Unsafe operation of Equipment

A contract crew was working on a helicopter set pole. The pilot, with a contract helicopter company, came in rapidly with the pole swinging violently. The crew said that they tried repeatedly to wave the pilot off, but he kept on. The result was that he broke the pole top off of the old pole to be changed out, severely damaged both phases of 4 ACSR, missed by inches a contract crew member, who dove to the ground for cover fearing the pilot would release his load and nearly cross phased the primary down the hill beyond the open point. The pilot denies it was his fault and stated that it was the crew who guided him in. The crew was shook up but went on with their work. The contract crew is currently contacting other vendors, and if they cannot find someone else to fly, they said they will cancel the next day’s helicopter work.
