I don't have any personally but I have a friend that has had
three
in
3500hrs. One connecting rod failure in a 210. A crankshaft
failure
in
an
Azetec and I forget the details of the third failure. It has
been
estimated
that 10% of Malibus have had inflight engine failures of some
kind.


It'd be interesting to know the maintenance history of those birds
that
did
have failures (skimped maintenance, etc).

It's also be interesting to know the total operating hours of the
Malibu
fleet, Lycoming vs. Continental...
