Hot brakes on the run out resulting in a fire on the main gear... fire was reported by another a/c, A300 made uneventful emergency landing and blocked a taxiway for a while, on landing total of x2 tires totally gone and damage to the rest and the brake units - obviously. Some internal damage to flap runners due to debris from the gear didn't help things much either... A/C was serviceable again within 36hrs.
