Analysis
The plt & his instructor were departing the airport in separate ultralight vehicles to proceed on a x-country flt for a fly-in. The instructor saw the plt takeoff, but lost sight of him moments later & did not see the accident. However, an eye witness stated that he saw the ultralight flying from the airport, in a right turn. The witness heard the eng rev up & saw the nose of the vehicle drop. He reported that the ultralight entered a steep spiral & impacted the ground. An on-scene investigation revealed no evidence of a preimpact descrepancy with either the eng or the airframe.
