You forgot to retract the landing lights. I bet the vibration stops then.
Yeah, they do produce a lot of turbulence, (A319/A320/A321 series only - they're extendable to VMO if I recall) and resulting vibration but it is not at all the same as the airframe vibration I experienced.
As I described, there was a definite cycling, 6 - 8Hz, felt through the airplane and control pedestal, and I saw the horizontal stabilizers moving.
red 5 describes the problem and solution very well.
Whether fatigue life is an issue or not is an engineering problem but instinctively I don't think anyone here believes that flutter is a good thing for an airframe.
This issue will undoubtedly be part of the AAIU investigation into the aileron-casting failure on an
AerLingus A330.
