Aircraft Accident/Incident Report

Carnation, Washington 98014
Sunday, December 6, 1998 12:00 PST

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that while doing a low pass over a relative's farm, he struck a wire that was approximately 50 feet above ground level. He also reported that a combination of clouds and the sun made the wires 'virtually invisible' until the helicopter struck them. He reported that after striking the wire, the helicopter started to shake violently and he initiated a forced landing. During the forced landing the helicopter landed hard in approximately two feet of water.

NTSB Probable Cause Narrative

The pilot's failure to maintain clearance with a wire. Related factors were the pilot's performance of a low pass, a transmission wire, and difficulty encountered by the pilot in detecting the wire visually.
