I think it is because it stopped the vibrations.

I believe the roesan Boeing keeps pushing out Air India 787's is because if they did not Air India would want more compensation for delays. It seems like Boeing is working hard to finish the flight tests on the aircraft as in the last week 2 became ready for delivery. I believe LAN will take delivery soon and have the delivery flight before the end of the year, now that it is ready for delivery.
