TAP Air Portugal (TP) and AkzoNobel Aerospace Coatings have concluded operational trials of a new lightweight aircraft basecoat, achieving a 24-kilogram weight reduction on an Airbus A320 and prompting a planned fleet-wide rollout.

Announced in a joint press release on July 28, 2026, the Aerobase UPD formulation eliminates a full paint cycle and reduces total basecoat film thickness by 36 percent compared to traditional two-coat applications. The technology targets incremental weight reductions to lower fuel consumption and carbon emissions across Commercial-Aircraft operations.

Technical enhancements and paint shop efficiency

The Aerobase UPD system utilizes a validated cross-coat application technique that achieves required hiding power and finish quality in a single basecoat cycle. This eliminates the need for a second full basecoat layer and its associated flash-off stages. The simplified process removes an entire paint cycle, increasing operational productivity for applicators.

According to AkzoNobel, the enhanced formulation delivers approximately 40 percent greater sag resistance than traditional two-layer systems. This improvement is designed to increase consistency and repeatability across varying paint shop conditions and applicator experience levels. The product is certified to AMS3095 standards for global mixed-fleet Maintenance, Repair, and Overhaul (MRO) operations and integrates with existing Aerobase activators and hardeners.

“By reducing total film build and simplifying the application process, Aerobase UPD helps operators lower aircraft weight, improve paint shop productivity and maintain the high-quality finish standards required across commercial aviation fleets,” said Aurore Bournazel, Segment Manager OEM, MRO & Airlines at AkzoNobel Aerospace Coatings.

Fleet-wide economic and environmental projections

Field testing on a TAP Air Portugal Airbus A320 confirmed a 24-kilogram weight reduction, nearing the maximum 26-kilogram reduction projected for the technology. Following the initial trial, the Airlines has recoated a second Airbus A320 and is developing rollout plans to extend the lightweight basecoat across its fleet.

Based on projected fleet-wide implementation, TAP Air Portugal estimates the lighter coating will save approximately 428.5 tonnes of fuel annually. This reduction translates to more than 500,000 euros in annual cost savings and an estimated decrease of 1,353 tonnes of carbon dioxide emissions.

“The results achieved through this collaboration with AkzoNobel Aerospace Coatings demonstrate how relatively small weight reductions, when applied consistently across aircraft fleets, could contribute to meaningful long-term fuel and emissions savings, while also supporting operational efficiency,” said João Carvalho, Structures Engineer at TAP Air Portugal.

We view this development as a clear example of how airlines are targeting marginal gains to meet stringent decarbonization targets. While a 24-kilogram reduction on a narrowbody aircraft like the Airbus A320 represents a fraction of its maximum takeoff weight, the cumulative effect across thousands of flight cycles yields material financial and environmental benefits. For European carriers operating under the European Union Emissions Trading System (EU ETS), reducing fuel burn directly lowers compliance costs. The elimination of a full paint cycle also offers MRO providers a tangible reduction in aircraft downtime, which is a critical metric in current constrained maintenance environments.

Bell Textron Inc. has concluded a series of extreme cold weather and icing evaluations for the Bell 525 Relentless in Canada and Michigan, validating the aircraft’s Ice Protection System and performance in austere environments.

Announced in a press release on July 28, 2026, the test campaigns are designed to demonstrate compliance with Federal Aviation Administration (FAA) certification regulations and prepare the helicopter for real-world operations. The environmental testing represents a planned capability expansion beyond the aircraft’s initial type certification.

Validating the Ice Protection System in extreme environments

The flight test team deployed to Yellowknife, Canada, and Marquette, Michigan, to subject the Bell 525 to extreme cold, snow, high altitude, and icing conditions. Yellowknife provided the team with reliable access to temperatures as low as minus 40 degrees, along with the clear flying days necessary for the evaluations.

During the deployments, engineers evaluated engine and system start-up sequences, warm-up behavior, and overall handling qualities in dense, cold air. Doug Hamelwright, 525 Deputy Chief Engineer, noted that the aircraft performed very well during these assessments and emphasized that FAA regulations require operators to validate aircraft performance in every condition the aircraft may encounter.

The campaigns also served to mature the helicopter‘s Ice Protection System (IPS). Test Pilot Pat Lindauer explained that the seasonal testing allowed the team to refine both hardware and software within the IPS control system to meet target performance and reliability metrics.

The U.S. Army Redstone Test Center provided critical support during the icing evaluations. Lindauer credited the center with supplying essential icing test expertise that guided the Bell team through the program safely.

Our focus was to demonstrate compliance with certification regulations and mature the aircraft for real-world customer use. Beyond initial type certification, we completed additional campaigns in extreme cold, snow, high altitude and icing to ensure the aircraft performs safely across its full designed operating envelope.

Test Pilot John Brodnicki stated in the release.

Progress toward FAA type certification

The environmental testing aligns with broader certification efforts for the Bell 525 program. According to reporting by Vertical Magazine, FAA pilots began test flights in the Relentless Advanced Systems Integration Lab (RASIL) in late July 2026.

The RASIL testing involves failure mode regression testing and final software evaluation. This phase is considered one of the final steps before the program moves into function and reliability testing.

Speaking at the Farnborough International Airshow in July 2026, Bell Senior Vice President of Strategic Pursuits Jeff Schloesser stated that the manufacturer has never been closer to achieving certification for the super-medium helicopter.

We view the completion of these cold weather and icing campaigns as a strong indicator of Bell’s confidence in the 525’s maturity. By conducting post-certification capability expansion tests concurrently with the final stages of FAA lab testing, Bell is positioning the aircraft for immediate operational utility upon entry into service. The reliance on the U.S. Army Redstone Test Center also highlights the value of cross-sector collaboration in navigating complex icing certification requirements, which remain one of the most challenging hurdles for new rotorcraft programs.
