All major milestones with the Sovereign have been completed on or ahead of schedule, according to Brad Thress, Sovereign senior product director, who added that Cessna displayed the super-midsize jet, with completed interior, for the first time at the NBAA Convention last month. So far two test airplanes (a prototype and S/N 001) have logged 220 hr on some 120 flights. The prototype first flew in February, while S/N 001 made its maiden flight in June.
Milestones recently completed include FAA and CAA certification of the model’s Pratt & Whitney Canada PW306C engines; completion of three lifetimes of cyclic fatigue testing (36,000 cycles); stall development and stability control work; and engine installation on S/N 002, scheduled to join the flight-test program this fall. The $12.695 million Sovereign is expected to receive FAA certification late next year. Customer deliveries are to begin in early 2004.
