Certification Due the Second Half of This Year

Sino Swearingen Aircraft Corporation (SSAC) announced Monday that it has successfully completed water ingestion high speed testing of the new SJ30-2 twinjet aircraft. The company tested the aircraft for drenched and flooded runway conditions for both rain and slush.

"We are ecstatic about this amazing test as it shows the superb functionality and strength of the "trailing link" landing gear and it's excellent operation under the harshest conditions," said Dr. Carl Chen, CEO and President of SSAC. "The entire company is excited as this test emphasizes some of our final tests to FAA certify the new SJ30-2 by the second half of this year."

"The accomplishments and extra team efforts provided by the employees at SSAC and the FAA are significant in obtaining the certification on time and are greatly appreciated by our customers and the entire management team at SSAC," added Chen.

The intensive testing included a number of very high-speed runs of the aircraft through water troughs with levels of water up to three quarters of an inch deep. The maximum water depth was set to include the requirements for both the FAA and EASA JAA, testing under rain drenched, slush, and flooded runway conditions.

The speed of the SJ30-2 as it entered the water troughs was as high as 126 mph. The main landing gear and nose landing gear were all put through their paces numerous times in this spectacular test. The purpose of the test is to simulate a flooded runway with rain and slush and to verify that no tendency exists for unapproved amounts of water to enter the engine inlets during landing, take off, and runway operations.

The SJ30-2 twin engine business jet completed this testing without needing modifications to the aircraft design.

The trailing link landing gear system is similar to an airliner design as it uses two wheels on each main landing gear and two wheels on the nose gear for a total of six wheels and tires on the aircraft. This combination of dual wheels all around and trailing link landing gear provides smooth taxi, takeoff and landing characteristics and braking efficiency. Of course, it also adds dual wheel safety protection for the aircraft in case of a tire loss.
