Diamond’s Williams FJ33-powered D-Jet didn’t fly as planned in October, but the first flight appears to be right around the corner. According to Diamond North American president Peter Mauer, the proof-of-concept D-Jet (S/N 001) is nearing completion at Diamond’s London, Ontario facility and will roll out next month. First flight is scheduled for late next month or early April, with Transport Canada and FAA certification expected late next year.

Mauer said the D-Jet interior has been changed to allow for wider rear seats. The flight-deck interior has been redistributed to allow for a three-screen–two 12-inch multifunction displays and one 15-inch primary flight display–Garmin G1000 avionics system. The company has also added an upgraded interior package to the options list.

The D-Jet’s split intake for its sole engine has been validated at Williams’ facility using a full-scale fuselage. Additionally, the company has completed wind-tunnel testing of a scale model.
