Narrative:

While re-paneling the upper thrust reverser panels during a phase inspection; I had finished the #1 engine and was going to get more screws when I was interrupted to assist in the reinstallation of the engine cowls. Upon completion of the cowl installation; I found myself on the floor; where I re-paneled the lower thrust reversers. Upon completion of these panels I signed my work card; turned it in and forgot to secure the upper panel on the #2 engine. Normally; when I re-panel the engines during an inspection; I start with the top panels and finish with the bottom panels. When I stopped to assist with the installation of the #1 engine cowl; my routine was interrupted and I became distraction so that I forgot to complete the upper panel on engine #2.
