There has been a heap written on this subject before and I'm sure you're going to get some great answers here too but I would preface by comparing it's overall accident rate to other aircraft.
Also consider the nature of the hours flown by this particular workhorse machine. 4 different 210s I flew have been destroyed...none of them happened because it was a 210.
(It has one of the strongest wings but ADs need to be carried out to ensure it stays that way)
