General Maintenance Action
Aircraft; Incorrect / Not Installed / Unavailable Part; Human Factors
Slide assemblies were removed and placed on jetway floor. At the same time; 5 cleaners showed up to clean the aircraft; and positions may have been disturbed by their traffic. Assemblies were inadvertently re-installed/swapped into wrong positions. Perhaps initiate protocol to prevent cleaners from accessing aircraft while maintenance is being performed (or require them to ask our permission for entry) in cabin/galley areas. Also; perhaps include a sign-off requiring visual confirmation of slide case-to-correct door orientation.
Both FWD door slides were removed and placed in the jetway. At that time there were several appearance techs moving about the jetway and aircraft. With all the people moving in and off the aircraft the slides were inadvertently put in the wrong forward positions. I was contacted by my coworker about the situation. And was informed that the problem was fixed by another AMT.
B737 Maintenance crew reported that the Emergency Door Slides were inadvertently installed on the incorrect door.
