Slight drift on a related topic, the one in Hong Kong a fortnight ago was a complete collapse. Caused a lot of damage to the aircraft as well. Preliminary results indicate it was caused by a modification of new/additional aircon packs being added below the aerobridge structure! A post certification add on.
There has also been a growing number of fuselage skin punctures by aerobridge canopies with protruding bolts/nuts where components of the canopy and/or rubbers have worn away and exposed the naughty bits of metal which don't play well with aircraft skins! This is a particular issue for aerodromes in locations that receive a lot of UV and harsh weather.
