Wisdom, Montana 59761
Saturday, August 24, 2002 16:00 MDT
NTSB Narrative Summary Released at Completion of Accident
The pilot reported that during a post-flight walk around, he noticed damage to the main rotor blades. One blade was punctured and both blades displayed tearing to the underside material of the blade. The pilot reported that several missions had been flown that day and he was unsure as to when the damage occurred. The pilot stated, that he believed that during one water drop with the 50-foot long line that held the water bucket, that the altitude was insufficient to avoid contact with an unseen tree top on the opposite side of the aircraft from the pilot station.
NTSB Probable Cause Narrative
The pilot's failure to maintain clearance from an object while maneuvering. A tree(s) was a factor.
