Narrative:

I was just made aware of a maintenance violation that occurred on aircraft X. I was assigned a tire change on this aircraft with other amt's. I installed the pins as required and documented that action in the log book. The routine tire change was all but routine. The equipment required for the tire change proved to be a rather distracting event. Two things; the first being there was no nitrogen in any of the bottles on the nitrogen cart and secondly it took three jacks before we found one that worked. I pulled two of the three pins the right main and the nose gear and left the left main gear. I'm really not sure what I was thinking at that moment other than let's hurry up and get these people out of here and inadvertently missed the other pin. I know it is my responsibility when it comes to correctly addressing the log book and all the associated maintenance for which I take accomplishment for. However due to the fiasco in the tire change I felt rushed and lost track of what I believed to be the proper amount of pins that were to be pulled.
