the two motors and the main gear box) and the four
Not shown are the flexible
shafts (several meters long) between the main gear box

Because the landing flap
panels have a trapezoidal shape and the Fowler travel is

slightly longer spindles the other parts could remain
identical. Only the left-hand and right-hand style of the
actuator housing was necessary.
