The pilot flew to an off-airport location to pick up an electrical company employee. After being on the ground about eight minutes, the pilot and passenger then flew power line patrol looking for vegetation encroachment. One hour and 36 minutes after taking off one of the helicopter's main rotor blades impacted the middle strand of a crossing high voltage transmission line. The helicopter was destroyed by impact forces and postimpact fire. The impacted transmission line was approximately 100 feet above and crossed perpendicularly to the transmission line they were following. Examination of the helicopter wreckage revealed no preexisting anomalies that would have contributed to the accident.
Probable Cause: The pilot's failure to maintain clearance from the crossing transmission line.
