Narrative:

On the night in question; I was informed by the lead that aircraft X received a bird strike on the nose radome. I was assigned to work a different aircraft; but was later reassigned to help with the removal and installation of the radome. I was told aircraft on ground had located a part at another air carrier and the leads went to pick it up. When the truck arrived with the part; I was told it was a crossreferenced part number; since the tag had a different part number. With the assistance of 3 mechanics and a lead; I installed the radome per the applicable maintenance manual. When the job was completed; I filled out the log page and entered the part number and serial number in my corrective action. During this maintenance procedure; I should have doublechked all part numbers and crossreferences. I should also have checked before hand effectivity myself. It would have also helped me if I ordered the part myself; and be more familiar with the ipc; effectivity; and part ordering procedures. I rely on a lot of teamwork; coming from the aircraft on ground desk; to the leads; then to me and my co-workers. The part was researched; called in the aircraft on ground; ordered; delivered to the aircraft. I did not verify that the part was the one ordered. The next time; I will be more careful in making sure the part installed is the correct effectivity. I think what else contributed to my mistake was I was assigned a different aircraft and then broke off to help with the radome so I was not involved with the part number research process from the beginning. Then; when we were sent the wrong radome ordered; I probably would have caught that discrepancy.

Title: B737-400 WAS DISPATCHED WITH THE INCORRECT RADOME INSTALLED.

Narrative: ON THE NIGHT IN QUESTION; I WAS INFORMED BY THE LEAD THAT ACFT X RECEIVED A BIRD STRIKE ON THE NOSE RADOME. I WAS ASSIGNED TO WORK A DIFFERENT ACFT; BUT WAS LATER REASSIGNED TO HELP WITH THE REMOVAL AND INSTALLATION OF THE RADOME. I WAS TOLD ACFT ON GND HAD LOCATED A PART AT ANOTHER ACR AND THE LEADS WENT TO PICK IT UP. WHEN THE TRUCK ARRIVED WITH THE PART; I WAS TOLD IT WAS A CROSSREFERENCED PART NUMBER; SINCE THE TAG HAD A DIFFERENT PART NUMBER. WITH THE ASSISTANCE OF 3 MECHS AND A LEAD; I INSTALLED THE RADOME PER THE APPLICABLE MAINT MANUAL. WHEN THE JOB WAS COMPLETED; I FILLED OUT THE LOG PAGE AND ENTERED THE PART NUMBER AND SERIAL NUMBER IN MY CORRECTIVE ACTION. DURING THIS MAINT PROC; I SHOULD HAVE DOUBLECHKED ALL PART NUMBERS AND CROSSREFERENCES. I SHOULD ALSO HAVE CHKED BEFORE HAND EFFECTIVITY MYSELF. IT WOULD HAVE ALSO HELPED ME IF I ORDERED THE PART MYSELF; AND BE MORE FAMILIAR WITH THE IPC; EFFECTIVITY; AND PART ORDERING PROCS. I RELY ON A LOT OF TEAMWORK; COMING FROM THE ACFT ON GND DESK; TO THE LEADS; THEN TO ME AND MY CO-WORKERS. THE PART WAS RESEARCHED; CALLED IN THE ACFT ON GND; ORDERED; DELIVERED TO THE ACFT. I DID NOT VERIFY THAT THE PART WAS THE ONE ORDERED. THE NEXT TIME; I WILL BE MORE CAREFUL IN MAKING SURE THE PART INSTALLED IS THE CORRECT EFFECTIVITY. I THINK WHAT ELSE CONTRIBUTED TO MY MISTAKE WAS I WAS ASSIGNED A DIFFERENT ACFT AND THEN BROKE OFF TO HELP WITH THE RADOME SO I WAS NOT INVOLVED WITH THE PART NUMBER RESEARCH PROCESS FROM THE BEGINNING. THEN; WHEN WE WERE SENT THE WRONG RADOME ORDERED; I PROBABLY WOULD HAVE CAUGHT THAT DISCREPANCY.
