San Antonio, TX, USA – Sino Swearingen Aircraft Corp. (SSAC) announced today that the FAA recently issued a Type Inspection Authorization (TIA) for the new SJ30 executive business jet, that included Minimum unstick VR abuse testing.

Incredible takeoff photo of SJ30 during radical attempts of pilots to demonstrate abused Vr takeoffs, tail strikes and stall attempts. All tests were completed safely and demonstrated that the SJ30 can take off while maintaining extreme pitch attitudes and no tail strike or stall.

Company minimum unstick speed (VMU) testing was recently completed during a series of flight tests in which the test pilots purposely abused the normal takeoff procedures by testing for tail strike or stall capabilities at Vr. The new SJ30 successfully demonstrated that it can safely takeoff and fly away from ground effects while maintaining extreme pitch attitudes without any occurrence of a tail strike or stall.

Pitch attitudes at takeoff were at extreme positions of up to 15 degrees nose up. The tests open the way to unrestricted rotation speed Vr that will provide low and easy takeoff speeds V2 and shorter takeoff distances. This assists in the projected easy and very good handling takeoffs with the new SJ30 twinjet aircraft.
Sino Swearingen Aircraft Corporation is certifying the new SJ30 in San Antonio TX with 430 employees in four facilities totaling over 220,000 sq ft in the USA Coast To Coast. The Company continues spectacular acceleration of the FAA certification projected to be final in the second half of this year 2005. The new Sino Swearingen SJ30 business jet is a high performance, long range, intercontinental, twinjet aircraft with an incredible 2,875 sm range and one of the highest cruise speeds in the industry to Mach .83 (560 mph). The SJ30 will operate at altitudes to 49,000 feet and maintain a “Sea Level Cabin” to 41,000 ft with the best pressurization in the business jet world, 12 psi. The new SJ30 will also have certification for single pilot operations. Sino Swearingen Aircraft Corporation business plan is aggressively geared to become the world’s leading aircraft producer by creating a family of cost-efficient, high performance, high-quality, superior technology, business jets. Specifications are preliminary and subject to change.
