Summary
On May 10, 2017, a Robinson Helicopter Company R44 (N428JG) was involved in an incident near Vevay, IN. All 1 person aboard were uninjured. The aircraft sustained substantial damage.
The National Transportation Safety Board determined the probable cause of this incident to be: The pilot’s failure to see and avoid power lines during an agricultural application flight due to distraction when reading a map.
The pilot reported that he accomplished a high reconnaissance before maneuvering to descend for an aerial application. He recalled that his attention was split between visually acquiring the intended application area and the indications on his digital map mounted in the cockpit. He descended below a tree line into the intended application area, but "I was still attempting to compare the crop on my field to my map, and was not looking outside the aircraft as diligently as required." He diverted his attention outside the cockpit and noticed powerline wires at eye level. He asserted that he immediately lowered the collective and applied forward cyclic, but the main rotor mast struck the powerline wires.
This incident is documented in NTSB report GAA17CA279. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N428JG.

Analysis

He recalled that his attention was split between visually acquiring the intended application area and the indications on his digital map mounted in the cockpit. He descended below a tree line into the intended application area, but "I was still attempting to compare the crop on my field to my map, and was not looking outside the aircraft as diligently as required." He diverted his attention outside the cockpit and noticed powerline wires at eye level. He asserted that he immediately lowered the collective and applied forward cyclic, but the main rotor mast struck the powerline wires. He landed the helicopter in the field, however, the main rotor blades sustained substantial damage.
The pilot reported that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
