## Discrepancy

ON APPROACH FOR LANDING, LANDING GEAR WOULD NOT EXTEND ELECTRICALLY AND AN ODOR WAS NOTICED IN THE COCKPIT.  THE GEAR WAS EXTENDED MANUALLY, BUT A LOUD POPPING NOISE WAS HEARD UPON EXTENSION.  INSPECTION OF THE GEAR AFTER LANDING FOUND RT UPLOCK ROLLER SEIZED.  THIS ROLLER WOULD NOT DISENGAGE FROM PN 35-845077-22 RT UPLOCK BLOCK; THUS, ALLOWING GEAR MOTOR TO BURN OUT AND BEND THE RT GEAR RETRACT ROD PN 60-810057-617.  THE MM CALLS OUT AN INSPECTION AND LUBRICATION OF THIS ROLLER EACH 100 HOURS OF OPERATION.
