ANC83FU003

According to a witness, the ultralight vehicle had just taken off, had turned to a downwind heading & was climbing, when it began to oscillate longitudinally. After a few oscillations, the vehicle nosed over, the wings folded & the ultralight crashed to the ground. All parts of the ultralight were accounted for & an exam revealed that the fractures were indicative of overload failures. Reportedly, the plt had only about 5 to 10 hrs in this make & model. According to the plt's friends, they had heard him talk about having to hold the nose down during flt. They stated he had a tendency to 'bury the airspeed' while flying. According to other plts that have flown this ultralight vehicle, the pterodactyl can achieve 55 KTS with only slightly over half throttle, it becomes increasingly pitch sensitive at high speeds & it requires excessive nose down pitch control above 55 KTS.
