Narrative:
During final taxi to our assigned gate, our aircraft nosewheel rolled into the ground chocks. The aircraft chocks were posed right on the lead-in lines to the gate. The gate area was congested and required our strict attention to wing tips and ground personnel signals. Just prior to rolling into the chocks, ground personnel gave a stop signal. The signal was received too late and the aircraft rolled into the chocks. A good attempt by the captain to stop was made. Due to the tight turn required to follow the lead-in lines, I could not see over the nose of the aircraft to see the chocks. The captain indicated the same. After hitting the chocks, the nosewheel locked into the 90 degree position. The aircraft was left stopped just short of the jetway. All passenger were deplaned normally by portable stairs. No injuries to passenger or damage to aircraft were incurred. Maintenance unlocked the nosewheel and performed a check of the system. Once again, no damage and we were underway in short order. Either lack of training or poor judgement contributed to this occurrence. The chocks should never be in the taxi path of the aircraft and a stop signal should be given far in advance to allow the captain to have enough time to stop.

Title: ACR MLG SUFFERS TEMPORARY ACFT IMMOBILIZATION IN RAMP OP ACFT PARKING PROC.
Narrative: DURING FINAL TAXI TO OUR ASSIGNED GATE, OUR ACFT NOSEWHEEL ROLLED INTO THE GND CHOCKS. THE ACFT CHOCKS WERE POSED RIGHT ON THE LEAD-IN LINES TO THE GATE. THE GATE AREA WAS CONGESTED AND REQUIRED OUR STRICT ATTN TO WING TIPS AND GND PERSONNEL SIGNALS. JUST PRIOR TO ROLLING INTO THE CHOCKS, GND PERSONNEL GAVE A STOP SIGNAL. THE SIGNAL WAS RECEIVED TOO LATE AND THE ACFT ROLLED INTO THE CHOCKS. A GOOD ATTEMPT BY THE CAPT TO STOP WAS MADE. DUE TO THE TIGHT TURN REQUIRED TO FOLLOW THE LEAD-IN LINES, I COULD NOT SEE OVER THE NOSE OF THE ACFT TO SEE THE CHOCKS. THE CAPT INDICATED THE SAME. AFTER HITTING THE CHOCKS, THE NOSEWHEEL LOCKED INTO THE 90 DEG POS. THE ACFT WAS LEFT STOPPED JUST SHORT OF THE JETWAY. ALL PAX WERE DEPLANED NORMALLY BY PORTABLE STAIRS. NO INJURIES TO PAX OR DAMAGE TO ACFT WERE INCURRED. MAINT UNLOCKED THE NOSEWHEEL AND PERFORMED A CHK OF THE SYS. ONCE AGAIN, NO DAMAGE AND WE WERE UNDERWAY IN SHORT ORDER. EITHER LACK OF TRAINING OR POOR JUDGEMENT CONTRIBUTED TO THIS OCCURRENCE. THE CHOCKS SHOULD NEVER BE IN THE TAXI PATH OF THE ACFT AND A STOP SIGNAL SHOULD BE GIVEN FAR IN ADVANCE TO ALLOW THE CAPT TO HAVE ENOUGH TIME TO STOP.
