Incident Overview
A pilot operating a restricted category helicopter experienced a hard landing after departing from a farm field. The helicopter had been refilled with 80 gallons of defoliant prior to departure. The takeoff was conducted from a field adjacent to a country road.
Sequence of Events
The pilot had previously completed two departures from the same location and was aware of nearby power lines. During the climb over the power lines, the pilot permitted the engine, rotor rpm, and airspeed to decrease. Recognizing the situation, the pilot attempted to regain airspeed and rotor rpm by lowering the helicopter's nose. However, these efforts did not succeed, and the helicopter subsequently made a hard touchdown in the field.
Additional Information
The helicopter is categorized as restricted, which often imposes limitations on its operation. The pilot's previous familiarity with the departure site, including knowledge of the power lines, was noted. No further details about the helicopter's specifications, registration, or the outcome of the flight have been reported.
