Air carrier flight crew reported the aircraft rolled into a chock during gate arrival when the brakes were not set.
Synopsis
Air carrier flight crew reported the aircraft rolled into a chock during gate arrival when the brakes were not set.
Narrative
Stuck Chock - Ground Crew Lacked HeadsetApparently during the block in during the inbound flight; the aircraft had slightly rolled causing one of the chocks to get stuck under the nose wheel. During the departure process; the ground crew did not have headsets; so we could only communicate via hand signals. We could hear the crew banging on the chock; and the ground crew repeatedly gave me the hand signal to set the brakes. I repeatedly confirmed via hand signal that the brakes were set; to which they would respond again with the brakes set hand signal. This repeated several times. The ground crew then signaled to me in such a manner that it seemed they wished for me to turn the nose wheel. I did; and they were able to remove the chock. I was informed that apparently a violation was issued by the authorities for the brake not being properly set. However the brake not being set; and the aircraft rolling on to the chock; occurred on the inbound sector; in which I was in the observers seat. But clearly there was confusion about the brakes as we were departing; however the brakes were never released during this process. If the ground crew were properly equipped; this confusion would have been avoided.
Second reporter narrative
Brakes Not Set During Arrival and Placement of ChocksI was sitting in the second observers seat. Upon block in; the PF; who was seated in the captains seat while undergoing OE (Operating Experience); apparently forgot to set the brake; which allowed the aircraft to roll slightly in to one of the chocks. This caused issues with the ground crew being unable to remove the chock during the subsequent outbound ZZZZ-ZZZ1 flight.
