Narrative:
After spraying a field during an aerial application flight, the pilot returned to the helispot to reload. Approaching the helispot, he flew past 30-foot-tall almond trees and 10-foot-tall oleander bushes at a low altitude. Immediately thereafter the helicopter began yawing. The pilot stated that 'the tail rotor felt sluggish,' and control was lost. The pilot further reported that he believes the spray boom clipped the vegetation. The helicopter came to rest on its side. At the time of the accident, the local wind condition was described by both the pilot and a ground witness as being light and variable. The pilot did not assert that any mechanical malfunctions precipitated the accident.
Probable Cause: The pilot's failure to maintain clearance while landing in proximity to high vegetation, which resulted in the inadvertent contact of the spray boom to the trees.
