But it all still seems very subjective to me. I would hope that there is further advice that better defines the circumstances that they are describing.
Was the vibration level observed in the passenger's video "high", as envisaged by the advice from Boeing?
Or was it "extreme"and way beyond anything they ever considered? ((Not saying it was. Just asking)
And how long did they anticipate that the vibration would last or be tolerated for?
The vibration level observed in the passenger cabin was similar to other events and of little relationship to highly damped structural systems in the airframe.
As stated much earlier it is way below the expectations for continued flight in turbulence and gusting levels.
Of course some local parts (tubing, brackets, etc.) associated with the failed engine pylon need be inspected before flight.
I expect that the Australian ATSB will later report on findings.
I'm still awaiting any glimpse of overall photos of the fan as I can't see any great fan damage including the cowl
