An actuation mechanism includes a control surface having a hinged end pivotally coupled to a wing structure, a first pivot arm and a second pivot arm coupled to the control surface, a first drive rod coupled to the first pivot arm, and a second drive rod coupled to the second pivot arm. A first bell crank is coupled via a first pivot pin to the wing structure at a first position and to the first drive rod. A second bell crank is coupled via a second pivot pin to the wing structure at a second position spaced apart from the first position and to the second drive rod. A coupling rod extends between the first bell crank and the second bell crank such that a rotation of the first bell crank is synchronized with a rotation of the second bell crank.
