SunExpress and Lufthansa Technik Sign Five-Year Engine MRO Agreement
SunExpress and Lufthansa Technik enter a five-year contract for maintenance of Boeing 737 CFM56-7B and LEAP-1B engines from 2026 to 2031.

This article is based on an official press release from Lufthansa Technik and additional industry data.
SunExpress and Lufthansa Technik Seal “Cross-Generational” Engine Support Deal
SunExpress, the joint venture airline established by Turkish Airlines and Lufthansa, has officially secured the long-term operational stability of its Boeing 737 fleet through a new five-year agreement with Lufthansa Technik. Announced on January 15, 2026, the exclusive contract covers maintenance, repair, and overhaul (MRO) services for both the carrier’s legacy and next-generation engine types.
According to the joint announcement, the agreement spans from 2026 through 2031. It is designed to address the complex “dual-fleet” requirements of modern aviation, covering the CFM56-7B engines that power the airline’s established Boeing 737-800 Next Generation (NG) fleet, as well as the LEAP-1B engines utilized by its expanding Boeing 737-8 (MAX) fleet.
This strategic move ensures that SunExpress retains access to premium MRO slots during a period of high industry demand. The work will primarily be conducted at Lufthansa Technik’s main engine workshops in Hamburg, Germany, with additional support provided by XEOS, a specialized facility in Poland.
Scope of the Five-Year Agreement
The contract represents a comprehensive support package tailored to an airline in the midst of a significant fleet transition. Lufthansa Technik has confirmed that the scope of work includes full overhauls, performance restoration shop visits, and “quick turn” surgical repairs designed to minimize downtime.
Supporting the Legacy Fleet
Despite the industry’s gradual shift toward newer aircraft, the CFM56-7B remains a workhorse for SunExpress. With global supply chain issues delaying the delivery of new jets across the sector, airlines are flying older aircraft longer than originally planned. This agreement secures critical shop capacity for the CFM56-7B, ensuring the 737-800 fleet remains reliable through the end of the decade.
Enabling the Next Generation
Simultaneously, the deal covers the LEAP-1B engines for the Boeing 737 MAX. As SunExpress integrates these more fuel-efficient aircraft, having ordered up to 90 MAX jets in late 2023, the need for specialized next-gen maintenance is rising. Lufthansa Technik noted that this agreement validates their early investment in LEAP capabilities, including the ramp-up of operations at their XEOS facility in Åšroda ÅšlÄ…ska, Poland.

Strategic Context
AirPro News Analysis: The Dual-Fleet Challenge
At AirPro News, we observe that this agreement underscores a critical trend in the 2026 aviation landscape: the “dual-fleet” challenge. Airlines are no longer simply swapping old planes for new ones; they are operating them in parallel for extended periods due to manufacturer delivery delays.
Industry data suggests that shop visits for the legacy CFM56-7B are peaking, with forecasts predicting approximately 1,900 visits annually through 2026. By locking in a five-year exclusive deal with a top-tier provider like Lufthansa Technik, SunExpress is effectively insulating itself from the capacity crunches affecting the broader MRO market. Furthermore, the inclusion of the LEAP-1B engines ensures that the airline’s sustainability goals, driven by the 15-20% fuel efficiency gains of the MAX fleet, are not compromised by maintenance bottlenecks.
Company Backgrounds
SunExpress was founded in 1989 as a joint venture between Turkish Airlines and Lufthansa. It operates as a leisure carrier connecting Europe with Turkey and other holiday destinations. As of early 2026, the airline operates an all-Boeing fleet comprising over 60 737-800s and a rapidly growing number of 737-8 MAX aircraft, targeting a total fleet size of approximately 150 aircraft in the coming decade.
Lufthansa Technik is the world’s leading provider of aircraft maintenance, repair, and overhaul services. A subsidiary of the Lufthansa Group, the company reported revenues of approximately €6.5 billion in 2023. While it shares a parent company with SunExpress, this agreement is a commercial contract that reinforces Lufthansa Technik’s competitive position in the open MRO market.

Honeywell Aerospace Orders Odysight.ai APU Visual Monitoring POC
Honeywell Aerospace and Odysight.ai launch a proof-of-concept for AI visual monitoring on APUs across 10,000+ aircraft.

