Beta Technologies’ Incremental Certification Strategy: Pioneering Electric Aircraft Propeller Approval

Beta Technologies has taken a significant step in the certification of electric aviation by securing the first-ever FAA Part 35 certification for a propeller designed specifically for electric propulsion systems. This milestone, achieved in collaboration with Hartzell Propeller, marks a pivotal moment in the maturation of the advanced air mobility (AAM) sector. The propeller, a five-blade carbon fiber design, was officially certified by the FAA on July 21, 2025, following four years of rigorous ground and flight testing.

This achievement is more than a technical success, it represents a validation of Beta’s stepwise certification strategy. By certifying individual components like the propeller before moving on to more complex systems such as the electric motor and full aircraft platforms, Beta aims to reduce risk, streamline regulatory processes, and accelerate time to market. This modular approach contrasts with more monolithic strategies employed by other eVTOL developers and is increasingly seen as a viable path forward in a rapidly evolving regulatory landscape.

Background: Beta Technologies and Hartzell Propeller

Founded in 2017 by engineer and pilot Kyle Clark, Beta Technologies has steadily emerged as a key player in the electric aviation sector. The company’s flagship aircraft, the ALIA series, includes both conventional take-off and landing (CTOL) and vertical take-off and landing (VTOL) variants. Beta’s mission revolves around building a complete ecosystem for electric aviation, encompassing aircraft, charging infrastructure, and operational logistics.

Hartzell Propeller, an Ohio-based company with over a century of experience in propeller design, has long been recognized for its innovation in propulsion systems. Known for supplying composite propellers for high-performance aircraft like the Boeing Condor, Hartzell brought deep domain expertise to the partnership with Beta. The collaboration began in 2021 and focused on developing a propeller optimized for the unique torque and load characteristics of electric motors.

The synergy between Beta’s forward-looking design philosophy and Hartzell’s technical rigor created a foundation for the successful certification journey. By leveraging Hartzell’s existing relationships with the FAA and its track record in composite propeller development, Beta was able to navigate the complex regulatory environment with greater efficiency.

The Stepwise Certification Strategy

Modular Approach to Risk Reduction

Beta’s certification strategy is built on the principle of modular validation. Rather than pursuing full aircraft certification from the outset, the company chose to certify individual components, starting with the propeller, followed by the electric motor, and then the aircraft platforms. This approach allows for focused testing, targeted risk mitigation, and iterative improvements without jeopardizing the entire program.

According to Beta CEO Kyle Clark, this strategy emerged from early flight testing experiences, which revealed challenges such as aerodynamic instability during transition phases and thermal management issues in battery systems. By isolating each component for certification, Beta could address these issues in a controlled manner, thereby improving overall system reliability.

Industry analysts note that this approach aligns well with the FAA’s evolving stance on certifying novel aircraft. The agency has increasingly advocated for data-driven, component-level validations as a means to accommodate rapidly advancing technologies. Beta’s stepwise model is seen as a practical implementation of this philosophy.

“Taking this huge problem… and chunking it down to the steps to get there”, Kyle Clark, CEO of Beta Technologies

FAA Certification of Hartzell’s Electric Propeller

On July 21, 2025, the FAA granted type certification under Part 35 to Hartzell’s five-blade carbon fiber propeller, marking it as the first such certification for an electric aircraft component. This milestone was the result of over four years of collaboration, during which the propeller underwent thousands of hours of testing under both ground and flight conditions.

The propeller was engineered to meet the unique demands of electric propulsion, including instantaneous torque delivery and regenerative braking. Tests included extreme scenarios such as ice ingestion, fatigue cycling, and regenerative load cases where the propeller acts as a windmill to recharge onboard batteries during descent.

This certification is a prerequisite for the next stages in Beta’s roadmap: FAA Part 33 certification of its 575hp electric motor (expected late 2025), followed by certification of the ALIA CX300 CTOL aircraft (2026–2027), and ultimately the ALIA A250 VTOL aircraft (targeted for late 2027).

Technical Specifications and Testing Protocols

The certified propeller features a ground-adjustable fixed-pitch design, tailored to handle the variable torque loads of electric motors. Its carbon fiber construction results in a 40% weight reduction compared to aluminum counterparts, and its aerodynamic profile limits noise to below 65 dB during cruise, an essential requirement for urban operations.

Testing protocols were extensive and included over 2,000 hours of fatigue testing under peak thrust conditions. Ice ingestion tests ensured structural integrity under instrument flight rules (IFR) conditions, while regenerative load testing validated the propeller’s ability to transition between propulsion and energy recovery modes.

These rigorous evaluations not only satisfied FAA certification requirements but also provided valuable data that can be leveraged in subsequent component and aircraft certifications, potentially reducing redundant testing by up to 30% according to industry estimates.

Broader Industry Context

Certification Challenges in the eVTOL Sector

The path to certifying electric vertical take-off and landing (eVTOL) aircraft is fraught with challenges. Traditional certification frameworks were designed for combustion-powered fixed-wing aircraft and helicopters, not for the hybrid characteristics of eVTOL platforms. As a result, developers must often work with regulators to create special conditions tailored to their specific technologies.

