## Discrepancy

DURING POST-CRASH EXAMINATION OF THE ANTI-TORQUE CONTROL SYSTEM, FRACTURES WERE FOUND OF THE PUSH/PULL TYPE THRUSTER CONTROL CABLES P/N 500N7201-5 AND -37.  THE FORWARD CABLE FRACTURED AT THE SWIVEL BALL JOINT ALLOWING THE HOUSING TO SEPARATE BY 2.95 INCHES.  RIGHT PEDAL INPUT CAUSED BOWING OF THE INTERNAL CABLE/WIRE AND NO THRUSTER DIRECTION CHANGE.  SB AND AD TO BE ISSUED.
