Narrative:

After tow bar released, aircraft was moved forward about 1 to 2 ft, before lineman gave waveoff. Aircraft struck tow bar and damaged nose brake assembly. Aircraft returned to gate and replaced left nose wheel brake. Supplemental information from acn 206326: the pushback was complete, the tug was pulled back from the aircraft and I had received verbal wave-off from the tug driver. As we were completing the before- taxi checklist. I noticed a truck heading for the tug and wondered if it was going to stop in time. I reached up and turned on the left wing flood light in order to get the attention of the truck driver so he would stop, which he did. Next, I looked around and there was no ground marshaller. This is not unusual as many time the marshaller is in a different position than left front of the aircraft. (Such as on the right side of the aircraft or on the tug itself). Seeing the tug backed away from the aircraft, and the absence of a ground marshaller, and having received a verbal wave off from the tug driver, I advanced the power to move the aircraft up to the 'circle.' as the aircraft moved forward approximately 1 - 2 ft, it struck the tow bar.

Title: ACFT LGT ACFT DAMAGED DURING RAMP OP RAMP DEP PROC PUSHBACK TOW OUT.

Narrative: AFTER TOW BAR RELEASED, ACFT WAS MOVED FORWARD ABOUT 1 TO 2 FT, BEFORE LINEMAN GAVE WAVEOFF. ACFT STRUCK TOW BAR AND DAMAGED NOSE BRAKE ASSEMBLY. ACFT RETURNED TO GATE AND REPLACED L NOSE WHEEL BRAKE. SUPPLEMENTAL INFO FROM ACN 206326: THE PUSHBACK WAS COMPLETE, THE TUG WAS PULLED BACK FROM THE ACFT AND I HAD RECEIVED VERBAL WAVE-OFF FROM THE TUG DRIVER. AS WE WERE COMPLETING THE BEFORE- TAXI CHKLIST. I NOTICED A TRUCK HDG FOR THE TUG AND WONDERED IF IT WAS GOING TO STOP IN TIME. I REACHED UP AND TURNED ON THE L WING FLOOD LIGHT IN ORDER TO GET THE ATTN OF THE TRUCK DRIVER SO HE WOULD STOP, WHICH HE DID. NEXT, I LOOKED AROUND AND THERE WAS NO GND MARSHALLER. THIS IS NOT UNUSUAL AS MANY TIME THE MARSHALLER IS IN A DIFFERENT POS THAN L FRONT OF THE ACFT. (SUCH AS ON THE R SIDE OF THE ACFT OR ON THE TUG ITSELF). SEEING THE TUG BACKED AWAY FROM THE ACFT, AND THE ABSENCE OF A GND MARSHALLER, AND HAVING RECEIVED A VERBAL WAVE OFF FROM THE TUG DRIVER, I ADVANCED THE PWR TO MOVE THE ACFT UP TO THE 'CIRCLE.' AS THE ACFT MOVED FORWARD APPROX 1 - 2 FT, IT STRUCK THE TOW BAR.
