Probable cause
The pilot's failure to maintain clearance from marked transmission lines while on final approach.
NTSB analysis
The pilot entered the traffic pattern in the single seat, tail-wheel-equipped, experimental airplane for landing to runway 35. When he turned to final approach "everything looked normal." On short final, the pilot stated that he saw orange markers on wires just prior to contact with transmission lines. After cutting through two transmission lines, the pilot aborted the landing and performed a go-around. A visual inspection from another aircraft confirmed that the landing gear appeared to be intact. The pilot stated that the airplane was "shaking violently," but was controllable, and the pilot landed safely. The pilot shut down after landing and exited the aircraft normally. A Federal Aviation Administration inspector responded to the scene and confirmed substantial damage to the main wing spar, left aileron, and landing gear. One propeller blade was missing approximately 18 inches. The electrical transmission lines were replaced by the local power company.
