Narrative:

At the shift beginning; I was assigned to an A320 aircraft to repair a broken spreader bar at seat 24 D/east. After waiting for gate calls; I proceeded to pick up my pre-drawn parts; then on to aircraft. Everything proceeded as planed until I went to check the security of the opposite side of the seat back pivot; [where] there were parts missing and the pivot bolts were broken and not secured to the pivot. I ran into trouble in gaining access to the area to do the repair. I called my lead mechanic; mr.X; to get some assistance at about xa:30 am in the morning. We were able to remove the armrest shroud and pivot bolt at about xa:45 am. At that point parts needed to be ordered. They took 45-minutes to be delivered and turned out to be the wrong parts. At that point my supervisor arrived at the aircraft and attempted to find the proper knuckle. We proceeded with a repair of the bad knuckle (nutplate). This brought us to about xb:45 am. I put everything together in about 10 minutes and proceeded in a hurry to clean up and on to get punched out by xc:30 am. As I was walking out the door of the hanger; it hit me that I had not installed two mounting nuts and bolts that secure the knuckle to the isle spreader bar. I immediately called my supervisor and informed him of my mistake. I kept in touch with him until the repair was done. My best assessment was that I was in a hurried situation and overlooked the securing bolts. I knew that I had not installed the bolt at the time and became overwhelmed with trying to tie up all of the loose ends. I was not in the area; however my supervisor and the dayshift lead; took charge of the repair. I need to learn to work situations with a little more calmness rather than trying to beat the clock.
