Narrative:

What typically occurs when an aircraft has arrived at the gate with a worn tire is the technician that discovered it will use the 2-WAY radio to alert the lead (and the rest of the crew) that a tire change is needed. The lead will make sure there are enough people to help remove and replace it and complete the paperwork on time. While one person is getting the required tooling and paperwork, another may be getting the logbook and another may be getting a new tire assembly. Work begins as soon as possible by working together, keeping in mind the short ground time between most flts. To get the job done in the time allotted, without a delay, takes more than 1 person. I don't recall what transpired that day when the washer was inadvertently left off the axle. I do know that I signed the log page believing that that work was performed correctly by me and all those involved in accordance with the aircraft maintenance manual. It was discovered and corrected 4 days later by someone else. (No damage to aircraft -- inspected and installed washer during ground time.)
