Narrative:

2 log page write-ups on same lavatory: 1) waste container access door; and 2) waste container flap. First write-up was maintenance controller deferred but should have been on MEL. Second write-up was cleared. There was a placard in the book for an MEL; but no MEL on log page. I pulled the placard and cleared the bins and waste container flap write-up reference on a new log page entry after checking that container flap was repaired. The access door was still an opened item but I closed it on the new log page thinking they were duplicate write-ups. The confusion occurred when the maintenance controller deferral on access door should have been on MEL and the placard I removed should have been completed with the employee name and number. No name or number was on the placard. Just the aircraft number; discrepancy; and MEL 38-22-04 and log page number that was designated as maintenance controller deferral. Aircraft departed and my lead informed me that the log page in question was still open and was improperly deferred so he notified maintenance control to have them crew defer the waste access door and close the lavatory.

Title: AN A320 LAVATORY TRASH BIN WAS DEFERRED IMPROPERLY BY A TECHNICIAN. TRASH BINS NEEDED MAINT CTLR APPROVAL. LAVATORY CLOSED AND LOCKED.

Narrative: 2 LOG PAGE WRITE-UPS ON SAME LAVATORY: 1) WASTE CONTAINER ACCESS DOOR; AND 2) WASTE CONTAINER FLAP. FIRST WRITE-UP WAS MAINT CTLR DEFERRED BUT SHOULD HAVE BEEN ON MEL. SECOND WRITE-UP WAS CLRED. THERE WAS A PLACARD IN THE BOOK FOR AN MEL; BUT NO MEL ON LOG PAGE. I PULLED THE PLACARD AND CLRED THE BINS AND WASTE CONTAINER FLAP WRITE-UP REF ON A NEW LOG PAGE ENTRY AFTER CHKING THAT CONTAINER FLAP WAS REPAIRED. THE ACCESS DOOR WAS STILL AN OPENED ITEM BUT I CLOSED IT ON THE NEW LOG PAGE THINKING THEY WERE DUPLICATE WRITE-UPS. THE CONFUSION OCCURRED WHEN THE MAINT CTLR DEFERRAL ON ACCESS DOOR SHOULD HAVE BEEN ON MEL AND THE PLACARD I REMOVED SHOULD HAVE BEEN COMPLETED WITH THE EMPLOYEE NAME AND NUMBER. NO NAME OR NUMBER WAS ON THE PLACARD. JUST THE ACFT NUMBER; DISCREPANCY; AND MEL 38-22-04 AND LOG PAGE NUMBER THAT WAS DESIGNATED AS MAINT CTLR DEFERRAL. ACFT DEPARTED AND MY LEAD INFORMED ME THAT THE LOG PAGE IN QUESTION WAS STILL OPEN AND WAS IMPROPERLY DEFERRED SO HE NOTIFIED MAINT CTL TO HAVE THEM CREW DEFER THE WASTE ACCESS DOOR AND CLOSE THE LAVATORY.
