The spn test aircraft No. 3 (D-CSPJ) successfully completed its first two flights, 29 October 2007. The aircraft took off at 9:28 am local time from the company’s airfield at Tussenhausen-Mattsies, Germany, where it is being developed and built.
The flight testing included basic systems checkouts, stability and control evaluation and a first landing at the Allgäu Airport in Memmingen as planned. The aircraft returned to the company’s airfield after the second flight. Total flying time was 1 hour and 26 minutes. At the controls were Chief Test Pilot Tore Reimers and Test Pilot Peter Weger. Test aircraft No. 3 is flying most of the systems that will be installed in the fully conforming series production aircraft.
First flight of test aircraft No. 3 was accomplished following an intensive period of comprehensive ground testing of systems such as fuel, engines, hydraulics, landing gear and avionics. Niall Olver, Chief Executive of Grob Aerospace has confirmed the company’s commitment to add a further three aircraft to support the flight test program. Production of the fourth test aircraft is already well under way, scheduled to join the program in Q4 2007. In due course this will be followed by the first two series production aircraft, both of which will join the program for functional reliability testing, and featuring the full interior designed by Porsche Design Studio.
