Daher Wins 2026 JEC Innovation Award for Thermoplastic Wing Rib

On January 12, 2026, the French industrial conglomerate Daher was announced as the winner of the prestigious 2026 JEC Composites Innovation Award in the “Aerospace – Parts” category. The award recognizes the company’s development of a “Highly Loaded Thermoplastic Wing Rib,” a critical structural component designed to meet the rigorous demands of future single-aisle Commercial-Aircraft programs.

According to the company’s announcement, this innovation represents a significant leap forward in the application of thermoplastic composites. While previous applications were often limited to thinner, secondary parts, this project demonstrates the viability of thermoplastics for thick, primary aerostructures that must withstand heavy mechanical loads.

Breaking Boundaries in Composite Manufacturing

The award-winning component is a structural breakthrough for the aerospace industry. Traditionally, primary structures like wing ribs, which maintain the aerodynamic shape of the wing and transfer loads between the skin and spars, have been manufactured using aluminum or thermoset composites that require lengthy autoclave curing cycles.

Daher’s new rib is a thick laminate structure consisting of up to 64 plies, reaching a thickness of approximately 12mm. By successfully manufacturing a part of this density and complexity using thermoplastics, Daher has proven that the material can replace metal in the most demanding areas of an airframe.

Collaborative Development

The project was executed through a strategic consortium involving several key European partners, each contributing specialized expertise to the Manufacturing chain:

• Victrex (UK): Supplied the specific material, a Carbon Fiber Reinforced Thermoplastic (CFRTP) using LMPAEK (Low Melt Polyaryletherketone) unidirectional tape.
• LIST (Luxembourg): Developed a novel Infrared (IR) welding process to assemble the rib.
• CETIM (France): Designed the mechanical test bench to validate the component under flight-certification loads.
• AniForm (Netherlands): Provided advanced simulation Software to predict distortion and ensure “first-time-right” manufacturing.

Technical Innovations and Process Efficiency

The success of the “Highly Loaded Thermoplastic Wing Rib” relies on the integration of two patented processes that streamline production and eliminate traditional manufacturing bottlenecks.

First, the rib utilizes Direct Stamping®, a Daher-patented process. According to the press release, this technique eliminates the intermediate “consolidation” step typically required between layering fibers (layup) and the stamping phase. By removing this step, the production cycle is significantly shortened, and energy consumption is reduced.

Second, the assembly utilizes Infrared (IR) Welding, a patent held by the Luxembourg Institute of Science and Technology (LIST). Instead of using heavy metal rivets or bolts to assemble the rib’s T-shaped profile, the partners used IR welding to create a continuous, integrated composite structure. This approach eliminates the weight of fasteners and improves the overall integrity of the part.

“This JEC Award rewards our commitment to advancing composite technologies for aeronautics. We believe in it: by combining innovative materials and advanced processes, we demonstrate that it is possible to combine performance, competitiveness, and reduction of the carbon footprint.”

Performance Metrics and Environmental Impact

The shift to thermoplastics and the elimination of fasteners has yielded quantifiable performance improvements. Data provided by Daher highlights the following metrics for the new wing rib compared to traditional aluminum or bolted metal assemblies:

• Weight Reduction: The component is 22% lighter than its aluminum equivalent.
• Cost Efficiency: Assembly costs are reduced by 15% compared to bolted metal solutions.
• Production Speed: The overall production cycle time is reduced by 25%.
• Sustainability: The technology saves an estimated 12.5 tons of CO₂ per rib over the lifecycle of a single-aisle aircraft.

AirPro News Analysis

The significance of this award extends beyond a single component; it addresses the “holy grail” of next-generation aircraft manufacturing: rate. As Airbus and Boeing look toward successors for the A320 and 737 families, they face the requirement of producing wings at unprecedented rates, potentially 75 to 100 aircraft per month.

Traditional thermoset composites, while light, are chemically slow to cure, creating a bottleneck in the factory. Thermoplastics, which can be stamped, melted, and welded in minutes, are widely viewed as the necessary enabler for these high-rate programs. By demonstrating that thermoplastics can handle the structural loads of a primary wing rib, Daher is positioning itself as a critical supplier for the “Wing of Tomorrow.” Furthermore, the use of induction welding (seen in their 2025 Torsion Box project) and now IR welding suggests Daher is building a diverse toolkit of joining technologies to eliminate rivets entirely from future airframes.

