Milo??? It's a wing for goodness sake.
Take a good look at the curvature of the leading edge. Now look at the curvature of the leading edge of the known stabilizer.....see any difference?
That section of the wing is the bottom side, looking at the junction between the aileron and the outboard flap (which appears to be missing).
Simply put, there are no 4x6 inch (wide open no doubt) access holes in the leading edge of any wing, unless there is a slat placed purposefully in front of them.
With what we know now....The last moments of 5022 were spent trying to stop....and selecting flaps/slats would not be the smartest way to get the most weight on the wheels. I think very much that these wings were correctly configured for TO.
