## Discrepancy

AS THE ENGINEER WAS CONDUCTING A DAILY CHECK WITH THE PILOTS, IT WAS NOTED UNUSUAL AMOUNT OF MOVEMENT OF THE T/R BLADE TO THE HUB ASSEMBLY.  FURTHER INVESTIGATION IT WAS REVEALED THAT THE STAKED SLEEVE ONTO THE T/R BLADE AND THE SPHERICAL FEATHERING BEARING WAS LOOSE.  THE LOOSENESS WAS BETWEEN THE SLEEVE AND THE T/R BLADE.  THE SPHERICAL BEARING WAS A OLDER P/N BEARING THE BLADE WAS SENT AWAY FOR REPAIR.
