Narrative:

Without asking crew, ground personnel removed chocks from aircraft. Aircraft rolled back approximately 10-20 ft shearing stair truck side panel off. Pilots not in seats at time of movement. First officer ran to flight deck and set brakes. No damage to aircraft and no injuries to persons on ground. No passenger on aircraft at time of incident. L1 door on aircraft checked by maintenance, found safe for flight. Aircraft scheduled ferry to jfk ok. Entry made in aircraft log to recheck door on arrival jfk, found ok. Ground personnel are less qualified to work on or near aircraft. This has become a real problem in the last few yrs. FAA should check training and qualification of all ground handlers. We get a lot of damage and many are hurt. The side of the stair truck that fell to ground is several hundred pounds and if it hit someone it would be fatal. Also our aircraft B757 would have rolled into the water at edge of airport if crew had not applied brakes. Chocks are installed at shutdown and brakes released as normal operating procedures. Aircraft was on the ground approximately 30 min when chocks removed with no warning.

Original NASA ASRS Text

Title: GND CREW PULLED WHEEL CHOCKS CAUSING THE ACFT TO ROLL BACK HITTING THE AIRSTAIR WITH THE ACFT CABIN DOOR BREAKING OFF 1 OF THE AIRSTAIR PANELS.

Narrative: WITHOUT ASKING CREW, GND PERSONNEL REMOVED CHOCKS FROM ACFT. ACFT ROLLED BACK APPROX 10-20 FT SHEARING STAIR TRUCK SIDE PANEL OFF. PLTS NOT IN SEATS AT TIME OF MOVEMENT. FO RAN TO FLT DECK AND SET BRAKES. NO DAMAGE TO ACFT AND NO INJURIES TO PERSONS ON GND. NO PAX ON ACFT AT TIME OF INCIDENT. L1 DOOR ON ACFT CHKED BY MAINT, FOUND SAFE FOR FLT. ACFT SCHEDULED FERRY TO JFK OK. ENTRY MADE IN ACFT LOG TO RECHECK DOOR ON ARR JFK, FOUND OK. GND PERSONNEL ARE LESS QUALIFIED TO WORK ON OR NEAR ACFT. THIS HAS BECOME A REAL PROB IN THE LAST FEW YRS. FAA SHOULD CHK TRAINING AND QUALIFICATION OF ALL GND HANDLERS. WE GET A LOT OF DAMAGE AND MANY ARE HURT. THE SIDE OF THE STAIR TRUCK THAT FELL TO GND IS SEVERAL HUNDRED LBS AND IF IT HIT SOMEONE IT WOULD BE FATAL. ALSO OUR ACFT B757 WOULD HAVE ROLLED INTO THE WATER AT EDGE OF ARPT IF CREW HAD NOT APPLIED BRAKES. CHOCKS ARE INSTALLED AT SHUTDOWN AND BRAKES RELEASED AS NORMAL OPERATING PROCS. ACFT WAS ON THE GND APPROX 30 MIN WHEN CHOCKS REMOVED WITH NO WARNING.
