Ampaire Inc has announced that the Federal Aviation Administration (FAA) has approved the G-1 Issue Paper for its AMP-H570 hybrid electric propulsion system.
“This approval establishes the airworthiness and environmental standards required for FAA Supplemental Type Certification, marking a significant milestone toward commercial deployment of Ampaire’s hybrid electric solutions,” said the company in a press release. “The FAA’s G-1 Issue Paper defines the regulatory framework that the AMP-H570 must satisfy to achieve Supplemental Type Certification (STC). With this approval, Ampaire advances to the next phase: working with the FAA to finalize the Means of Compliance and complete the testing campaign to validate the technology.
“The AMP-H570’s hybrid architecture – similar in principle to early automotive hybrids – enables inflight recharging and does not require ground charging infrastructure. Combined with its retrofitready design, the system offers a plug-and-play solution for operators, reducing both deployment time and upfront costs while accelerating the path to lower-emission aviation.”
According to the company the the AMP-H570 delivers economic benefits for regional airlines and cargo operators, including lower fuel consumption, reduced maintenance costs, and extended aircraft service life. “This positions Ampaire as a commercially scalable, cost-effective solution for cleaner aviation. The system also supports compliance with tightening global emissions regulations – enabling operators to reduce carbon footprint without sacrificing operational performance or profitability.”
Ampaire’s Eco Caravan, equipped with the AMP-H570, has already demonstrated more than double the fuel efficiency of conventional aircraft during flight tests, says the company. Recent ground tests successfully ran the system on 100 percent sustainable aviation fuel (SAF). The US Air Force has funded a research program to apply the AMP-H570 into the King Air, and other aircraft manufacturers have begun exploring both Integrated Parallel Hybrid and Series Hybrid applications of the AMP-H570 into new aircraft designs.
“The FAA’s issuance of the G-1 Certification Basis for the AMP-H570 is a major step forward in commercializing hybrid electric propulsion,” said Kevin Noertker, Cofounder and CEO of Ampaire. “This milestone demonstrates that we are executing on our regulatory roadmap, removing risk for investors and customers, and accelerating real-world deployment.”
