Aircraft Accident/Incident Report

Caldwell, Idaho 83605
Thursday, June 19, 2014 20:49 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that he was flying his weight-shift control trike at low altitude when it struck power lines. Subsequently, the trike descended to the ground, which resulted in substantial damage to the structural tubing. The pilot further stated that his smoke colored visor attached to his helmet prevented him from clearly seeing the power lines. The pilot reported no preimpact mechanical failures or malfunctions with the aircraft that would have precluded normal operation.

NTSB Probable Cause Narrative

The pilot's failure to monitor the environment and to maintain sufficient altitude to clear power lines during low altitude flight.
