Utah Completes First Hybrid-Electric Flight Under FAA eIPP

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.
