Incident Overview
A helicopter pilot reported that while conducting a high reconnaissance of a field intended for agricultural application, he observed power lines surrounding the field. The pilot initiated the application southbound from the northwest section of the field. After traveling approximately 300 yards at an altitude of about 15 feet above the ground, the helicopter struck a power line. Following the impact, the pilot was able to land the helicopter in an adjacent field without further incident.
Damage and Mechanical Condition
The helicopter sustained substantial damage to the main rotor blade as a result of the power line strike. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation. No other damage or injuries were reported.
Pilot Actions
The pilot had conducted a high reconnaissance prior to the application flight, during which he identified the presence of power lines surrounding the field. Despite this awareness, the helicopter came into contact with a line while operating at low altitude during the spraying pass.
