxter Aerospace Invests $19.55M in Utah Manufacturing Facility
Baxter Aerospace expands into Washington County, Utah with a $19.55M facility to scale UAS and satellite comms production.
Baxter Aerospace will invest $19.55 million to lease and equip a new manufacturing facility in Washington County, Utah, transitioning its unmanned aircraft and communications systems from prototype development into full-scale production.
The expansion, announced in an October 8, 2026, press release by the Utah Governor’s Office of Economic Development (GOED), is projected to create 90 high-paying jobs over the next five years while strengthening the state’s aerospace and defense industrial base.
Transitioning to full-scale production
The new facility in Washington City will feature high-capacity infrastructure, specialized testing spaces, and security systems. This site is designed to support mission-critical work across aerospace, defense, satellite communications, autonomous aircraft, and public safety.
Baxter Aerospace CEO Jeff Baxter stated that expanding in southern Utah allows the company to increase manufacturing capacity and support growing customer needs. He noted the company is prepared to help shape the region’s aerospace future.
The project is backed by a Rural Economic Development Tax Increment Financing (REDTIF) post-performance tax credit approved by the GOED. Under the agreement, Baxter Aerospace can earn a rebate of up to 30% on new state revenues generated over the five-year term, capped at $456,939.
State officials project the expansion will generate $20,758,160 in new state wages and $1,523,131 in new state tax revenue during that period. GOED Commissioner Jefferson Moss noted that the investment signals Utah’s economic future is fueled by frontier innovation. Washington County Commissioner Adam Snow added that the expansion connects local talent with emerging aerospace opportunities.
Scaling the BA-1 Dragonfly and defense portfolio
The manufacturing expansion follows a period of steady growth for the St. George-based defense and aerospace innovator. Brothers Jeff and Michael Baxter founded the company in 2015 following a severe Oregon wildfire, focusing their initial efforts on real-time sensing, resilient communications, and autonomous systems for emergency response and defense applications.
The company’s flagship aerospace product is the BA-1 Dragonfly. The Dragonfly is a Group 3 vertical takeoff and landing (eVTOL) unmanned aircraft system designed for intelligence, surveillance, and reconnaissance (ISR) missions, featuring over 12 hours of endurance.
Alongside the BA-1 Dragonfly, Baxter Aerospace produces deployable broadband satellite communications kits that utilize low Earth orbit (LEO) networks. The company also manufactures precision components for the fusion and nuclear energy sectors.
To support the scaling of these product lines, Baxter Aerospace secured a $6 million Series A funding round in July 2025. The capital was raised from the Department of Defense (DoD) Accelerator fund, managed by Accuidity Capital Management, specifically to accelerate production of the Dragonfly system and the deployable communications kits. The new Washington County facility represents the physical infrastructure required to execute that production scale-up between late 2026 and 2031.
