A FOKKER 100 WAS DISPATCHED WITH THE R MAIN GEAR WHEEL AND TIRE ASSEMBLY INSTALLED INCORRECTLY OMITTING THE BEARING SPACER.

Narrative

PERFORMED A FIRST TIME TRANSIT CHK. WHILE BEING WALKED THROUGH THE CHK BY ANOTHER TECHNICIAN; NOTHING UNUSUAL WAS NOTICED REGARDING THE ACFT. I WAS NOTIFIED THE FOLLOWING DAY THAT DURING THE DAY ONE OF THE ACFT TIRES BECAME LOOSE AND CAUSED DAMAGE. THIS PARTICULAR TYPE ACFT HAS BEEN NOTED FOR LEAVING THE SPACER OUT DURING TIRE CHANGES. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THAT NEITHER THE RPTR NOR THE MECH TRAINING THE RPTR WERE INVOLVED IN THE R MAIN GEAR TIRE AND WHEEL REPLACEMENT. THE RPTR SAID NO LOGBOOK WRITE-UPS WERE NOTED ON THE INBOUND FLT ABOUT WHEEL VIBRATION OR NOISE. THE RPTR STATED ON PUSHBACK THAT NO WHEEL WOBBLE WAS NOTED. THE RPTR SAID ON THE TIRE AND WHEEL CHANGE THE PAPERWORK HAS A SPECIAL TAG NOTING THE INSTALLATION OF THE SPACER. SUPPLEMENTAL INFO FROM ACN 390482: UPON INSPECTION ON THE GATE; THE WHEEL ASSEMBLY WAS COCKED ON THE BRAKE. THE WHEEL ASSEMBLY WAS REMOVED BY MAINT AND DISCOVERED THE SPACER MISSING. MAINT REPAIRED THE ACFT AND RETURNED IT TO SVC. I HAVE CHANGED MANY WHEEL ASSEMBLY ON THE F100 THIS IS A FIRST FOR ME. THE SPACER SOMETIMES STICKS TO THE BEARING ASSEMBLY ON REMOVAL AND I HAVE ALWAYS IN THE PAST CAUGHT IT IN TIME OR UPON RECHK. CALLBACK CONVERSATION WITH RPTR ON ACN 390482 REVEALED THE FOLLOWING INFO: THE RPTR STATED THE JOB CARD DID CALL OUT THE INSTALLATION OF THE SPACER BUT THE RPTR BELIEVES THE SPACER STUCK TO THE REMOVED BEARING AND WAS NOT NOTICED. THE RPTR SAID THE FAA HAS REQUESTED A WRITTEN STATEMENT OF THIS INCIDENT.
