## Discrepancy

ACFT WAS IN FOR 100 HR CHECK.  THE BRAKE LININGS WERE BEING REPLACED.  MX RECEIVED NEW LININGS.  AFTER INSTALLATION THE WHEEL WOULD NOT TURN.  BRAKE LININGS WERE REMOVED AND IT WAS NOTED THAT 1 LINING WAS OF A DIFFERENT SIZE THAN THE OTHERS, BUT WAS STAMPED WITH THE CORRECT P/N AND HAD COME OUT OF THE SAME BOX AS ALL THE OTHER LININGS THAT HAD BEEN REPLACED. THE LINING WAS REPLACED WITHOUT INCIDENT AND THE MISSIZED LINING QUARANTINED.
