NEWS from that Southwest incident that sucked a woman partly out of the plane:
The maker of the engine that blew up was getting ready to recommend inspections that would have included that engine right before the fatal accident.@AlanLevin1 https://t.co/yUz8Tqv9sq— Jennifer Jacobs (@JenniferJJacobs) April 25, 2018
In any case, inspections do not preclude the failure and it is quite possible that the vane would have shown no cracks. With a similar situation where rotorheads were cracking in the CH-46 Marine fleet, inspections were required every 10 hours. That is about every three flights. Not a very warm and fuzzy feeling on the third flight before inspection.
Protective shroud on front of engine blew off, meant to contain blade failures and came down almost intact, Witness on board flight mentioned one boom followed a few seconds later by the second and then all hell broke loose
Massive engine failure could cut controls and cause loss of ability to correct, note stains on wing from event, think A380 Quantas event that almost caused the whole plane to crash.
Coincidence?
