Moderate Vibrations: Cabin Floor in A332
A friend of mine recently told me about Severe Vibrations reported by Aft Galley, (the containers were moving within the latches hard), making it impossible for the crew to work.
The FO also saw first hand the vibes.
Captain Decided that it was due to "Cabin Recirc Fans" and put them off for an hour.
Vibrations reduced, and did not recur when fans were put on.
Me thinks it could have been flutter due to high speed as well..
Advise guys..
