Bombardier has delayed the first flight of its CSeries aircraft until July.
The company has not committed to a specific date, though it has completed ground vibration tests, as well as software upgrades and corresponding tests for Flight Test Vehicle 1 (FTV1), the first CSeries aircraft. Transport Canada has also received the application for the FTV1 flight testing permit.
"In order to enhance the effectiveness of the flight program, Bombardier extended the timeline slightly to allow for additional software upgrades for improved system maturity and functionality," Bombardier said in a statement.
The CSeries is Bombardier's first full-size commercial aircraft family, with capacity for up to 149 passengers.
