The nine-passenger eCaravan plane is the result of a collaboration between engine company magniX and aerospace firm AeroTEC, according to a press release from magniX.
The aircraft uses electric propulsion systems manufactured by magniX.

The aircraft, an adapted Cessna Caravan 208B, will make its first flight on May 28 at an airstrip in Washington State at 8 a.m. local time (11 a.m. ET).
The original Cessna Caravan is one of the most widely used middle-mile planes in the world, with more than 2,600 aircraft working in 100 countries, the press release states.
The all-electric version will use a 750-horsepower (560kW) magni500 propulsion system.
“As the world’s largest all-electric aircraft, this first flight is a significant milestone in disrupting the transportation industry and accelerating the electric aviation revolution,” reads the press release.
It goes on, “magniX’s ultimate goal is to better connect communities by bringing to market an advanced all-electric propulsion system that offers lower cost of operations and zero emissions.”
The company also provided propulsion systems for a six-seater all-electric plane flown for the first time in October.
Operator Harbour Air called the flight a “world first” for the aviation industry after the plane flew for about 15 minutes after taking off from Vancouver, Canada.
At the time, magniX CEO Roei Ganzarski said in a statement that the transportation sector — and the aviation industry in particular — is “ripe for a massive disruption.”
Ganzarski added that the flight proved that “low-cost, environmentally friendly, commercial electric air travel” could be possible in the “very near future.”
All-electric powered aircraft are also being developed elsewhere in the world, including in the UK.
Cranfield Aerospace Solutions (CAeS) in England announced in November that it is working on electric planes, estimating that commercial flights might start as early as 2023.
