Ampaire Scores FAA G-1 for Hybrid-electric Propulsion System
FAA approves first G-1 certification basis for a hybrid-electric aircraft powertrain
Eco Caravan
Ampaire claims the hybrid-electric, retrofit-ready AMP-H570 aircraft propulsion system can deliver up to a 70% reduction in fuel burn and emissions, along with 40% lower operating costs, compared with the standard Cessna 208B Grand Caravan.

The FAA has approved the certification basis for Ampaire’s hybrid-electric aircraft propulsion system, a retrofit-ready powertrain that could enter service in 2026 on the Eco Caravan, a modified Cessna 208B Grand Caravan.

According to Ampaire, its AMP-H570 propulsion system is the first hybrid powertrain to earn an FAA G-1 issue paper, which identifies the regulations and airworthiness standards for certification. The Long Beach, California-based company expects to obtain supplemental type certificates (STCs) for the AMP-H570 and the Eco Caravan by the end of 2026, followed by additional STCs for other aircraft types in the future.
