'iCarly' -- Stuntwoman Sues After High-Wire Stunt FAILS

A stuntwoman from "iCarly" claims the production ruined her career by recklessly dropping her from high above the ground ... causing gruesome injuries.

Katina Waters claims in a new lawsuit she was hired for a stunt on "iCarly" ... where she would be slowly lowered to the ground while attached to a wire. Instead ... she claims the person operating "the descender machine" dropped her without warning ... and she crashed to the floor.

Waters -- a 40-year old stunt actor who's performed in dozens of TV shows and movies -- says the landing caused severe injuries to her leg, including fractured bones and torn ligaments.
