Narrative:

I submitted a request for left [engine] pressure regulating and shut-off valve (prsov) for ZZZ maintenance- workload schedule. Mr. Y asked if alternate part number was effective. I then looked up the item and notified mr. Y and my supervisor; mr. X; that it looks like it was effective. Part was shipped from ZZZ1; air carrier Y's stores; [the loaner] part was received in ZZZ approximately xa:15pm local [time] and installed. I am not sure if ZZZ maintenance verified the illustrated parts catalog (ipc) before installation. I was notified three days later by my supervisor; mr. Y; that the wrong part was installed. While removing the loaner prsov - it was noticed that the wrong effectivity part was installed and replaced with the correct effectivity part. The B767-300 returned to the blocks in ZZZ due to bleed light displayed on overhead panel-(no engine pneumatics); [but] required for ETOPS service. Bite test indicated left prsov- incorrect part was found during replacement of left prsov loaner part - correct part has been installed. I would suggest when an aircraft is in an aircraft on ground (aog) situation; the station with the aog situation should submit the part number they want - also maybe when looking up correct effectivity; it should be double checked by a manager or supervisor.

Title: A Maintenance Controller and Maintenance Supervisor describe their involvement with a loaned; Non-ETOPS Pressure Regulating Shut-off Valve (PSROV) that was installed on the left engine of a B767-300ER ETOPS Category aircraft. The B767 returned to field due to lack of Engine Bleed Air.
