NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
Two witnesses observed the unregistered weight-shift control aircraft as it maneuvered. While maneuvering, the aircraft was "flying up to high altitudes and cutting the engine." The aircraft would glide to a lower altitude before restarting the engine and repeating the process. The aircraft also performed several steep bank turns at a "lower than normal" altitude. Just before the accident, one witness observed the aircraft "doing all sorts of crazy maneuvers." Moments later the aircraft began "spinning" or "corkscrewing" to the left, as descended vertically to the ground. The aircraft disappeared from view behind a tree line, but "at the last second" the engine briefly increased power, followed by silence. Examination of the accident scene revealed signatures consistent with a near-vertical descent and a postimpact fire. Examination of the wreckage revealed signatures consistent with overstress separation.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: A loss of control for undetermined reasons. Full narrative available