Frequently Asked Questions

What is LMPAEK?

LMPAEK stands for Low Melt Polyaryletherketone. It is a high-performance thermoplastic polymer that offers high heat resistance and mechanical strength but can be processed at lower temperatures than traditional PEEK, making it faster and more energy-efficient to manufacture.

Why is Infrared (IR) welding important?

IR welding allows for the assembly of composite parts without mechanical fasteners like rivets or bolts. This reduces the overall weight of the aircraft and eliminates the labor-intensive process of drilling thousands of holes, which speeds up production.

What is the primary advantage of thermoplastics over thermosets?

Unlike thermosets, which undergo a permanent chemical change during curing and cannot be reshaped, thermoplastics can be melted and reshaped multiple times. This makes them recyclable and allows for much faster manufacturing cycles (minutes vs. hours).

ASG Helicopters Services Introduces First Leonardo AW189 to Caspian Region

ASG Helicopter Services (ASG), a prominent aviation operator based in Azerbaijan, has officially integrated its first Leonardo AW189 helicopter into its fleet. The delivery, celebrated during a presentation on December 17, 2025, marks a significant operational milestone as the first aircraft of its type to enter service in the Caspian Sea region, covering Central Asia and the Caucasus.

According to the company’s announcement, this delivery is the first of two units ordered to support offshore oil and gas operations. The second unit is scheduled for delivery in early 2026. The acquisition was executed through a partnership involving ASG, the manufacturer Leonardo Helicopters, and Exclases Group, the exclusive distributor for Leonardo in the region.

Operational Capabilities and Configuration

The newly delivered AW189 has been supplied in a specialized offshore configuration designed to meet the rigorous demands of the energy sector. ASG Helicopter Services states that the aircraft is tailored for long-range transport and overwater safety, bridging the operational gap between the company’s medium-class AW139s and heavy-class Sikorsky S-92As.

The “super-medium” class helicopter features a maximum take-off weight (MTOW) of approximately 8.3 to 8.6 tonnes and is configured to carry 16 passengers plus two pilots. Key safety specifications highlighted in the release include a main gearbox capable of a 50-minute “run-dry” operation, exceeding standard certification requirements, and a Full Ice Protection System (FIPS) to manage the challenging winter conditions of the Caspian region.

Strategic Fleet Modernization

ASG Helicopter Services indicated that the introduction of the AW189 is part of a broader strategy to modernize its fleet and enhance service offerings for major clients such as SOCAR, BP, and TOTAL. By adopting the super-medium platform, the operator aims to provide a more cost-efficient solution for missions that require significant range and payload but do not necessitate the full capacity of a heavy helicopter.

Azer Sultanov, Head of ASG Helicopter Services, emphasized the importance of this acquisition for the company’s future operations:

“Next-generation helicopters represent a significant new era for ASG Helicopter Services. The integration of the AW189 helicopter into our offshore operations strengthens our capability to meet the evolving needs of customers in the oil, gas, and energy sectors, while ensuring the highest standards of safety, reliability, and operational efficiency.”

The company confirmed that the aircraft has already received all necessary registration and airworthiness certificates from the Civil Aviation Authority of Azerbaijan.

AirPro News analysis

The arrival of the AW189 in the Caspian region reflects a wider global trend in the offshore energy sector: the shift toward “super-medium” rotorcraft. For years, the industry relied heavily on heavy helicopters for deep-water transport. However, volatility in oil prices and advancements in avionics have driven operators toward aircraft that offer near-heavy payload capabilities with the lower operating costs of a medium airframe.

By securing the first AW189 in the region, ASG positions itself as a technological leader in the Central Asian market. This move likely anticipates stricter safety standards from International Oil and Gas Producers (IOGP), which increasingly favor modern airframes equipped with advanced terrain awareness and run-dry capabilities. We expect this acquisition to place pressure on regional competitors to upgrade their legacy fleets to maintain contracts with international oil majors.

AAR Corp. to Close Indianapolis Maintenance Hub, Impacting 329 Workers

AAR Corp. (NYSE: AIR) has confirmed plans to permanently shutter its airframe maintenance facility at the Indianapolis International Airport (IND), a move that will result in the layoff of approximately 329 employees. According to a Worker Adjustment and Retraining Notification (WARN) Act notice filed with the Indiana Department of Workforce Development on December 22, 2025, the closure is scheduled to take place in phases over the next year.

