Great.
Whatever happened to the old "Out of an abundance of caution" schtick they use when going after lawful gun owners when some nutcase shoots up a school? This is the second explosion of this type of engine, on this type of aircraft, operated by this particular airline, within two years. They got lucky with the first one. This time one person died. How many deaths will be necessary before we progress to recognizing a hazard?
It's a matter of scale. The amount of successful, problem free hours on this engine is staggering, both with and without considering a single airline.
And there WILL be an inspection requirement, so it's not like theyre doing nothing. Until a metallurgical analysis indicates why the thing failed, there's no benefit to pulling them all or stopping their flights. So, if the ultrasonic inspections of the rest of the fleet reveal a systemic problem, that'll allow them to narrow it down even more. Potentially to the foundry that made the metal.
They don't know what happened yet. It could have been a piece of loose sheet metal patching on something else that got sucked into it. there's a million probable causes.
There's so much documentation on these engines , the origin of every piece is known. With only two engines failing, they have to narrow it down more before they'll be able to say "all engines from XYZ factory with blades produced between XYZ and XYZ, with aluminum from ABC Corporation, need new fans asap"
They're
