Read the full NTSB narrative

THE PURPOSE OF THE LCL FLIGHT WAS FOR THE CFI TO DEMO THE NEWLY ACQUIRED HELICOPTER TO ITS OWNER. THE CFI REPORTED THAT DURING THE FLT A 'SOMEWHAT COMMON' VIBRATION WAS DETECTED, & HE ASSOCIATED THE VIBRATION WITH THE ACFT'S WOODEN MAIN ROTOR BLADES. HE FURTHER REPORTED THAT HE MAY HAVE BEEN DISTRACTED BY THE VIBRATION, & HE FAILED TO OBSERVE THE POWER LINES WHICH WERE IN THE LANDING APPROACH PATH. AT ABOUT 60 FT AGL THE ACFT'S MAST COLLIDED WITH THE WIRES. CONTROL WAS LOST, & DURING THE HARD LANDING THE BLADES FLEXED DOWN CUTTING OFF THE TAIL BOOM.
