MT-Propeller Earns FAA STC for Piper PA-28 Composite Propeller
MT-Propeller receives FAA STC SA04463NY for its MTV-9-B/198-52 propeller on Piper PA-28-235 and PA-28-236 aircraft.

MT-Propeller Entwicklung GmbH has secured Federal Aviation Administration (FAA) Supplemental Type Certificate (STC) SA04463NY, authorizing the installation of its three-blade natural composite propeller on Piper PA-28-235 Cherokee Pathfinder and PA-28-236 Dakota aircraft. The certification, issued on June 2, 2026, allows operators to upgrade to the MTV-9-B/198-52 propeller system for measurable gains in climb and cruise performance.
Announced in a company press release in June 2026, the FAA approval follows the European Union Aviation Safety Agency (EASA) STC 10062339 R1, which was granted for the same installation on August 15, 2025. The upgrade applies specifically to airframes powered by Lycoming O-540-B1B5 or O-540-B4B5 engines.
Performance and design specifications
According to MT-Propeller Vice President Martin Albrecht, the three-blade installation delivers an approximate 5 percent enhancement in climb performance under Maximum Takeoff Weight (MTOW), Sea Level, and International Standard Atmosphere (ISA) conditions. Cruise speeds also see an increase of two to three knots at MTOW and ISA conditions.
The MTV-9-B/198-52 features natural composite blades designed for vibration damping, resulting in nearly vibration-free operation. The manufacturer notes the blades have no life limitation and are repairable following foreign object debris (FOD) damage. Additionally, the blades incorporate bonded stainless steel leading edges to provide erosion protection. The installation also yields significant reductions in both internal and external noise levels.
Corporate expansion and market footprint
The recent FAA certification adds to MT-Propeller’s portfolio of more than 230 STCs worldwide, with over 34,500 of the company’s systems currently in service. The German manufacturer has been actively expanding its operational footprint to support this growing market presence.
In April 2026, the company established MT-Propeller Canada Inc., a joint venture with AMK Aviation Inc. based in Murillo, Ontario, aimed at improving sales and field support for North-American operators. Concurrently, MT-Propeller expanded its headquarters in Atting, Germany, opening three new production facilities totaling approximately 8,000 square meters (86,000 square feet) to increase manufacturing and service capacity.
AirPro News analysis
The continued rollout of composite propeller STCs for legacy general aviation airframes like the Piper PA-28 series highlights a sustained market demand for modernization. For operators of older aircraft, upgrading to a modern three-blade composite system often represents a cost-effective method to extract better performance and reduce cabin fatigue without the expense of a full engine upgrade or airframe replacement. We view MT-Propeller’s concurrent expansion of its North American support network as a necessary step to sustain its aggressive STC development strategy in the United States and Canada.

Neptune Aviation Takes Delivery of First Airbus A319 Airtanker
Neptune Aviation Services receives its first A319 in Alabama, beginning an 18-month conversion for wildland firefighting deployment in 2028.

Neptune Aviation Services has taken delivery of its first Airbus A319 at Commercial Jet’s maintenance facility in Dothan, Alabama, marking the start of an 18-month conversion process to transform the commercial airliner into a next-generation wildland firefighting airtanker.
Announced in a press release on June 24, 2026, the delivery initiates a fleet transition for the Missoula, Montana-based operator. Neptune plans to replace its current fleet of BAe 146 aircraft with the A319, aiming for initial operational deployment during the 2028 wildfire season.
Transitioning to the Airbus A319 platform
The selection of the Airbus A319 follows a two-year evaluation period by Neptune to identify a successor to the BAe 146. The new platform will increase the operator’s minimum retardant capacity to 4,500 gallons, a significant upgrade from the 3,000-gallon maximum capacity of the BAe 146. The A319 will also provide increased fuel load and higher cruise speeds, enabling faster response times and extended duration over active fire zones.
Engineering and design work is already underway. Neptune recently completed the Critical Design Review for the conversion in partnership with Aerotec & Concept, a France-based engineering firm. With major design decisions finalized, engineers are currently developing the manufacturing drawings required for the structural modifications.
“The arrival of our first A319 culminates years of planning within Neptune and collaboration with valued partners to ensure we remain at the forefront of aerial firefighting,” stated Jennifer Draughon, President of Neptune Aviation Services. “As wildfire threats grow in size and complexity, we are investing in the next generation of airtankers to continue to deliver the capabilities expected by our agency partners and the communities we protect.”
Conversion timeline and testing phases
The physical conversion of the aircraft will take place at Commercial Jet’s 400,000-square-foot maintenance facility in Alabama. The modification process is expected to take 18 months, placing completion in late 2027 or early 2028.
Before heavy modifications begin, Neptune plans to conduct initial test flights of the unmodified A319 in the coming weeks. These flights will establish baseline performance metrics that will inform the subsequent engineering work.
Nic Lynn, Vice President of Operations for Neptune Aviation Services, emphasized the importance of having the physical airframe on hand to advance the program.
“The acquisition of our first A319 is a pivotal moment for our organization and the wildland firefighting industry,” Lynn said. “The upgrade of our airtanker fleet is fully underway. We have a physical aircraft available that we can convert for aerial firefighting. Our team can start performing test flights, and we can start zeroing in on completing the modifications that must be made to have the aircraft ready for 2028.”
AirPro News analysis
We view Neptune’s transition to the Airbus A319 as a logical progression in the aerial firefighting sector, which has increasingly relied on converted narrowbody commercial aircraft to meet the demands of longer and more intense fire seasons. The BAe 146 has served operators well due to its short-field performance and four-engine redundancy, but aging airframes and limited payload capacities necessitate modernization. By adopting the A319, Neptune secures a platform with a robust global supply chain, widespread parts availability, and modern avionics, which should translate to higher dispatch reliability when fire activity peaks.

