One of the two Grob SPn Utility Jets flying prototypes was destroyed during a “demonstration flight” near the company factory in Tussenhausen-Mattsies, Germany on Wednesday, Grob CEO Niall Olver confirmed to AvWeb.
Chief SPn test pilot Gerard Guillaumaud, 45, the sole occupant aboard the aircraft, was killed. Guillaumaud was a former French Air Force pilot and a graduate of the National Test Pilot School in Mojave, Calif. The crash occurred at 1:20 p.m. local time shortly after takeoff, according to witnesses. Guillaumaud was demonstrating the aircraft’s flight performance to a group of invited company guests on the ground.
