Narrative:

On oct/sun/05; I was assigned to a B767-400; aircraft #abcd. The aircraft was position on pad X approximately 100 ft away from the lights that are positioned along the aircraft parking area. The l-hand nose tire was worn to an unsafe condition. I proceeded to change the l-hand nose gear tire. Under adverse conditions of darkness and time constraints of aircraft movement; I neglected to place the washer on the axle after installation of the wheel assembly. The aircraft that was positioned on pad Y needed to be moved for an early flight that morning. I was also concerned about completing the assigned task of doing the service check on the #2 engine in the allotted time. Callback conversation with reporter revealed the following information: the reporter stated this was the first night assigned to the hangar line crew and felt it was necessary to complete all jobs assigned and not be a burden on the crew. The failure to install the axle washer was an unexplainable action and fortunately was discovered before the airplane was dispatched. The reporter stated the crew supervisor interviewed him after this incident and advised him to slow down.
