Two mechanics report discrepancies with confirmation checks that were accomplished on a service work card and a chip detector card for the #2 engine of a B737-800 aircraft. Signature blocks on the work cards that should have had not applicable (north/a) entered were left blank. Qualifications of mechanic doing confirmation checks had previously expired.

Narrative:
October 2011; I was assigned to perform maintenance on three aircraft for the graveyard shift. I was working with fellow mechanic Y. We were assigned to perform a service work card in addition to a chip detector card for the number two engine. Mechanic Y performed the maintenance function of the work card and I [confirmed] his work. The error I made was that I am not rii qualified. My qualification had expired some time ago. I was not aware at the time that the work card required an rii qualification check; I thought that it just required a confirmation check. We had a very heavy work load that night and knew that there where some changes that occurred previously by maintenance and engineering concerning confirmation and rii sign-offs. I would not have [confirmed] the maintenance work if I knew I was not qualified to sign the check off. I am now aware of my actions and I will say that the error will never occur again. I would like to see more information made available when changes occur within our maintenance and engineering department concerning paperwork. I have to put blame on myself for not being aware of the necessary qualification involved in the confirmation check sign-off.
