## Discrepancy

ON TAKEOFF PILOT REALIZED HE HAD NO ANTI-TORQUE INPUT WITH LEFT PEDAL INPUT. THE PILOT LOWERED THE COLLECTIVE IMMEDIATELY BUT THE AIRCRAFT ROTATED 180 DEGREES BEFORE COMING TO REST. UPON INSPECTION IT WAS FOUND THE RH THRUSTER CABLE WAS BROKEN APPROXIMATELY AT THE 90 DEGREE PULLEY ON THE LEFT SIDE OF THE STATIONARY CONE.
