Narrative:

On the evening of dec/sat/06; I was assigned to be the lead on aircraft XXX which was OTS for a tank dive. At XA30 my start time I received a turn over that (supplier) was on the aircraft with parts on hand. The part had been idented; ordered and delivered on a previous shift. They were purging the tanks before entering. I also was assigned to lead aircraft XXX gear extend/retract operations check. The tank diver finished installing the part around XE30. Leak checks were completed at XB30. I reviewed the contract maintenance paperwork and the attached form. They were all complete. I then proceeded to sign off the installed part number. Thinking that gmm xx-xx-xx would relieve me of any wrongdoing of the work being performed by (supplier). I then entered the installed part number in the maintenance computer after which I received a forced parts screen. I entered the required information on that and the page was accepted. I never physically checked the ipc because I was under the impression that according to bulletin; if there was an issue with the interchangeability of the parts maintenance computer would require me to provide an ipc reference.
