What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Statement from the privacy data omitted/operator and PIC said that a week prior to the accident he removed the throttle cable to reroute some wires. When he reinstalled the cable he replaced the nut with a nut that didn't allow the proper thread protrusion. He intended on replacing the nut with an appropriate one, but forgot. This may have cause the nut to fall off and the throttle cable to disconnect during the accident flight.
