Human Factors
Flight was dispatched and incurred Number (1) engine generator issues and needed to RTBL (return to blocks) for maintenance. We went back out to marshall plane back in and were short the second (2) wing walker because the rest of crew was sent to other assignments. We activated the (Accu-Park) red stop lights and were waiting on the second marshaller when the crew spooled up the engines and proceeded to pull into the gate. At NO time was the green light on (Accu-Park) activated or a manual hand signal given to pull in to gate envelope. The aircraft proceeded to pass its stop mark by thirty (30) plus feet and stop nose gear almost to inner VSR. This also brought the wing and Number one (1) engine within ten (10) to fifteen (15) feet of striking second jet bridge. Refer to Supervisor's pictures from all angles to get perspective needed to reference this incident. Once the crew decided where they wanted to stop we chocked aircraft and waited for direction from the Company. After taking pictures we proceeded to push aircraft thirty feet back to the appropriate stop mark for a B767-400.
Aircraft Marshall reports a B767-400 returning to the gate for maintenance but with insufficient manpower the Captain is instructed to wait. The Captain elects to self park; missing the stop point by 30 feet with no other ill effects.
