The pilot was about to start agricultural operations, and had turned on the fertilizer bucket, when he reported that the hydraulic gauges started to 'surge.' He said the helicopter, '...then took a violent turn to the left...the helicopter jerked for a third time and came back level.' He released the fertilizer bucket, and elected to make a forced landing. He stated, '...the control was going left to right, the collective was not reacting properly, so I spooled off the throttle and landed in the trees.' Examination of the helicopter's hydraulic system after the accident revealed that impact damage had destroyed the servos and the hydraulic fluid reservoir. No discrepancies were found with the hydraulic system.
Probable Cause: The pilot's loss of control as a result of erratic flight control movement due to a surge in hydraulic pressure for undetermined reasons.
