Narrative:

While working my regular shift on may 2009; I was made aware that a B757-200 aircraft had been found to have the pitot lines disconnected and capped at the elevator feel computer. This was found by YYY station maintenance. This aircraft had very recently had a c-check accomplished at ZZZ. I do a relatively high percentage of the air data checks accomplished in the hangar. I reviewed this paper package and found that I had signed for returning the aircraft to normal configuration following altimeter checks. After reviewing the package I recalled some details. The altimeter accuracy checks were accomplished by another amt on swing shift. On odd numbered c-check visits; we only accomplish altimeter accuracy check along with a separate card to check the ATC system. ATC had failed on the right system. The following day I replaced the ATC coupler; accomplished checks and removed the equipment.
