A major focal point for the company is MTU Maintenance Fort Worth. The Texas-based facility is transitioning from a dedicated on-site service specialist to a comprehensive disassembly, assembly, and testing (DAT) facility. The press release notes that its core programs will feature CFM International’s LEAP engine and GE Aerospace’s GEnx. The first induction of the LEAP-1B variant is scheduled for mid-2026.

In Europe, MTU Maintenance Berlin-Brandenburg has expanded its PW800 engine program to encompass comprehensive engine MRO. Meanwhile, the Ludwigsfelde location is constructing a new production facility to boost IGT capacities, targeting a 30 percent increase in shop-visit volume in the coming years.

Further east, EME Aero, MTU’s joint venture with Lufthansa Technik in Poland, inducted its 1,000th engine and inaugurated a second test cell. The facility expects to reach an operating volume of 500 shop visits per year starting in 2028. Additionally, MTU Maintenance Serbia is ramping up operations, aiming for an estimated 470,000 annual working hours by 2029.

Asia-Pacific and Ancillary Services

In the Asia-Pacific region, MTU Maintenance Zhuhai opened a secondary production facility in Jinwan dedicated to the PW1100G-JM program. Once fully ramped up, the combined annual capacity of the two Zhuhai sites will exceed 700 shop visits, according to the company.

MTU’s ancillary services also saw notable growth. The ON-SITEPlus service network attended over 1,000 events in 2025. Furthermore, MTU Maintenance Lease Services grew its operations by 20 percent, recording more than 90 transactions and expanding its lease pool to 140 assets, including newly added LEAP and GEnx engines.

AirPro News analysis

We observe that the 18 percent revenue jump and strategic facility expansions highlight the aviation industry’s ongoing reliance on established MRO providers to keep both legacy and next-generation engines on wing. As supply chain constraints continue to challenge new aircraft deliveries, we believe robust MRO networks like MTU’s are critical for airlines seeking to maximize the lifespan of their existing fleets. The aggressive ramp-up of LEAP and GTF capabilities indicates a clear industry pivot toward supporting the latest narrowbody workhorses.

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.

Expanding global conversion capacity

Ascent Aviation Services, an independent aircraft aftermarket service provider and Federal Aviation Administration (FAA) Class IV Part 145 certified repair station, will operate two parallel conversion lines at its Pinal Air Park campus. To accommodate the Boeing 777-300ERSF program, the company invested $70 million to construct two 90,000-square-foot widebody hangars. Ascent broke ground on the facilities on March 29, 2024, effectively tripling the site’s hangar capacity.

“The launch of Boeing 777-300ERSF conversions in North America marks an important milestone for IAI’s global conversion program,” Yaacov Berkovitz, executive vice president and general manager of IAI Aviation Group, stated in the release. “Together with Ascent Aviation Services, we are expanding production capacity and bringing our conversion capabilities closer to customers in the region.”

Ascent Aviation Services chief executive officer David Querio noted that the induction represents the beginning of a long-term partnership with IAI, with multiple Boeing 777-300ERSF conversions planned for the Marana site.

“Our vision is to shape the future of aviation by turning engineering innovation into lasting value for our customers,” IAI president and chief executive officer Guy Bar Lev added. “Passenger-to-freighter conversions are a key part of that vision, extending the productive life of aircraft and helping airlines adapt to changing market needs.”

World Star Aviation’s fleet strategy

The inaugural aircraft belongs to World Star Aviation, a full-service aircraft and engine lessor headquartered in London. The company specializes in mid-to-late life assets and manages a portfolio of approximately 150 aircraft and engines. This includes 60 narrowbody and widebody freighters currently on lease to cargo operators globally.

World Star Aviation partner Yoyo Allalouf cited the strength of the IAI program during a critical period for widebody passenger-to-freighter production as the primary driver for their selection.

“IAI’s dominance in the widebody P2F space, demonstrated by its Boeing 747 and 767 programs, together with our long-standing relationship, underpinned our decision to choose IAI for the 777-300ERSF,” added Garreth Slevin, partner at World Star Aviation.

