AUXILIARY STRUCTURE - DESCRIPTION AND OPERATION
1. General
A. The auxiliary structure consists of those structural wing components which are outside the main frame. Therefore the auxiliary structures are the leading edge, the trailing edge, the wing tip and the flight controls. The structural composition of the flight controls is described in 57-50-0.
2. Leading Edge Structure
A. The leading edge structure (figure 1) in the area of the flaps consists generally of a series of flanged ribs attached to the upper forward face of the wing front spar, each rib being additionally supported by a short tubular brace between the lower side of its forward end and the lower forward face of the wing front spar. The upper edges of the ribs carry the leading edge skin. The flap hinges are attached to the forward ends of the ribs.
B. The leading edge structure (figure 2) in the area of the slats consists of slat guides and actuators supported between pairs of flanged ribs mounted on the forward face of the wing front spar web.
3. Trailing Edge Structure
A. The trailing edge structure consists of brackets and stiffeners cantilevered aft of the wing rear spar. Certain of the brackets within this structure serve to support the hinge fittings for the ailerons.
B. The tracks carrying the inboard and outboard trailing edge flaps are described in 57-42-0.
C. The spoilers are supported by brackets extending aft from the aft faces of the rear spar and the landing gear support beam.
4. Wing Tip Structure
A. The left and right wing tips are similar in structure. The wing tip consists of the structure outboard from the tank end rib and outboard from the leading edge and the aileron. (See figure 3.)
