Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot had flown multiple trips into and out of the ranch prior to the accident. He also had seen wires in the area and had a discussion with local fishing guides regarding the location of wires in the area. As the pilot was preparing to depart the ranch with the last load of passengers he was approached by a guide who wanted to video the helicopter for their website. The pilot agreed and after lifting off, made a pass near the ranch for the video. The pilot stated he was flying toward the mountains when he heard a "small ting" and he knew the helicopter contacted a wire. He made an uneventful off airport landing in a nearby clearing. Although the pilot stated he never saw the wire it was later determined the helicopter contacted was a small copper static wire. A postaccident inspection of the helicopter revealed two of the three main rotor blades were beyond repair, at least two of the Fenestron blades were beyond repair, and the entire Fenestron stator blade assembly needed to be replaced.

Factual narrative

The pilot stated he made two flights to the ranch to drop passengers off and was on his second flight transporting the passengers out of the ranch when the accident occurred. The pilot stated he had seen some wires in the area and had a discussion with the local fishing guides about the location of wires in the area, how dangerous the wires were, and how hard they were to see. The pilot reported that as he was preparing to depart with the last load of passenger, one of the fishing guides asked if he could video the helicopter for their website. The pilot reported he agreed and discussed where he would fly so the helicopter could be filmed. The pilot took off and flew a pass for the video. He stated he was flying toward the mountains when he heard a "small ting." The pilot reported he knew he hit a wire from the sound, but he did not see it. He made an uneventful off airport landing in the nearest clearing. The pilot reported the wire that the helicopter contacted was a small copper static wire. A postaccident inspection of the helicopter revealed two of the three main rotor blades were beyond repair, at least two of the Fenestron blades were beyond repair, and the entire Fenestron stator blade assembly needed to be replaced.