Odysight.ai has secured a purchase order from Honeywell Aerospace to launch a proof-of-concept for an advanced visual monitoring system designed to enhance predictive maintenance on auxiliary power units.
Announced in a press release on June 18, 2026, the collaboration will evaluate the integration of Odysight.ai’s miniature visual sensors and edge AI analytics within Honeywell Auxiliary Power Units (APUs). The initiative targets the early detection of internal wear and damage, aiming to reduce unplanned downtime across a global installed base of more than 10,000 APUs in commercial and defense fleets.
Visual sensing technology in hard-to-reach areas
The proof-of-concept focuses on deploying ruggedized, miniature cameras in highly inaccessible sections of the APU, such as the air intake. These sensors are designed to provide continuous, real-time internal monitoring between scheduled maintenance intervals.
By capturing visual data from inside the operating unit, the system allows maintenance crews to identify foreign object damage, structural wear, corrosion, and partial flow restrictions before they escalate into critical failures. Odysight.ai Chief Executive Officer Yehu Ofer described the collaboration as an important step for the company.
“With APUs installed across nearly the entire global defense and commercial aircraft fleet, a successful proof of concept could open a compelling pathway to scale across one of the industry’s largest installed bases,” Ofer stated. “We see this as a potential starting point for broader integration opportunities across Honeywell Aerospace aviation portfolio.”
Expanding predictive maintenance footprint
The Honeywell agreement follows a series of recent expansions for Odysight.ai in the aerospace and defense sectors. In January 2026, the Israel-based company received two pilot orders from a major defense customer to monitor aerial platforms, including an operational combat helicopter.
In April 2026, Odysight.ai signed a commercial collaboration agreement with GACI Technologies to introduce its predictive maintenance solutions to the French aerospace market. Concurrently, Honeywell Aerospace has been advancing its own digital maintenance capabilities. Also in April 2026, maintenance provider Revima signed a five-year agreement with Air Astana Group to service Honeywell 131-9A APUs, incorporating digital predictive maintenance tools to optimize lifecycle costs.
AirPro News analysis
We view the integration of visual edge artificial intelligence into APU maintenance as a logical progression in the industry’s shift toward condition-based monitoring. Traditional predictive maintenance relies heavily on vibration, temperature, and pressure sensors, which often detect anomalies only after physical degradation has begun.
By introducing direct visual confirmation into the diagnostic loop, operators can potentially bridge the gap between sensor alerts and physical borescope inspections. If the proof-of-concept proves successful in the harsh operating environment of an APU, it could validate the broader use of embedded visual sensors across other critical aircraft systems, reducing the reliance on routine, labor-intensive teardowns.

Commercial aftermarket demand drives backlog
Commercial services now account for over $170 billion of the company’s total backlog. GE Aerospace reported a 30 percent increase in Commercial Engines and Services (CES) internal shop visit (ISV) revenue over the past 12 months. Spare parts revenue grew by more than 25 percent during the same period.
The manufacturer highlighted the longevity of its CFM56 engine program, noting the average fleet age remains under 15 years. The company projects that 80 percent of CFM56 shop visits over the next few years will come from engines under 20 years old. For newer generation powerplants, GE Aerospace expects the LEAP engine installed base to more than double between 2025 and 2030. In the widebody sector, the GEnx engine program maintains a life-of-program win rate exceeding 75 percent.
“These are encouraging indicators that underlying services demand remains robust. We are confident in our outlook and remain on track to deliver the high end of our full-year guidance.”
The company is scheduled to host its second-quarter earnings call on July 16, 2026, where it will provide further financial details.
Defense portfolio and advanced propulsion milestones
GE Aerospace currently powers two-thirds of United States military combat and rotorcraft fleets. The company hosted a Defense & Propulsion Technologies showcase at its Lynn, Massachusetts facility, where it reported a 30 percent engine output increase in 2025 achieved without additional headcount. The manufacturer projects that advanced defense programs will account for 25 percent of its defense revenue by 2035.
The investor update detailed several advancements in military propulsion programs. GE Aerospace completed the Assembly Readiness Review for the XA102 adaptive cycle engine, advancing the U.S. advanced combat propulsion program to prototype development. In the Collaborative Combat Aircraft (CCA) sector, the U.S. Air Force awarded the company a contract to complete a Preliminary Design Review (PDR) for a medium thrust CCA utilizing the GE426 engine. Concurrently, the GEK1500 engine, developed in partnership with Kratos Defense & Security Solutions for a lower thrust CCA, was selected to move to the PDR phase.
Next-generation technology and AI integration

