Narrative:

During final boarding process aircraft rolled approximately 4 ft. I was on the loading bridge when I noticed the aircraft start to move. I ran to the aircraft and yelled for the first officer to apply brakes. The first officer stopped the aircraft with brakes. The aircraft forward entry door came in contact with the loading bridge. The aircraft was inspected by maintenance and only minor damage found. The aircraft was released for service. The tug was hooked to the aircraft and the tug engine was running. There was no operator on the tug. The aircraft parking brake was off, and no signal was given to either pilot to remove chocks. I believe making sure aircraft brakes are set before removing chocks and not leaving the tug engine running without an operator on the tug would have prevented this incident. Supplemental information from acn 318663: the aircraft would have continued backwards if I had not applied the brakes to stop it from rolling further. Parking brake in aircraft was off, no signal was given that the chocks had been removed.

Title: ACFT DAMAGED DURING LOADING PROC PAX.

Narrative: DURING FINAL BOARDING PROCESS ACFT ROLLED APPROX 4 FT. I WAS ON THE LOADING BRIDGE WHEN I NOTICED THE ACFT START TO MOVE. I RAN TO THE ACFT AND YELLED FOR THE FO TO APPLY BRAKES. THE FO STOPPED THE ACFT WITH BRAKES. THE ACFT FORWARD ENTRY DOOR CAME IN CONTACT WITH THE LOADING BRIDGE. THE ACFT WAS INSPECTED BY MAINT AND ONLY MINOR DAMAGE FOUND. THE ACFT WAS RELEASED FOR SVC. THE TUG WAS HOOKED TO THE ACFT AND THE TUG ENG WAS RUNNING. THERE WAS NO OPERATOR ON THE TUG. THE ACFT PARKING BRAKE WAS OFF, AND NO SIGNAL WAS GIVEN TO EITHER PLT TO REMOVE CHOCKS. I BELIEVE MAKING SURE ACFT BRAKES ARE SET BEFORE REMOVING CHOCKS AND NOT LEAVING THE TUG ENG RUNNING WITHOUT AN OPERATOR ON THE TUG WOULD HAVE PREVENTED THIS INCIDENT. SUPPLEMENTAL INFO FROM ACN 318663: THE ACFT WOULD HAVE CONTINUED BACKWARDS IF I HAD NOT APPLIED THE BRAKES TO STOP IT FROM ROLLING FURTHER. PARKING BRAKE IN ACFT WAS OFF, NO SIGNAL WAS GIVEN THAT THE CHOCKS HAD BEEN REMOVED.
