Narrative:

Sep/xa/99, air carrier flight abc at gate xy in ZZZ, aircraft xyz at approximately XA12. Aircraft came in contact with a lavatory service truck. At approximately XA06 I proceeded to pull the aircraft chocks and start the door and panel check by walking around the perimeter of the aircraft. At ap-proximity XA07 I was standing by the push tractor waiting for customer service to pull jetway away from the aircraft. Approximately XA08, customer service pulled the jetway. At this point I again checked to see if anything was behind the aircraft. Then I entered the push tractor and contacted the crew and stated 'we are locked up, stand by for pushback clearance.' at approximately XA09, crew reported 'clear to push, brakes are set.' at approximately XA10, I requested 'brake off' and received 'brakes are off' message from crew. At approximately XA11, reported to crew 'pushing back, clear to start both engines.' at this point I checked for traffic by stooping down in tug and proceeded to push aircraft back. At approximately XA12, after pushing back aircraft about 10 ft, I saw a lavatory service man running from behind aircraft, outboard of #2 engine. I stopped the aircraft and stated to flight crew that 'we have a problem and to set brakes.' also that 'I will be off the head set to see what happened.' at approximately XA13, I went back to the aft of the aircraft and looked to see what the problem was. I saw that the aircraft had contacted the lavatory truck and that the lavatory service panel was open.
