Narrative:

On feb/sun/04, I was working on aircraft X, a B737 at air carrier X hangar at ZZZ airport. I had been working with a co-worker on a spoiler lube and inspection work card. We had split the work package up where I took the l-hand side of the aircraft and the removal/installation of the upper panels on both sides. We had finished our lube work and started to close up our access panels. I first installed the upper r-hand wing panel. Then I moved over to install the l-hand lower 2 panels. I had several stripped screw heads on one of the lower l-hand panels so I had to hunt down for new fasteners for it. Then I continued to finish up the rest of the job. 3 days later (mar/wed/04) my co-worker for the previous night called me at home to tell me that on taxi out, the morning after our work, aircraft X turned back to the gate because a passenger noticed the access panel on the upper l-hand wing fall off of the airplane. This is an oversight on my part. I should have double-checked my work or had asked someone else to check it. I think some of the contributing factors may have been that aircraft X is a new company for me, I have only been there 1 month and am still getting used to the environment and locations of equipment, fasteners, parts, etc. This was also only the 2ND time I performed that work card and not every aspect of that job. It was also late at night and I was tired.
