Narrative:

On jun/sat/02, an MEL placard was issued on aircraft. MEL #75-3A for an airbus 300 was given for a turbine active clearance system -- high pressure inoperative. When reviewing the PIREP which was a maintenance entry, I noticed that the discrepancy was that a manifold was damaged on the 4H engine low pressure turbine case cooling system. I immediately contacted ZZZ maintenance to confirm the maintenance entry was for the low pressure turbine case cooling instead of the high pressure cooling system. They assured me that the item was written correctly and that the placard was for the high pressure system. I confronted the technician specialist who issued the placard and proceeded to change (correct) the MEL reference to read 75-3B instead of 75-3A. In the process of creating an action to be taken item to correct the problem, I noticed that the bracket was removed and stored on the information line that the mechanic had inserted to help in curing the problem. From all this and after further review, a fellow technician noticed the high pressure manifold had a hole in it, which could be repaired and that the low pressure manifold bracket was damaged (cracked). The aircraft was immediately taken OTS for repairs at ZZZ. The point is that the wrong MEL was issued but corrected at that time. The damage was on the high pressure manifold which has been corrected now and that the aircraft is ok for service under the correct MEL 75-3B which from my opinion should have been more scrutinized before being issued by my fellow technician because now it holds me responsible, since I corrected the first issued MEL and the atbt for the problem.

Title: AN AIRBUS 300 WAS DISPATCHED AND OPERATED IN COMPLIANCE WITH AN INCORRECT MEL REF.

Narrative: ON JUN/SAT/02, AN MEL PLACARD WAS ISSUED ON ACFT. MEL #75-3A FOR AN AIRBUS 300 WAS GIVEN FOR A TURBINE ACTIVE CLRNC SYS -- HIGH PRESSURE INOP. WHEN REVIEWING THE PIREP WHICH WAS A MAINT ENTRY, I NOTICED THAT THE DISCREPANCY WAS THAT A MANIFOLD WAS DAMAGED ON THE 4H ENG LOW PRESSURE TURBINE CASE COOLING SYS. I IMMEDIATELY CONTACTED ZZZ MAINT TO CONFIRM THE MAINT ENTRY WAS FOR THE LOW PRESSURE TURBINE CASE COOLING INSTEAD OF THE HIGH PRESSURE COOLING SYS. THEY ASSURED ME THAT THE ITEM WAS WRITTEN CORRECTLY AND THAT THE PLACARD WAS FOR THE HIGH PRESSURE SYS. I CONFRONTED THE TECHNICIAN SPECIALIST WHO ISSUED THE PLACARD AND PROCEEDED TO CHANGE (CORRECT) THE MEL REF TO READ 75-3B INSTEAD OF 75-3A. IN THE PROCESS OF CREATING AN ACTION TO BE TAKEN ITEM TO CORRECT THE PROB, I NOTICED THAT THE BRACKET WAS REMOVED AND STORED ON THE INFO LINE THAT THE MECH HAD INSERTED TO HELP IN CURING THE PROB. FROM ALL THIS AND AFTER FURTHER REVIEW, A FELLOW TECHNICIAN NOTICED THE HIGH PRESSURE MANIFOLD HAD A HOLE IN IT, WHICH COULD BE REPAIRED AND THAT THE LOW PRESSURE MANIFOLD BRACKET WAS DAMAGED (CRACKED). THE ACFT WAS IMMEDIATELY TAKEN OTS FOR REPAIRS AT ZZZ. THE POINT IS THAT THE WRONG MEL WAS ISSUED BUT CORRECTED AT THAT TIME. THE DAMAGE WAS ON THE HIGH PRESSURE MANIFOLD WHICH HAS BEEN CORRECTED NOW AND THAT THE ACFT IS OK FOR SVC UNDER THE CORRECT MEL 75-3B WHICH FROM MY OPINION SHOULD HAVE BEEN MORE SCRUTINIZED BEFORE BEING ISSUED BY MY FELLOW TECHNICIAN BECAUSE NOW IT HOLDS ME RESPONSIBLE, SINCE I CORRECTED THE FIRST ISSUED MEL AND THE ATBT FOR THE PROB.