The decision marks the end of a two-decade era for the facility under AAR’s management. Reporting by IndyStar indicates that the closure aligns with the expiration of the company’s lease and follows a significant strategic shift in AAR’s North American operations. The shutdown process is set to begin on February 15, 2026, and is expected to conclude by February 28, 2027.

Strategic Consolidation Following HAECO Acquisition

The closure of the Indianapolis site appears to be a direct consequence of AAR’s recent expansion efforts elsewhere. In November 2025, AAR finalized the acquisition of HAECO Americas for a reported $78 million. This transaction provided the aviation services company with two modern heavy maintenance facilities located in Greensboro, North Carolina, and Lake City, Florida.

According to industry analysis and financial reports, the HAECO acquisition included approximately $850 million in long-term contracts, effectively securing capacity at the newly acquired sites. Consequently, the Indianapolis facility, a legacy asset requiring a lease renewal, was deemed redundant within the optimized network.

Facility Condition and Lease Timing

The Indianapolis Maintenance Center, located at 2825 W. Perimeter Road, is a massive 1.6 million-square-foot complex originally constructed in the early 1990s. AAR leased approximately 367,000 square feet of this space. Reports suggest that the aging infrastructure of the facility, often described in local aviation circles as “legacy” compared to modern standards, played a role in the decision.

AAR’s lease with the Indianapolis Airport Authority (IAA) was approaching expiration. Rather than committing to a long-term renewal, the company signed a short-term extension through February 2027. This timeline mirrors the final closure date outlined in the WARN notice, signaling a deliberate exit Strategy rather than a sudden financial collapse.

Impact on Workforce and Local Economy

The primary impact of this consolidation will be felt by the local workforce. The WARN notice specifies that 329 employees will be separated from the company starting in mid-February 2026. AAR has stated that all affected employees are receiving at least 60 days’ notice, complying with federal requirements.

The Indiana Department of Workforce Development is expected to activate its “Rapid Response” team to assist displaced workers. This state-led initiative typically provides job placement assistance, resume workshops, and Training opportunities to help workers transition to new employment.

Historical Context of the Site

The Indianapolis Maintenance Center has a complex history tied to public investment. Originally built for United Airlines in 1994, the facility was supported by over $300 million in taxpayer incentives with the promise of thousands of jobs. However, United Airlines vacated the site in 2003 following bankruptcy proceedings.

AAR took over the facility in 2004, stabilizing the site and employing hundreds of mechanics for over 20 years. The upcoming departure leaves the Indianapolis Airport Authority with a significant vacancy, specifically 10 hangar bays, that has historically been difficult to fill.

Financial Health and Market Trends

Despite the closure, AAR Corp. remains in a strong financial position. Fiscal Year 2025 reports indicate a 20% revenue growth, reaching $2.8 billion. This growth has been driven largely by acquisitions and robust demand for aftermarket parts. The company’s stock performance has trended upward, with analysts interpreting the consolidation of operations into the HAECO facilities as a margin-positive move.

AirPro News Analysis

The closure of the Indianapolis facility underscores a broader trend in the MRO sector: the prioritization of owned, modern assets over leased legacy infrastructure. By acquiring HAECO, AAR not only gained capacity but also secured a workforce and facility footprint that likely offers better long-term economics than the aging Indianapolis site.

For the Indianapolis Airport Authority, this presents a familiar challenge. The facility was designed for a different era of aviation, where massive, single-tenant hubs were the norm. In today’s market, finding a single tenant to occupy such a vast space is increasingly difficult. We anticipate the IAA may need to subdivide the space or seek non-traditional tenants to utilize the hangars effectively once AAR departs in 2027.

Frequently Asked Questions

When will the layoffs begin?
According to the WARN notice, the first separations are scheduled to begin on February 15, 2026.

Is AAR Corp. in financial trouble?
No. Financial reports show AAR is growing, with a 20% revenue increase in FY2025. The closure is a strategic move to consolidate operations following the acquisition of HAECO Americas.

What will happen to the facility?
The facility will revert to the control of the Indianapolis Airport Authority after the lease expires in February 2027. The IAA has not yet announced specific plans for the site.
