## Discrepancy

DURING LANDING,  EXPERIENCED NOSE WHEEL SHIMMY AFTER TWO LANDINGS FROM PREVIOUS NOSE STRUT SERVCING.  MECHANIC REMOVED THE NOSE STRUT FOR SERVICING PROCEDURE.  STRUT WAS INSPECTED AND A .3750" CRACK IN THE STRUT CYLINDER HSG WAS FOUND AT THE RECESSED AREA FOR THE LOCKING KEY.  THE CRACK EXTENDS THROUGH THE CYLINDER MATERIAL AND INTO THE INTERNAL CYLINDER THREADS.  CRACK WAS CONFIRMED WITH NDI STANDARD PRACTICES. CYLINDER WAS CONDEMNED WITH A RED TAG SINCE THE AMM DOES NOT ALLOW FOR ANY CYLINDER CRACK REPAIRS.
