The NTSB's narrative final · quoted from the NTSB record
The pilot and passenger were on a personal flight in the weight-shift-control trike and had just completed a touch and go when they departed north, in the direction of the accident site. There were no witnesses to the accident, but nearby residences reported an electrical power outage at the time of the accident. Two hills adjacent to the accident site had a single power pole at each of their summits that supported three transmission lines between them. The weight-shift-control trike collided with the transmission lines that spanned the valley and impacted the ground north of the transmission lines. Postaccident examination of the airframe and engine revealed no evidence of any preimpact mechanical malfunctions or failures that would have precluded normal operation.

About this page
Everything above comes from the NTSB's public accident database and is rewritten in plain English only where the NTSB used codes; the probable cause and narrative are the NTSB's own words. This site never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number WPR22LA258.
