Another Step Toward Certification With Up-Bending Main Wing
Structural Tests
Sino Swearingen
Aircraft Corporation took another step along the path in the FAA
certification process Wednesday by successfully completing the
critical up-bending ULTIMATE LOAD tests on the SJ30-2 main
wing.
Dr. Carl L. Chen, CEO and president of Sino Swearingen stated,
"This major milestone is one of the most important tests ever to be
conducted on a new aircraft and it is a giant leap in our
certification program to have passed the FAA Ultimate Loads
successfully and within our time schedule. Results validate the
critical structural strength of the main wing of this beautiful new
jet aircraft. Additional testing shows the wing and support
structures will provide customers with an amazing aircraft that has
low maintenance and high use of the aircraft under heavy load
conditions. The entire test team, led by John Vieger and Paul
Romano, has done an excellent job. We thank them and the FAA for
their excellent support."
"The test actually includes three ULTIMATE LOAD cases," said
John Vieger, Manager of Structure Analysis. The cases included wing
up-bending, fuselage down- bending and horizontal tail
down-bending. "And incredibly, everything is combined in one test.
In addition we connected 562 sensors to the aircraft and we were
taking readings from all sensors simultaneously throughout the
test. This is a great structural achievement for the SJ30-2
program."
