GENERAL.
This chapter explains the removal and installation procedures for the wings and related components from the
aircraft.
DESCRIPTION.
Each wing panel is an all metal, full cantilever, semi-monocoque type structure with removable tips and access
panels. Attached to each wing are the aileron, flap, main landing gear and powerplant. Installed in each engine
nacelle is a bladder type fuel tank with a capacity of 54 U.S. gallons each or a total capacity of 108 U.S. gallons.
The wings are attached to each side of the fuselage by inserting the butt ends of the main spars into a spar box
carry through. The spar box is an integral part of the fuselage structure which provides, in effect, a continuous
main spar with splices at each side of the fuselage. There are also fore and aft attachments at the front and rear
spars.
The major subassemblies of the wing may be removed individually or the wing may
be removed as a unit. To remove a wing, a fuselage and wing supporting cradle is
required
AUXILIARY STRUCTURE.
WING TIP.
REMOVAL OF WING TIP.
1. Remove the screws holding the wing tip to the wing being careful not to damage the wing or wing tip.
2. Pull off the wing tip far enough to disconnect the navigation light wire assembly. The ground lead may be
disconnected at the point of connection on the wing rib and the positive lead may be disconnected at the
wire terminal or unscrewed from the light assembly.
3. Inspect the fiberglass wing tip to ascertain that it is free of cracks, severe nicks and minor damage.
REPAIR OF WING TIP.
Fiberglass wing tips may be repaired in accordance with fiberglass repair procedures in the structural repairs
portion of Chapter 51. Badly damaged thermoplastic tips should be replaced.
INSTALLATION OF WING TIP.
1. Place the wing tip in a position that the navigation light leads may be connected. Connect the ground lead
to the wing rib by use of a screw and nut and the positive lead to the navigation light by connecting the wire
terminals or screwing the connectors together. Insulate the wire terminals and be certain that the ground
lead is free of dirt and film to insure a good connection.
2. Insert the wing tip into position and install the screws around the tip. Use caution to refrain from damaging
the wing tip or wing. Check operation of the navigation light.
