One of the very early production Dash 7s (S/N 11), delivered new to Wardair in June 1979. This one spent most of its later years with Trans Capital Air operating flights for the United Nations in Europe and the Middle East/Africa. It was purchased by Air Tindi in 2021 and exported to the US this year. From what I can understand, Air Tindi, NASA, magniX and AeroTEC will be using the aircraft as part of the "Electrified Powertrain Flight Demonstration Project" to develop and test hybrid electric aircraft engines.