GE Aerospace demonstrated a generative artificial intelligence application capable of producing a preliminary hypersonic ramjet engine design in seconds, a development intended to compress early design work timelines.
In the electric and hybrid propulsion sector, the manufacturer partnered with BETA Technologies to develop a turbogenerator for the MV250 autonomous military logistics vertical takeoff and landing (VTOL) aircraft. GE Aerospace also completed the first ground test of a megawatt-class hybrid electric engine as part of the National Aeronautics and Space Administration (NASA) Electrified Powertrain Flight Demonstration (EPFD) project.
AirPro News analysis
We note that the 40 percent spike in spare parts orders reflects broader commercial aviation industry constraints. With new aircraft deliveries delayed across the manufacturing sector, operators are investing heavily to keep existing, older fleets operational. The CFM56 data provided by GE Aerospace illustrates this dynamic clearly, as airlines commit to major shop visits for engines that might otherwise have faced retirement in a more fluid delivery environment.
On the defense side, the rapid progression of the GE426 and GEK1500 engines through the Preliminary Design Review phase underscores the U.S. Air Force’s prioritization of the Collaborative Combat Aircraft program. The integration of generative AI into hypersonic ramjet design suggests manufacturers are aggressively seeking ways to shorten the traditional, decades-long military engine development cycle to meet emerging defense requirements.

American Airlines Tulsa Maintenance Base Turns 80
American Airlines marks 80 years of its Tulsa MRO base, now the world’s largest commercial aircraft maintenance facility.

On June 18, 2026, American Airlines (AA) marked the 80th anniversary of its Tech Ops – Tulsa maintenance facility at Tulsa International Airport (TUL), celebrating a site that has grown from a post-war surplus plant into the largest commercial aircraft maintenance base in the world.
In a press release issued to commemorate the milestone, the carrier highlighted the facility’s evolution and its role as the backbone of the airline’s technical operations. The 260-acre complex currently employs nearly 5,000 team members and continues to expand following a series of recent capital investments and workforce additions aimed at supporting the airline’s Boeing 737 and Boeing 787 fleets.
Historical growth and operational scale
The origins of the Tulsa base date back to 1945 when the United States government listed a military aircraft plant as surplus property. American Airlines negotiated a lease with the City of Tulsa and officially opened the maintenance base in 1946, relocating its maintenance and engineering operations from LaGuardia Airport (LGA) in New York.
Today, the property spans more than 260 acres and is anchored by four of the original hangars, which remain in active use. The facility handles a significant portion of the airline’s heavy maintenance, overhaul, and repair work.
Kevin Brickner, Senior Vice President of Technical Operations for American Airlines, praised the workforce in the anniversary announcement, noting that the facility remains a cornerstone of the airline’s aircraft maintenance operation.
“Our team of skilled aviation maintenance professionals in Tulsa and across our system is the best in the business, and they set the standard for safety, quality and ingenuity. We wouldn’t be where we are today without our team members, the City of Tulsa and the State of Oklahoma.”
Recent capital investments and fleet support
The 80th anniversary follows a period of sustained financial investment in the Tulsa infrastructure. In May 2025, the Tulsa Municipal Airport Trust issued a $400 million special facility revenue bond offering, guaranteed by American Airlines Group, to finance major improvements to the overhaul and maintenance base. This funding built upon a December 2023 award of $22 million from the State of Oklahoma’s Business Expansion Incentive Program, which was directed toward an ongoing $350 million improvement project.
These capital improvements have been accompanied by workforce expansion to support specific aircraft types. In September 2024, the airline added 227 aircraft maintenance technicians and more than 100 support staff to the Tulsa base. This personnel increase was designed to establish an additional Boeing 737 overhaul line and facilitate the return of a Boeing 787 heavy maintenance check line to the facility.
To maintain a pipeline of skilled technicians, American Airlines formalized a partnership with Tulsa Tech in 2024. The agreement provides interview opportunities for top students and included the airline’s sponsorship of the school’s adult student team at the 2026 Aerospace Maintenance Council Competition.
AirPro News analysis
The sustained investment in Tech Ops – Tulsa highlights a broader industry trend where major carriers are consolidating heavy maintenance capabilities at established, centralized hubs rather than fragmenting the work across smaller regional stations. By securing municipal bonds and state grants, American Airlines has effectively leveraged public-private partnerships to modernize an 80-year-old footprint without bearing the entire capital expenditure upfront.
Furthermore, bringing a Boeing 787 heavy maintenance check line back to Tulsa indicates a strategic preference for keeping complex, widebody maintenance in-house where the airline has direct oversight of quality control and turnaround times. As the global supply chain for aircraft parts and maintenance, repair, and overhaul (MRO) services remains constrained, maintaining the world’s largest internal commercial aircraft maintenance base provides American Airlines with a distinct operational buffer against external delays.
