Probable cause
The pilot’s failure to maintain aircraft control while maneuvering near power lines.
NTSB analysis
A witness located near the accident site reported observing the weight-shift-control trike flying around the area at a low altitude before hearing the engine power increase and seeing the trike ascend to avoid striking trees. The witness observed the trike continue to maneuver around the area and conduct a series of turns before he lost sight of the trike. Another witness reported seeing the trike approach two sets of power lines and then suddenly bank sharply left and descend into the ground. Postaccident examination of the recovered trike revealed no evidence of any preexisting mechanical anomalies that would have precluded normal operation.
