9.  Wire Distortion Due to Excessive Tie Wrap Tension

As a result of cable mishandling, this wire, which was part of a flight cable, fractured and resulted in a intermittent open and failure during test. The most likely cause of this failure is a tie wrap fastened too tight around the wire bundle placing excessive stress on individual wires.
