NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

The airplane impacted a power line while maneuvering. A witness observed the airplane overflying the pilot's private airstrip from south to north at about the same level as the power lines, which were located approximately 300 yards north of the grass runway. As the airplane neared the wires, its nose pitched up without the pilot adding power. The airplane struck the southern top static wire and subsequently impacted the ground 179 feet north of the power lines. The witness reported that the engine sounded 'great.' According to local residents, the pilot would normally takeoff to the south and land to the north. Examination of the airplane revealed that the left main landing gear tire had a straight-line abrasion across the tire tread extending around the inside edge of the tire. The left lower strut/axle had scrape marks on the leading edge from the brake hose clamp down to the wheel attachment bolts. The right main landing gear tire also had a straight-line abrasion across the tire tread extending around the outside edge of the tire. Continuity was established to all flight controls.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's failure to maintain obstacle clearance.
