because of all the cycles it has been through."

For what it is worth, the reason for the 99L crash was a catastrophic
engine failure that occurred without warning.  The engine was a stock
IO-540 that I think was purchased from Lycoming as a factory reman and
was less than a year old.  As far as I know, it would have happened in
any aircraft and had nothing to do with 99L or its state of maintenance.
It's not very common but once in a while there is an accident that has
nothing to do with pilot or maintenance error.  This was one of them.
