Lift Tabs Etc

some distance from the rest of the plane and the incident was caused by
severe turbulence at the time.
Does anyone have any feedback as to the failiure mode??
Was it the attachment hardware ??<

The last report I read indicated the canard departed the aircraft after
turbulence-induced flutter of an elevator. Large chunks of F22 were found
still attached to the lift tabs, So the attachment system worked.

Not so with the Airbus 300 that crashed in New York. Some theories point
to rudder flutter, which removed the vertical fin at the attach points.
There isn't a structure out there that can withstand fully divergent
flutter of a control surface.
