On January 4, 1984, a Bell 47G-2 (registration N10194) operated by Helicare Ag, Inc. was involved in an aviation accident near Watsonville, CA. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A helicopter's rotor blades struck a standpipe during a swath run at a field edge, causing the aircraft to contact the ground approximately 25 feet beyond the obstruction and sustain additional damage.
Incident Description
During a swath run at the edge of a field, the pilot of a helicopter approached a standpipe. In an attempt to avoid the obstruction, the pilot applied control pressure. However, the outer 3 inches of the rotor blades struck the standpipe. The helicopter then contacted the ground about 25 feet beyond the standpipe, and the aircraft sustained further damage.
Pilot's Statement
The pilot reported that he was accustomed to flying a helicopter equipped with longer spray booms. He noted that the short booms on the aircraft involved in the incident were not as effective for visual reference during maneuvering.
Damage
The initial impact with the standpipe damaged the outer portion of the rotor blades. The subsequent ground contact resulted in additional damage to the helicopter.
