Narrative:

Engine build-up needed an MD80 engine run qualified person. I was assigned to run the engines for them. While engine build-up was finishing up prepping the engines; I was up in the flight deck filling out trim data on the task card. While pushing out of the hangar; I started the APU without any problems indicated. On jun/tue/06 I was informed that the #2 upper engine cowl was damaged by running the APU with the #2 upper cowl open. There was no tag-out of the APU switch; for having the cowl in the open position. I was given no indication from ground crew that the cowl was open. The assumption on my part was that the cowl was closed when cleared to start engines (past experiences with engine buildup was the cowl was either removed or closed).
