Probable cause

Inadequate visual lookout by the pilot (failed to see & avoid) which resulted in his failure to maintain clearance from the obstruction. Contributing factors were: the unmarked guy wire & the pilot's lack of visual cues (visual perception).

Analysis

As the pilot was making a swath run near a major power line, the acft's right wing hit a guy wire that was anchored about 95 ft to the side of the power line. The guy wire severed the right wing & the acft crashed. The plt rprtd that if the unmarked guy wire had been more visible, the acdnt would not have occurred.
