Having seen some of these Haaj operators at work first hand I wouldn't be surprised if the aircraft in question was significantly over it's max weights and there were more bums than seats on board.
That being said the gear shouldn't have collapsed on the ground, it's designed to absorb touchdown G forces that would be equivilent to it being over twice the max landing weight which I'm sure it wasn't.
At least the evacuation meant none of the pax got round to lighting their gas stoves for cooking lunch. You think I'm kidding?
