What was found
(CAN) AFTER LANDING, THE AIRCRAFT FELT A SHIMMY VIBRATION. AT THE GATE THE PILOT NOTICED A BROKEN PIECE MISSING OFF THE NOSE STEERING COLLAR YOKE ASSY. AFTER INVESTIGATION THE PART INSTALLED IS PRE SB32-099 WHICH CALLS FOR REGULAR INSPECTION DUE TO THAT SAME REASON AS NAMED ABOVE. AT THIS MOMENT THIS IS NOT A MANDATORY SB OR AD. WE WILL BE IMPLEMENTING THE SB WITH THE NEW PN 3931074101 AS PART OF OUR FLEET RELIABILITY PROGRAM.