“As demand for advanced aerospace engines continues to grow, this expanded capacity enables ATI to deliver high-quality products with increased throughput and the differentiated performance our customers need. ATI is improving supply chain resilience to support industry growth,” Fields said.
Capital investments and recent strategic agreements
Funding for the new Mexican facility is accounted for within ATI’s existing capital expenditure guidance. The operational launch follows a series of financial and strategic moves by the company earlier in the month.
On June 3, 2026, ATI priced a $450 million public offering of 5.875% Senior Notes due in 2033. Shortly after, on June 11, 2026, the company secured a long-term strategic material supply agreement with BWX Technologies to support the US Naval Nuclear Propulsion Program through fiscal year 2030.
AirPro News analysis
Aerospace engine supply chains remain one of the most significant choke points for commercial aircraft production. Engine manufacturers face persistent delays in sourcing forged components, which require rigorous nondestructive testing and precision machining before they can be integrated into a powerplant. We view ATI’s decision to consolidate these post-forging steps in a single facility as a practical measure to eliminate logistical handoffs. By reducing the physical distance parts must travel between forging and final inspection, suppliers can incrementally improve throughput and help original equipment manufacturers meet their delivery targets.

Vallair Gains A330neo Base Maintenance Approval in France
Vallair receives regulatory approval for A330-800 and A330-900 base maintenance at its Châteauroux facility in France.

Aviation asset lifecycle and MRO provider Vallair has secured regulatory approval to perform base maintenance on the Airbus A330neo family at its facility in Châteauroux, France. The certification positions the company to capture growing widebody maintenance demand as operators extend the service life of existing fleets amid global supply chain constraints.
In a press release issued on June 23, 2026, Vallair confirmed the approval covers both the Airbus A330-800 and Airbus A330-900 variants. The authorization allows the company to conduct scheduled heavy maintenance checks, structural inspections, and modifications for the re-engined widebody type.
Expanding widebody capabilities at Châteauroux
The Châteauroux site features an 8,500-square-meter hangar dedicated to Airbus aircraft support. The facility can simultaneously accommodate up to five Airbus A321 size aircraft, or a mixed configuration of A330s and A321s.
Grégoire Lebigot, President and CEO of Vallair Group, stated the approval reflects the company’s investment in technical expertise, training, and infrastructure.
“The addition of A330neo capability broadens Vallair’s service portfolio and creates new opportunities to support existing customers while attracting operators seeking approved maintenance capacity for the aircraft type,” Lebigot said.
Strategic positioning in the MRO super cycle
Vallair already holds maintenance certifications for the Airbus A330ceo and Airbus A340 families. According to reporting by AeroMorning, the addition of the A330neo serves as a stepping stone for potential future certification on the Airbus A350.
The aviation maintenance sector is currently navigating an extended super cycle, as noted by industry data platform ePlaneAI. This cycle is characterized by heightened demand for heavy checks and technical services, driven largely by delays in new aircraft deliveries that force airlines to operate older airframes longer than initially planned.
AirPro News analysis
We view Vallair’s A330neo certification as a timely strategic move that capitalizes on current aerospace supply-chain bottlenecks. With original equipment manufacturers struggling to meet delivery targets for new widebody aircraft, airlines are retaining current-generation and newly delivered A330neos for intensive utilization. The specific regulatory body granting the approval was not named in Vallair’s announcement, but securing base maintenance rights in Europe provides a critical relief valve for operators facing constrained MRO slot availability globally. If Vallair successfully leverages this capability into an eventual A350 approval, the Châteauroux facility will become a highly competitive independent node for Airbus widebody operators.
