Sino Swearingen insists that the 2,500-nm-range SJ30-2 will be certified in the third quarter of this year, despite numerous program delays and the crash of S/N 002 in April 2003 (see page 1). “Three test aircraft–Serial Numbers 003, 004 and 005–are now flying seven days a week, and I’m comfortable that we will achieve FAA approval in the third quarter,” a company spokesman told AIN.

Last summer the company completed high-speed dive tests at Mach 0.90, confirming the SJ30-2’s Mach 0.83 high-speed cruise and that the aircraft does not encounter flutter at any operating speeds up to Mach 0.90. Since then, the spokesman said, the twinjet’s 91-knot stall speed has been validated–a feat accomplished thanks to the SJ30-2’s leading-edge slats and Fowler flaps.
