Flaws in jet engine fan blades like one that cracked and broke loose in April, killing a
Southwest Airlines Co. passenger, have been discovered on planes operated by several carriers, and the manufacturer is moving to further tighten inspections.
General Electric Co., part of a venture that makes the engines, found a cracked blade during post-accident inspections of another Southwest plane, and spotted four or five more in those of other airlines, Southwest Chief Operating Officer Michael Van de Ven said Thursday on a conference call to discuss earnings.
“We expect to formalize the interval in a new service bulletin that will be issued in coming days,” GE spokesman Perry Bradley said in a statement. Service bulletins are non-binding recommendations on maintenance, but are almost always made mandatory by aviation regulators.
Southwest has already cut the inspection interval for older engines almost in half, from 3,000 flights to 1,600, Chief Executive Officer Gary Kelly said in an interview.

Here's a re-creation of the event done by an Embry-Riddle prof in a CRJ sim. She demoes stickshaker, GPWS and other stuff on the single engine descent and approach.
Why is the point to use a CRJ sim? a similar failure on a CRJ you would be looking at far dearer consequences.
