Malcolm, I think you know that the Sioux City accident was not due to
a fan-blade failure.  It was due to a rotor-disk failure.  All engines
do have to go through a fan-blade-failure test just like they have to
go through birdstrike tests (but not a rotor-disk-failure test).  In
most cases, a fan-blade failure should not cause a catastrophic failure
of the engine.
