It happened to me on a CX250 ex-LHR. Feb 2000.
CX250 B-HOW. The Swire Bottler was captain.
Fortunately the a/c slated to operate CX254 was ready and waiting at the hangar so the total delay was about 2 hrs.
The cause was hydraulic failure on the airbridge jacking system.
Damage to HOW was ruptured door hinges, I seem to remember that it was Door 1L but it might have been 2L.
We had the obligatory stroppy SLF who was threatening to sue CX for a contract he was about to lose by way of not making it to Seoul in time for an important meeting. As soon as it was pointed out to him that we could rebook him onto Korean Airlines (which was parked next to us) he mysteriously became all trance-like and returned to his seat like a naughty boy sent to the naughty corner!!!!!
