 Wing Tip

 The wing tip is installed at Rib 27. The wingtip fence attaches to the outboard end of the wing tip.

 (3)
 Leading Edge and Leading Edge Devices

 The leading edge assembly is forward of the front-spar of the wing-box. It includes the inboard and the outboard leading-edge assemblies and the top and the bottom panels. The inboard and outboard leading-edge assemblies have their D-noses and panels installed on ribs which attach to the front spar. The hold-down devices and the rotary actuators (for Slat 1 tracks 2 and 3) are on other ribs. The leading edge devices are the five slats.

 (4)
 Leading Edge Slats

 The leading edge slats are installed on the wing as follows:
 -
Slat 1 is between RIB2 and RIB7

 -
Slat 2 is between RIB8 and RIB12

 -
Slat 3 is between RIB12 and RIB17

 -
Slat 4 is between RIB17 and RIB22

 -
Slat 5 is between RIB22 and RIB27.

 (5) Trailing Edge and Trailing Edge Devices
 The trailing edge structure is aft of the rear spar of the wing box and includes the inner, mid and outer rear-spar trailing-edges.
 The inner rear-spar trailing-edge includes:
 -
the shroud box

 -
the overwing panel

 -
the fixed shroud

 -
the underwing panel.

 The mid and outer rear-spar trailing-edges include:
 -
the hinge ribs

 -
the intermediate ribs

 -
the actuating-cylinder brackets

 -
the top and bottom panels

 -
the trailing-edge support structures.

 The trailing edge devices are: - the two trailing edge flaps - the aileron - the five spoilers.

 (6) Trailing Edge Flaps
 The inboard and the outboard flaps are installed on the trailing edge of the wing. The inboard flap is between RIB1 and RIB9 and the outboard flap is between RIB9 and RIB22.
 (7) Aileron
 The aileron is installed on the trailing edge of the wing, between RIB22 and RIB27.
 (8) Spoilers
 There are five spoilers installed on the upper surface of each wing, forward of the trailing edge flaps. Spoiler 1 is installed between RIB5 and RIB9. Spoilers 2 thru 6 are installed between RIB10 and RIB22.
