Happened to CX in TPE a year or so back. Airbus were informed and initially said no worries. A day or so later they changed their minds. A/C needed a new gear.
I pax in the A330 to and from Oz a lot ( i mean 15 times a year ) and I hardly ever feel a smooth landing, the first touchdown is ok, but as the gear tilt the second touchdown is a real bump.
And watching other A330 landings from the fence or whilst taxiing in I see that all A330's ( from a lot of other carriers ) do the same thing, ie nice smooth touchdown on the rear wheels, seems to hover without tilting for seconds then crunch down on the front wheels.
Give me a nice 777 any day.
