Grob Business Jet Prototype Returns to Flight Test

March 5, 2007, 9:19 AM

Grob Aerospace has restarted the flight-test program for its SPn jet, just short of three months after the crash of its second prototype on November 29. The first SPn prototype took to the air again on February 23 from the company’s headquarters at Tussenhausen-Mattsies, Germany. Germany’s Federal Office of Civil Aviation approved the resumption of flight trials after Grob completed a 300-hour maintenance check and a thorough inspection of the aircraft. The second prototype will focus on systems and performance evaluations. A third prototype is due to start flying in the spring. Grob is building another SPn fuselage to be used for dynamic fatigue tests. The manufacturer plans to complete EASA certification in the first quarter of next year, followed by FAA certification in the second quarter of next year. “Having the SPn flying again reconfirms to the industry that we are still confident on the road to certification,” said Grob Aerospace CEO Niall Olver.
