## Probable cause

The pilot's failure to ensure that the helicopter was properly loaded, which resulted in the helicopter being in excess of its maximum allowable gross weight and led to a loss of main rotor rpm on takeoff. Contributing to the accident were the ground crewman's inadvertent overloading of the helicopter and the design of the spray tank's visual sight glass, which did not allow the pilot to visually verify the amount of the spray tank load without exiting the helicopter.
