Surely there's no chance a windmilling engine would create severe vibration like that
What ever is causing the vibration would stop the windmill one would've thought
WRONG - A few years back an EK A330 suffered an engine failure (main fan blade separation during the climb at about 35000 ft) during departure from Lusaka, The crew shut it down, but the vibrations from the windmilling donk were so severe that the Captain told me he couldn't read any instrumentation, and thought that the engine would separate. They had 3 pilots on the sector and the augmenting FO had to do the landing performance calcs on the portable laptop, as the touch screen fixed EFB's were unusable. He said the vibrations only receded to comfortable levels when that slowed down with flap 2.