One major hurdle is the lack of FAA-approved flight simulators for eVTOL aircraft, which complicates pilot training and operational readiness. Additionally, vertically integrated manufacturers that design all components in-house face a more complex certification burden compared to those who partner with established suppliers.

Beta’s partnership model with Hartzell serves as a case study in how collaboration with certified suppliers can streamline the regulatory process. By leveraging Hartzell’s existing FAA certifications and compliance infrastructure, Beta reduced its documentation requirements and accelerated the certification timeline.

Global Regulatory Harmonization

Efforts are underway to harmonize certification standards across jurisdictions. The FAA and the European Union Aviation Safety Agency (EASA) issued a joint advisory circular in June 2024 to align their approaches to eVTOL certification. This includes graded compliance tiers based on aircraft size and use case, as well as a hybrid integration of airworthiness standards from Parts 23, 27, and 33.

These harmonized guidelines provide a framework that supports Beta’s stepwise approach. By enabling concurrent certification processes across U.S. and European facilities, the new standards reduce duplication and facilitate faster market entry. Beta has already capitalized on this by conducting demonstration flights across Europe during its 2025 Grand Tour.

The international alignment also opens the door for Beta to pursue global certification pathways, increasing its competitiveness in a market projected to reach over $100 billion by 2033.

Conclusion and Future Outlook

Beta Technologies’ successful certification of Hartzell’s electric propeller marks a turning point in the evolution of electric aviation. It validates a modular, stepwise approach to certification that not only aligns with regulatory expectations but also mitigates technical and financial risks. By focusing on component-level validation, Beta has created a replicable model for other developers navigating the complex landscape of eVTOL certification.

Looking ahead, Beta’s roadmap includes certification of its electric motor, CTOL aircraft, and eventually its VTOL platform. With strong financial backing and strategic industry partnerships, the company is well-positioned to lead the next phase of AAM development. As regulatory frameworks continue to evolve, Beta’s approach may serve as a blueprint for scalable, certifiable, and commercially viable electric aviation.

Japan Airlines Deploys Electric Aircraft Washing Robot at Narita

JAL will deploy the Aerowash AW3 robot at Tokyo Narita in 2026, cutting wash times 40% and water use 50%.

Published

on

Japan Airlines (JAL) will deploy a fully electric, remote-controlled aircraft washing robot at Tokyo Narita International Airport (NRT) later in 2026, a move projected to cut aircraft cleaning times by up to 40 percent and water consumption by half.

In a press release issued on August 28, 2026, the JAL Group announced the introduction of the Aerowash Remote-Controlled Aircraft Washing Robot (AW3), manufactured by Swedish firm Aerowash AB. The deployment marks the first time a domestic airline in Japan has implemented a program-controlled collaborative robot for aircraft exterior cleaning. The initiative aims to improve occupational health and safety for ground staff while reducing the environmental footprint of ground handling operations.

Operational efficiency and environmental impact

The AW3 is fully electric and battery-powered, eliminating direct exhaust emissions on the ramp during operation. According to the JAL Group, the automated system can reduce the time required to wash an aircraft by up to 40 percent compared to traditional manual methods. The robot is also expected to decrease water usage per aircraft by up to 50 percent.

Aviation Week reported that the AW3 system is compatible with several aircraft types in the Japan Airlines fleet, including the Boeing 737, Boeing 767, Boeing 787, and Airbus A350. Full-scale implementation at Narita is scheduled for late 2026 following comprehensive operational training for ground handling staff.

Labor strategy and Automation history

The aviation industry is increasingly turning to automated ground support equipment to mitigate labor shortages and improve turnaround times. Atsuki Kino of the Japan Airlines Airport Ground Handling Planning Department told The Straits Times that the primary objective is workload reduction rather than workforce elimination.

“The goal is not to reduce staff, but to reduce their workloads so they can use the time saved to perform other high-value tasks, changing the way they work,” Kino said.

The AW3 mitigates physical strain and chemical exposure for ground crews who previously conducted exterior washing manually. This is not the airline’s first attempt at automating exterior cleaning. According to Aviation Week, Japan Airlines tested a wired remote-controlled washing system in the 1990s. That initiative was ultimately abandoned due to technical limitations of the era, making the AW3 deployment a successful return to a concept first explored approximately 30 years ago.

AirPro News analysis

The introduction of the Aerowash AW3 by Japan Airlines highlights a broader industry shift toward electrifying and automating ground support equipment. As airlines face persistent global shortages in ground handling personnel, technologies that reduce physical fatigue and chemical exposure become critical retention tools. We expect to see similar collaborative robotics adopted across major Asian and European hubs over the next five years, particularly as Sustainability mandates force operators to scrutinize water consumption and ramp emissions. The 30-year gap between JAL’s initial wired prototype and the AW3 underscores how recent advancements in battery density and spatial programming were required to make automated aircraft washing commercially viable.
