On tues eve an united crj-7,9 not sure what model, suffered aircraft dammage due to new jetways installed with ground power unit. after the aircraft was offloaded and grommed for the eve, an employee pulled the jetway away from aircraft whille g.p.u. was still attached. there was noticeable dammage to nose gear doors. and the ground power was ripped off from bridge, will this aircraft be grounded for a while or will they just do a temp fix job and ferry it back to the usa.

Who is the manufacturer of the new loading bridges at YYC. For the new loading bridges at YOW, which were built by Dew Engineering, it is impossible to move the bridge if the GPU is attached to the aircraft. I'm surprised YYC's bridges don't have the same safety feature.

Ok, the aircraft involved was in fact in new colors (I saw the damaged aircraft up close and personal).
Im not sure of the manufacturer of the bridges, however the GPU cord is lowered down from these bridges using a cable hoist system. If the cable hoist is down even a inch, the bridge cannot be moved with the execption of the auto-leveling system which adjusts the bridge height acording to the movements of the aircraft during loading and unloading. The cable is easily removed from the hoist using 2 standard carabeener clips. The ground power cord does not need to be attached to the hoist for the hoist to go up or down.
It was my assumtion that the aircraft was a RON flight. And this had happened shortly before departure in the morning.
What probally had happened, is Air Canada (united's ramp contractor in Calgary) had lowered the hoist and ground power and then detached the GPU from the clips on the hoist, and the hoist was put back up. The aircraft arrived GPU was plugged in for the evening. The next morning with the hoist still being in the up position the CSA moved the bridge back for departure and you know what happens next. However I can tell you these ground power cables are half decently long, and the only was for this to happen was the bridge must have been moving all the way back to the home position, which on gate 31(where the accident occured) is a good 70+ feet back from the CRJ hash mark.
I have a feeling this is just due to the fact that Air Canada rarely ever uses these more modern bridges. In fact its the second time I have ever seen them using gates C/D 31-34.
Here at Westjet we have strict policys on having the hoist down a inch or so when ever the ground power is not clipped to the hoist and GPU plugged in to the aircraft.

My bad . The old colours UA CRJ at at Amax must have been there for an inspection. There is presently a new colours CRJ at the Avmax hangar (regn N7155K I think,it's dark ! ) .The acft's nose is in the hangar.
