How Southwest pilot Tammie Jo Shults stayed calm in the cockpit
https://www.pbs.org/newshour/show/how-southwest-pilot-tammie-jo-shults-stayed-calm-in-the-cockpit...hauntingly parallel incident that happened, same airline, same type of aircraft, same type of engine, in August of 2016.
The only difference is, nobody got hurt. The aircraft got on the ground safely, but exactly the same thing happened, with metal fatigue as the cause, and that fan blade being spit out like a hot, fast piece of shrapnel.
Subsequent to that, the manufacturer of the engine, CFM, which is a joint venture between GE and the French jet engine maker Safran, sent out a service bulletin to the airlines who had these engines and said, hey, you probably should do some ultrasound testing of these fan blades to make sure there are no cracks, because they’re not necessarily visible.
Southwest was among the airlines who resisted that call and said they just needed more time to do it and had not done those inspections.
So, the truth is, if the FAA, the NTSB had acted quicker and with more urgency after that first event in August 2016, this event might not have happened....
