CARJ IS DAMAGED WHEN CAPT RELEASES BRAKES ASSUMING GND CREW HAD INSTALLED WHEEL CHOCKS.

Narrative

UPON PARKING AT AVL THE MARSHALLER GAVE ME THE SIGNAL TO STOP. I STOPPED THE ACFT AND SET THE BRAKE. THE MARSHALLER WALKED FORWARD TOWARD THE ACFT AND WENT OUT OF MY SIGHT. SINCE THE CHOCKS WERE NEXT TO THE ACFT PARKING SPOT; I ASSUMED HE WAS CHOCKING THE ACFT. I DID NOT GET THE SIGNAL THAT THE ACFT WAS CHOCKED NOR DID I SEE THE MARSHALLER AGAIN. I ASSUMED (HA HA) THE ACFT WAS CHOCKED. I READ THE CHKLIST AND RELEASED THE BRAKES. SOMEONE YELLED THAT THE ACFT WAS MOVING SO I APPLIED THE BRAKES. THERE WAS A SLIGHT THUD AND I THOUGHT THE ACFT NOSE TIRE HIT THE CHOCK. I WAS THEN INFORMED THAT THE WING FLAP WAS DAMAGED BECAUSE WE HIT THE BAGGAGE LOADING CART. THE MAIN CABIN DOOR WAS OPEN AND THE PEOPLE WERE UP. I DO NOT KNOW IF THERE WERE PEOPLE ON THE STAIRS AT THE TIME. IT IS VERY CLR TO ME NOW THAT THE CHOCKS WERE NOT IN. THE STATION MGR INFORMED ME THAT THE 3 FORWARD GND PERSONNEL THOUGHT THE OTHER ONE HAD SET THE CHOCKS. I ALSO DISCOVERED THAT WE PARK ON AN INCLINE IN AVL. I ESTIMATE WE ROLLED 3-4 FT. IT IS MY FAULT FOR NOT ENSURING THE ACFT WAS CHOCKED. I TAKE THE BLAME FOR THAT. ONE QUESTION -- WHY DID 3 GROUND RAMP PERSONNEL NOT CHOCK AN ACFT? DO THEY NOT HAVE A GAME PLAN ON WHO IS TO DO WHAT? SECOND; IF WE ARE GOING TO PARK ON SUCH A SLOPE; GIVE THE PLT SOME NOTICE. PAINT THE RAMP; HAVE THE STATION NOTIFY US; PUT SOMETHING IN THE STATION NOTES.
