Narrative:

Having started both engines and completing the 'after start' checklist, I signaled for chock removal. I will emphasize that I was applying pressure on the brakes during the start and at all times following the start. I watched the ramper acknowledge my signal and move towards the airplane to remove the chocks. My attention was divided between the inside of the cockpit and looking outside. It was apparent that the ramper was having difficulty removing the chocks. It felt as though he were kicking them to dislodge them. I felt 3 bumps. When I looked toward the ramper to ensure that he had removed the chocks, he signaled to shut down the engines. I did so, using normal procedures. I then opened the door to let myself out of the airplane. At that time, I saw one of our ramp pickups under the nose of our aircraft. The airplane had rolled a few (4) feet when the lodged chock was removed. It was not noticeable in the cockpit. The pick-up had been driven in front of the airplane after I signaled for chock removal. Neither my first officer nor I saw it. When it stopped in front of the aircraft it was so close it could not be seen from the cockpit. When we bumped into the pick-up, it felt like the third kick on the chock. Our company policy is to not set the parking brake. Application of the brakes did not prevent the aircraft from moving forward. Supplemental information from acn 129290: the signalman should always be visible to the captain with someone else pulling the chocks and a signal should be given to the captain to reconfirm that the brakes are set before the chocks are removed.

I WILL EMPHASIZE THAT I WAS APPLYING PRESSURE ON THE BRAKES DURING THE START AND AT ALL TIMES FOLLOWING THE START. I WATCHED THE RAMPER ACKNOWLEDGE MY SIGNAL AND MOVE TOWARDS THE AIRPLANE TO REMOVE THE CHOCKS. MY ATTN WAS DIVIDED BETWEEN THE INSIDE OF THE COCKPIT AND LOOKING OUTSIDE.

THE PICK-UP HAD BEEN DRIVEN IN FRONT OF THE AIRPLANE AFTER I SIGNALED FOR CHOCK REMOVAL. NEITHER MY F/O NOR I SAW IT.
