## Discrepancy

DURING TAXI, THE NOSE WHEEL STEERING BECAME INEFFECTIVE IN A TURN TO THE LEFT.  UPON INVESTIGATION, MAINTENANCE FOUND STEERING UNIVERSAL JOINT IN GEARBOX (LEFT SIDE COCKPIT SIDE PANEL) FAILED.  REMOVED AND REPLACED BOTH UNIVERSAL JOINTS ON STEERING LINK IAW AMM 32-50-10.  AIRCRAFT TAXI CHECK GOOD.  THIS IS THE THIRD OCCURRENCE OF THIS PART FAILURE IN THE PAST MONTH, ALL ON DIFFERENT AIRCRAFT.
