Bye Aerospace’s All-Electric eFlyer 2 Fuselage Assembly Contract Work Begins

George E. Bye, CEO of Bye Aerospace, said the company has contracted with Composites Universal Group (CUG) to begin assembly of the production eFlyer 2 fuselage, the first major component being assembled.

 “We continue to make advances in the certification process,” Bye said. “These activities commence production of the first conforming eFlyer 2, the first of three planned conforming eFlyer 2 aircraft that will be used to help complete final FAA certification. We look forward to working with Steve Ruege and the team at CUG.”

 “Composites Universal Group is extremely proud to have been selected by George and the team at Bye Aerospace to begin tooling and construction for the all-carbon fiber fuselage for Serial #001 of the eFlyer 2 aircraft,” said Steve Ruege, CEO of CUG. “We all feel here at CUG that Bye Aerospace has absolutely hit a home run with this next-generation all-electric aircraft design. We are very excited about working collaboratively with the Bye Aerospace team to achieve FAA certification and commencing production.”

Bye Aerospace’s current and future families of aircraft feature engineering, research and electric aircraft solutions designed to specifically address compelling market needs.  Benefits include five-fold lower operating costs, no CO2 emissions, and decreased noise. Bye Aerospace estimates the eFlyer will eventually eliminate the release of millions of metric tons of CO2 each year as its deliveries begin and the general aviation fleet is replaced.
