Design
The Citabria traces its lineage back to the Champ. The most noticeable external changes to the design are the Citabria's squared-off rudder surface, wing tips, and rear windows. Like the Champ, the Citabria features tandem seating. The fuselage and tail surfaces are constructed of welded metal tubing. The outer shape of the fuselage is created by a combination of wooden formers and longerons, covered with fabric. The cross-section of the metal fuselage truss is triangular, a design feature which can be traced all the way back to the earliest Aeronca C-2 design of the late 1920s.
The strut-braced wings of the Citabria are, like the fuselage and tail surfaces, fabric covered, utilizing aluminum ribs. Most Citabrias were built with wooden spars. American Champion has been using aluminum spars in the aircraft it has produced and has, as well, made the aluminum-spar wings available for retrofit installation on older aircraft.
The landing gear of the Citabria is in a conventional arrangement. The main gear legs of most Citabrias are made of spring steel, though American Champion began to use aluminum gear legs in 2004. Early Citabrias were fitted with steel tube main gear which use an oleo strut for shock absorption. All of the variants are discussed in more detail below.

Famous quotes containing the word design:
“If I knew for a certainty that a man was coming to my house with the conscious design of doing me good, I should run for my life ... for fear that I should get some of his good done to me,—some of its virus mingled with my blood.”
—Henry David Thoreau (1817–1862)
“Nowadays the host does not admit you to his hearth, but has got the mason to build one for yourself somewhere in his alley, and hospitality is the art of keeping you at the greatest distance. There is as much secrecy about the cooking as if he had a design to poison you.”
—Henry David Thoreau (1817–1862)
“Teaching is the perpetual end and office of all things. Teaching, instruction is the main design that shines through the sky and earth.”
—Ralph Waldo Emerson (1803–1882)
