Overwing Flex Tee

[Lescombes]

I've just been reading FAA AD-2016-04-08 which refers to "overwing flex tees" on the B788 as being principal structural elements, the failure of which may reduce the wing's ability to sustain limit load.

What's an overwing flex tee? Is it a common feature on BCA wings? Or is it something that's unique to the composite B787?

I think its "unique" to the B787 ... I think they're related to the "side-of-body" failure they had in test.

another day in paradise, or is paradise one day closer ?
