    SAN ANTONIO, March 6 /PRNewswire/ -- Sino Swearingen Aircraft Corporation
 (SSAC) announced today the completion of another major milestone for the SJ30
 business jet.  The final flight test in actual icing conditions was completed
 on March 1, 2006 in Provo, Utah.  This testing consisted of the FAA
 requirement to complete a 45-minute hold in actual maximum continuous icing
 conditions, and was completed by Test Pilots Mark Fairchild, John Siemens, and
 Flight Test Engineer Schuyler Horn.

     On October 27th, 2005, the company announced that it had received FAA Type
 Certification for the SJ30, and that two tests remained before the initial
 delivery to a customer.  The two remaining tests were for the approval for
 flight into known icing and the approval of the aircraft's interior.
     DER Test Pilot John Siemens said "The airplane performed remarkably well
 in the extreme icing conditions we encountered.  It is also my opinion that
 the SJ30 performed better in the ice than any other airplane I have previously
 certified for flight in known icing conditions."
     The SJ30 is equipped with electrically heated windshields and uses engine
 bleed air heat to anti-ice the wings and engines.  Pneumatic boots are used to
 de-ice the horizontal tail.  The approval flight involved 50 minutes of
 maximum continuous icing conditions and more than another hour of intermittent
 icing conditions, which resulted in a build up of over 4 inches of ice on
 unprotected areas of the aircraft.  Siemens noted, "The flight characteristics
 and handling qualities were very good with this residual ice accumulation.  In
 the post flight debriefing, the flight test crew all agreed that the SJ30 is
 one of the safest airplanes on the market today when it comes to flying in
 icing conditions."
     Earlier in February, test pilot John Siemens and other members of the
 flight test crew completed artificial ice shapes testing at Roswell, NM.  This
 testing is required to demonstrate aircraft handling characteristics,
 including stability, control, and stall characteristics, with simulated ice
 attached to the airframe, replicating what would accumulate on unprotected
 surfaces during flight in a 45-minute maximum continuous ice encounter.
     SSAC's SJ30 business jet is a high performance jet aircraft with a range
 of over 2,500 nautical miles (2,875 statute miles) and the highest cruise
 speed in the light jet industry of Mach .83 (486 knots or 560 mph).  This
 single pilot certified jet operates at altitudes to 49,000 feet and can
 maintain a sea level cabin at an aircraft altitude of 41,000 feet, made
 possible by the use of industry leading 12 psi cabin pressurization system.
 SSAC is positioned to produce a family of cost efficient, high performance,
 high quality business jets.  Additional information, updates, 360 virtual tour
 views, photos and specifications are available at .
