ACTION: Final Rule.

SUMMARY:  This AD was prompted by fatigue cracks initiating in the flap support structure due to repetitive flap loads, which has caused flap nose roller support bracket failure.

This AD requires replacement of the flap nose roller fitting, nose roller support bracket, and adjacent rib support structure with improved components.
