Accident Overview
A helicopter conducting an agricultural application flight experienced a loss of rotor RPM during a low-level turn. The pilot reported that after completing the turn, the rotor RPM was lower than normal. Environmental conditions included a temperature of approximately 74 degrees Fahrenheit and high humidity, with a density altitude of about 2,000 feet.
Sequence of Events

Conditions
The ambient temperature was reported as 74°F, and the pilot noted high humidity. The density altitude was calculated to be approximately 2,000 feet.
Outcome
The helicopter sustained damage from the impact with the crop and the overturn. No further details were provided regarding injuries or the extent of damage.
