The major aircraft structures are wings, fuselage, and empennage. The primary flight controls are ailerons, elevators, and rudder, located on the surfaces, wings, and vein. These parts are connected by seams, called joints.
All aircraft wing joints manufactured using rivets, bolts or special fasteners having lap joints. Fasteners may not be used on joints that do not overlap material for joining – for example, butt, tee, and edge joints. A faded edge is a type of lap joint when two metal surfaces overlap against each other in such away.

Internal aircraft parts are manufactured in four ways: milling, stamping, bending, and extrusion. The metal of a milled part is changed from cast to wood by first shaping and then chemically etching or grinding. A stamped part is announced, placed in a forming press, and then heat-treated again.
Bent parts are made by sheet metal mechanics using bend allowance and layout procedures. An extrusion is an aircraft part made by forcing metal through a predetermined die. The wings of the aircraft have to be significantly stronger than the positive forces of flight as well as the negative forces of landing.
There are two types of metal wings: semicolon and full cantilever. Semiconductor, or braided, wings are used on light planes. They are externally supported by struts or flying wires that connect the wing spur to the fuselage. A full cantilever wing is usually made of strong metal.
Two or more spores are used in the construction of a wing. They carry the main longitudinal-fetish to load the wing. Both the spar and a compression rib attach the wing to the fuselage.
