## Discrepancy

DURING CRUISE FROM KGEG TO KBFI, PILOT REPORTED A VIBRATION IN THE AIRCRAFT THAT CORRESPONDED TO AIRCRAFT SPEED.  NO OTHER ABNORMALITIES DURING FLIGHT.  UPON LANDING AND A POST FLIGHT WALK AROUND, IT WAS NOTED THAT THE LH NOSE GEAR DOOR APPEARED TO BE LOOSE.  FURTHER INSPECTION REVEALED THE NOSE GEAR DOOR TORQUE TUBE HAD BROKEN FROM ITS WELD AT THE PIVOT POINT ON THE LH CONNECTION.  THE TORQUE TUBE WAS REMOVED AND REPLACED WITH THE NEW -10 UNIT PER THE AMM.  OPERATIONAL CHECKS WERE GOOD AND NO VIBRATIONS IN FLIGHT.  NO FURTHER ACTION REQUIRED.
