GENERAL
This chapter describes removal, installation, and specific repair procedures for the wings and component
parts. The overall structure of the airplane and general repair procedures are described in Chapter 51.
NOTE: When torquing structural assemblies, use standard torque values as found in 91-10-00, unless
otherwise stated in this chapter.
1. Description
Each wing is an all-metal, full cantilever semi-monocoque type construction with a removable
thermoplastic tip. Installed in each wing ahead of the main spar is a metal fuel tank with a capacity of 25
U.S. gallons each or 50 U.S. gallons total. Attached to each wing is an aileron, flap and main landing
gear. 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
attachment points at the front and rear spars.
NOTE: 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 supporting cradle is required.
NO
TE: The Warrior III Parts Catalog, P/N 761-897, provides detailed views of the individual structural
components.
All exterior surfaces are coated with enamel or acrylic lacquer. As an option the airplane may be
completely primed with zinc chromate or equivalent.
2. Repairs
Structural repairs must be made in accordance with the guidance provided in FAA Advisory Circular
43.13-1. To assist in making repairs and/or replacements, Figure 1, 51-70-00, identifies the type and
thickness of various skin materials used. Never make a skin replacement or patch plate from material
other than the type of the original skin, or of a different thickness than the original skin. The repair must
be as strong as the original skin. However, flexibility must be retained so the surrounding areas will not
receive extra stress.
