N41830

On July 8, 2019, about 1112 central daylight time, a Continental Copters Tomcat MK6C, N41830, was substantially damaged while maneuvering near Franklin, Kentucky. The commercial pilot sustained minor injuries. The local aerial application flight was conducted under the provisions of Title 14 Code of Federal Regulations Part 137. Visual meteorological conditions prevailed and no flight plan was filed for the flight that departed a field near Franklin, Kentucky, about 1110.

The pilot stated that after 50 gallons of chemical and 5 gallons of fuel were added to the helicopter, he departed from a rooftop helipad of a truck in light and variable wind, to spray a field. As the helicopter turned, descended and leveled off to spray the field, the pilot realized that the main rotor rpm began to decay. He increased throttle, lowered the collective, and applied aft cyclic to increase rotor rpm, however, the tailboom contacted the ground and the helicopter rolled inverted. The pilot added that there were no preimpact mechanical malfunctions with the helicopter.

Examination of the wreckage by a Federal Aviation Administration inspector revealed damage to the main rotor blades, tailrotor, fuselage, and tailboom.
