I wonder if they are waiting for some specialist parts for the air-bridge? It would seem to be a highly unusual situation for the floor of the thing to collapse, so it might be that parts which are not usually required to be replace ever need to be installed. There could be a significant lead time on this? I cant imagine there are too many stocks of air-bridge parts in Ireland, or even the UK?
The other thought I had is that the contractors who installed it are delaying paying for the fix, you know what builders are like to come back and fix anything!
