Merlin Achieves SOI 2 Milestone with New Zealand Aviation Authority
Merlin progresses in certifying its AI autonomous flight system by reaching SOI 2 with New Zealand’s aviation authority, advancing global approval.
Merlin’s Autonomous Flight Tech Clears Major Hurdle on Path to Certification
In the world of aviation, safety and reliability are paramount. The process of introducing new technology, especially something as groundbreaking as artificial intelligence-powered autonomous flight, is rightly subjected to intense scrutiny. This is the world Boston-based Merlin operates in, developing autonomous flight technology for both commercial and military aircraft. The company’s flagship product, the Merlin Pilot, is an AI-driven system designed to handle an aircraft from takeoff to touchdown. This isn’t just a far-off concept; it’s a technology actively moving through the rigorous certification process required to make it a reality in our skies.
Recently, Merlin announced a significant step forward in this journey. The company has achieved Stage of Involvement (SOI) 2 with the Civil Aviation Authority of New Zealand (CAA NZ). This milestone is part of a meticulous, multi-stage audit process known as DO-178, which is the global standard for certifying airborne software. Reaching SOI 2 signifies that the regulators are deeply engaged in reviewing the software’s development, providing a critical vote of confidence in Merlin’s approach. This isn’t just a procedural checkbox; it’s a clear signal that the path to certifying AI in aviation is becoming more defined.
The significance of this achievement extends beyond Merlin itself. As the aviation industry grapples with pilot shortages and looks for ways to enhance safety and efficiency, autonomous systems are seen as a key part of the future. Merlin’s progress with regulators in New Zealand, which is being conducted in parallel with the U.S. Federal Aviation Administration (FAA), could help establish a clear and trusted framework for certifying these advanced systems globally. It’s a methodical, step-by-step process designed to build trust and ensure that the future of flight is as safe as its past.
The Nitty-Gritty of Certification: What is SOI 2?
The certification of flight-critical software is a marathon, not a sprint. The DO-178 standard is broken down into several Stages of Involvement, or SOIs, to allow regulators to oversee the development process from start to finish. Merlin’s journey began with achieving SOI 1 in May 2023, which involved the CAA NZ’s acceptance of the company’s detailed planning documents. This initial stage is all about laying the groundwork, defining how the software will be designed, built, and tested to meet the highest safety standards.
Achieving SOI 2 is a much more substantial milestone. At this stage, approximately half of the software data for the Flight Control Computer (FCC) has been formally reviewed by the regulatory body. This means the CAA NZ has moved beyond reviewing plans and is now examining the actual execution of those plans. They are looking at the code, the tests, and the documentation to ensure everything aligns with the agreed-upon safety-critical standards. It’s a demonstration of transparency and proves that Merlin is adhering to the disciplined engineering practices required for such a critical system.
This concurrent validation with the FAA is also a crucial part of the strategy. Under the Bilateral Aviation Safety Agreement between the U.S. and New Zealand, the progress made with the CAA NZ directly informs the FAA’s own certification process. This dual-track approach is efficient and suggests a clear pathway to market in two key aviation jurisdictions. The aircraft at the center of this certification program is Merlin’s Cessna Grand Caravan 208B, a versatile and widely used aircraft, making the potential impact of this Supplemental Type Certificate (STC) significant.
“SOI 2 reflects the disciplined engineering and certification practices our team has put in place. Each stage of this process deepens regulator confidence, reduces program risk, and advances the Merlin Pilot toward certification and real-world operations.”

Building Momentum: Military Contracts and Public Offerings
While the civil certification process is a major focus, Merlin has also been making significant inroads in the defense sector. The company has secured over $100 million in contracts from military customers, a testament to the robustness and potential of its autonomous flight technology. These partnerships, including one with industry giant Northrop Grumman, allow Merlin to develop and refine its systems in demanding, real-world environments. This dual-use strategy is smart, as advancements in the defense sector often pave the way for innovations in civil aviation.
Further signaling its growth trajectory, Merlin recently announced its intention to go public. The company plans to merge with Inflection Point Acquisition Corp. IV, a special purpose acquisition company (SPAC). This move is designed to provide the capital necessary to scale its operations, continue its research and development, and push the Merlin Pilot through the final stages of certification and into commercial service. Going public is a significant step for any company, and for Merlin, it reflects a strong belief in its technology and its market potential.
The company is also expanding its physical footprint and operational capabilities. Merlin has established Hanscom Field in Massachusetts as its new flight test center, with operations slated to begin in early 2027. This facility will be crucial for the flight test campaign of its certification-ready Cessna Caravan. Additionally, a Cooperative Research and Development Agreement (CRADA) with the United States Air Force (USAF) aims to advance autonomous capabilities to improve mission resilience in contested environments. These developments paint a picture of a company that is not just focused on a single milestone but is building a comprehensive ecosystem to support its long-term vision.
