Mechanic reports he was informed by his Supervisor he had installed an incorrect cargo fire bottle in a B767-300; after using the company part number listed in the maintenance item.

Narrative

Feb/09; I was assigned to Aircraft X to finish the aircraft dayshift had been working on. I was informed by my Supervisor that all that was left was to install a cargo fire bottle that had a missing data plate on it; and install an aft cargo bin net that was robbed off of another aircraft. The Supervisor stated that the fire bottle had been pre-pulled and was located at maintenance. Me and my partner picked up the bottle and proceeded to aircraft to perform the maintenance. The maintenance item listed Part #X and that the manufacturer's part number should begin with 473957. I verified that the part number on the bottle matched those stated in the maintenance item and installed the bottle per the Aircraft Maintenance Manual. In February 2009 I was contacted at home by my Supervisor who told me that I had installed the incorrect bottle. The correct bottle was installed on the same day. Contributing factors: Using airline part numbers; incorrect information given in the maintenance item; failure to verify part numbers in the IPC. Ways to correct this problem: Verify part effectivity using the IPC by removing part numbering and ordering information from the maintenance item. Eliminating airline part numbers; and using only the manufacturer numbers.
