Narrative:

While working overtime in december 2009; in hangar 'a' on aircraft 'X' (A320); I was assigned to complete numerous cabin tasks; ie: water job card; seat audio job card; and cabin final checks. Aircraft 'X' was scheduled for return to service during my shift. After lunch I was instructed by my lead mechanic that seat assembly 6ABC was missing from coach and needed to be robbed from aircraft 'X' and installed on another A320; aircraft 'Y'; prior to my completion of the seat audio video job card. My lead also told me he would generate the non-routines (write-ups) for me to document my work and he would help me transport the seat from hangar 'a' to hangar 'D'. I removed the seat from aircraft 'X' and noted no discrepancies with seat. I transported and installed the robbed seat onto aircraft 'Y'; reference maintenance manual (MM) 25-21-41-401. I was unable to complete seat audio video test due to ending of shift. No discrepancies were noted during seat installation. I was notified approximately eleven days later that the seat I installed on aircraft 'Y' was the incorrect effectivity for the airbus A320. I assumed the lead that instructed me to the rob the seat had already checked proper effectivity before requesting to rob the seat; as there were several airbus aircraft in the hangars to choose from.
