## Discrepancy

AFTER 1 MINUTE INTO A FLIGHT, A LOUD BANG WAS HEARD FROM THE REAR OF THE AIRCRAFT WITH A RIGHT YAW AND NOSE DOWN PITCH.  PILOT HAD NO PEDAL CONTROL.  THE PILOT PERFORMED A RUN-ON LANDING WITH NO DAMAGE TO AIRCRAFT.  THE TAIL ROTOR GEARBOX DEPARTED THE AIRCRAFT.  NO CAUSE HAS BEEN DETERMINED.  THE FAA, NTSB, AND BELL HELICOPTER ARE INVESTIGATING.  A DAILY INSPECTION OF THE T/R DRIVE SYSTEM HAS BEEN IMPLEMENTED UNTIL FURTHER NOTICE.
