Harbour Air signed a letter of intent to purchase 50 Magni650 electric engines from MagniX to convert its de Havilland DHC-2 Beaver aircraft to electric propulsion and the engine completed its first phase of testing at a NASA facility, AIN reported. The engine was tested as part of NASA’s Electrified Powertrain Flight Demonstration, which MagniX was awarded in 2021 as an EPFD partner. The NASA effort seeks to accelerate electric aviation into service. MagniX completed the preliminary design review on the engine in February, with more testing to occur in June with an expanded operating envelope for altitude, power and temperature.