The Broader Skies: Implications for the Future of Aviation
Merlin’s steady progress is more than just a corporate success story; it’s a bellwether for the entire aviation industry. The successful collaboration between a technology developer and a civil aviation authority on a system as complex as an AI-powered pilot sets a valuable precedent. It demonstrates that a pathway exists for the safe integration of autonomy into the national airspace. As regulators become more familiar and comfortable with these systems through processes like the SOI audits, the door opens for wider adoption.
The potential benefits of this technology are vast. For the cargo and logistics industry, autonomous flight could lead to more efficient and cost-effective operations. In passenger transport, it could enhance safety by reducing human error and assisting pilots in complex situations. Furthermore, as the industry faces a global pilot shortage, autonomous systems could help bridge the gap, ensuring that air travel remains a reliable and accessible mode of transportation. The journey is long, and there are still hurdles to overcome, but milestones like Merlin’s SOI 2 achievement are critical steps in the right direction, moving autonomous flight from the realm of science fiction to a tangible reality.

Utah Completes First Hybrid-Electric Flight Under FAA eIPP
UDOT and Ampaire flew the hybrid-electric EEL from Salt Lake City to Cedar City on August 6, 2026, launching the uFLY program.
On August 6, 2026, the Utah Department of Transportation (UDOT) and Ampaire Inc. conducted the first hybrid-electric aircraft demonstration flight in Utah, officially launching a multi-state initiative to integrate advanced air mobility technologies into the National Airspace System (NAS).
The flight, which traveled between Salt Lake City International Airport (SLC) and Cedar City Regional Airport (CDC), serves as a major milestone in the Federal Aviation Administration (FAA) Electric Vertical Takeoff and Landing Integration Pilot Program (eIPP). According to press releases from UDOT and the FAA, the demonstration provides real-world operational data to evaluate emerging aviation technologies without requiring new airport infrastructure.
The uFLY initiative and FAA integration
The August 6 flight marks the operational debut of UDOT’s uFLY program. The initiative is a public-private partnership coordinating with Oregon, Idaho, Arizona, and Oklahoma to serve as a proving ground for regional aviation technologies across five western states. The FAA and the U.S. Department of Transportation (USDOT) selected Utah as one of eight nationwide eIPP participants on March 10, 2026, initiating a three-year effort to test advanced aircraft in real-world conditions.
FAA Deputy Administrator Chris Rocheleau stated that the demonstration will yield valuable operational experience to help regulators understand how to safely integrate Advanced Air Mobility (AAM) into the NAS. The data collected during these flights is intended to inform future regulatory frameworks for hybrid and electric propulsion systems.
UDOT Commissioner Carlos Braceras noted that the data collected will allow the FAA to evaluate technologies capable of strengthening regional connectivity and expanding economic opportunity. UDOT Aeronautics Director Matt Maass added that the demonstrations help authorities understand how these technologies can safely connect communities.
Aircraft technology and flight operations
The demonstration utilized the Ampaire EEL, a modified Cessna 337 Skymaster serving as a hybrid-electric testbed. The aircraft is equipped with the AMP-H570 hybrid-electric propulsion system, which features an electric motor driving the nose propeller and a conventional combustion engine powering the aft propeller. The battery technology powering the electric propulsion was developed by EP Systems, a manufacturer based in Utah.
Ampaire test pilot Zack Kraus reported that the dual-propulsion configuration proved advantageous during the flight profile.
“Over Utah’s mountainous terrain and high-density-altitude conditions, the additional electric boost power helped us climb through conditions that would have been much more limiting in a conventional-engine-only configuration,” Kraus said.
Ampaire has accumulated 35,000 flight miles across its hybrid-electric fleet to date. Following initial deployment flights between California and Utah in July 2026, Ampaire and its uFLY partners plan to introduce the Eco Caravan, a hybrid-electric upgrade for the Cessna Grand Caravan, in subsequent phases of the program to test commercial viability.
Ampaire Inc. Co-founder and CEO Kevin Noertker emphasized the immediate applicability of the technology for regional operators.
“This mission demonstrates why hybrid-electric aviation is practical for regional operations today. Our hybrids operate across meaningful distances, varied terrain and existing airports without waiting for new infrastructure. The propulsion system changes; the regional aviation system does not have to,” Noertker said.
AirPro News analysis
We view the uFLY demonstration as a pragmatic step in the broader AAM transition. While much of the industry focus remains on fully electric vertical takeoff and landing (eVTOL) aircraft, hybrid-electric fixed-wing platforms like the Ampaire EEL offer an immediate pathway to lower emissions using existing airport infrastructure. By leveraging conventional airframes like the Cessna 337 Skymaster and the Cessna Grand Caravan, operators can bypass the lengthy certification hurdles associated with clean-sheet aircraft designs. The FAA’s involvement through the eIPP indicates a regulatory willingness to gather empirical data on hybrid operations, which will be critical for establishing certification standards and operational procedures for future AAM platforms.