The rise of the “Big Twin” freighter

The Boeing 777-300ERSF program, marketed as “The Big Twin,” launched on October 22, 2019, as a joint venture between IAI and GECAS, which was subsequently acquired by AerCap. It remains the only certified P2F conversion program for the Boeing 777-300ER.

The converted freighter offers 25 percent more cargo volume than a production Boeing 777-200LRF and 15 percent more volume than a Boeing 747-400BCF. This capacity positions the aircraft as a direct replacement for aging Boeing 747-400 and McDonnell Douglas MD-11 freighter fleets.

IAI brings over 50 years of experience to the program, having delivered more than 350 converted cargo aircraft across Boeing 747, 767, 737, and Airbus A330 platforms. The company currently holds a dominant market share in medium-size freighter conversions, particularly with the Boeing 767.

The 777-300ERSF recently transitioned from certification into commercial service. In August 2026, Challenge Group took delivery of its second 777-300ERSF, which marked the fifth redelivery of the type across the industry for the year.

AirPro News analysis

We view the activation of the Marana conversion lines as a critical step in maturing the Boeing 777-300ERSF program. By establishing a North American footprint, IAI mitigates geographic bottlenecks and provides operators with a domestic option for heavy modifications. The $70 million infrastructure investment by Ascent Aviation Services indicates strong long-term confidence in the widebody conversion market, even as the air cargo sector normalizes following pandemic-era peaks. As legacy quad-engine and tri-engine freighters approach mandatory retirement or become economically unviable, the availability of parallel conversion lines in the United States ensures IAI can capture a significant share of the impending widebody replacement cycle.

Centralizing certification operations

The Engine Run-Up Center will consolidate several final-phase manufacturing steps into a single enclosed building. The facility will house two calibration stalls dedicated to engine setup and testing, utilizing an 8-foot exhaust collector to ventilate the spaces. A separate climate-controlled control room will allow technicians to conduct data analysis during the testing phase.

In addition to the testing stalls, the building will include two stalls specifically engineered for fueling and defueling aircraft. These areas incorporate specialized fire protection systems and are designed to meet requirements for handling flammable fluids.

Cirrus Chief Executive Officer Zean Nielsen stated that engine run-ups and fuel system calibration are essential processes across aircraft manufacturing. He noted that the modern facility will allow the company to streamline these critical operations, improve efficiency, and provide team members with a dedicated environment to perform the work.

Expanding the Duluth manufacturing footprint

The new testing center adds to an existing corporate footprint that exceeds 1.3 million square feet. The majority of this infrastructure is located in Duluth, which serves as the primary production hub for the manufacturer.

Founded in 1984 and now publicly traded on the Hong Kong Stock Exchange, Cirrus has manufactured more than 12,000 SR Series piston aircraft and Vision Jets to date. The groundbreaking follows closely on a major program milestone for the company. On October 21, 2026, Cirrus celebrated the 10-year anniversary of Federal Aviation Administration (FAA) type certification for the Vision Jet, the first single-engine personal jet to reach the market.

Patrick Waddick, President of Innovation & Operations at Cirrus, highlighted the scale of the company’s historical output in Duluth. He noted that the new facility expands a footprint where the company has produced its entire fleet of over 12,000 aircraft, adding that the manufacturer has spent decades challenging conventions through innovations that transform personal aviation.

Project timeline and operational impact

Construction on the Engine Run-Up Center is underway, with the facility expected to open and become fully operational by the summer of 2027. By moving engine testing indoors, the company anticipates a reduction in noise levels for the surrounding airport environment, a common challenge for manufacturers conducting high-power engine runs on open ramps.

The $8 million investment reflects broader efforts by the airframer to scale production capabilities in response to market requirements. Nielsen indicated that as the company continues to grow, investments in manufacturing infrastructure position Cirrus to meet customer demand while maintaining high standards of quality and safety.
