It's just a flight to ferry the plane to its "storage" place while the grounding still takes effect.
But, there's A HUGE ELEPHANT in the room. The Max 8 engine, CFM Leap-1B, seems to have been failing in a very alarming rate lately...
Incidents of MAX 8 engines failure as compiled by AVHERALD:
Incident: Southwest B38M at Orlando on Mar 26th 2019, engine shut down in flight
Incident: TUI B38M near Chania on Jan 29th 2019, engine problem
Incident: Spicejet B38M near Varanasi on Jan 6th 2019, engine shut down in flight
Incident: Norwegian B38M near Shiraz on Dec 14th 2018, engine shut down in flight
Are these incidents are simply showing a normal "growing pain" for this new type of engine CFM Leap-1B?? Or, it shows a major problem with its reliability/durability??
