Metal Spar Wing Information


Traditionally the Champion line of aircraft used wooden wing spars nailed to aluminum ribs as the primary wing structure.  This changed in 1990 when American Champion Aircraft redesigned and certified this structure with aluminum spars.   This change is the core difference between new aircraft and older models (1980 and older).   In fact, American Champion has never offered a wood spar wing.  The metal spar wings can retrofit to any of the older Citabria line and offer an affordable alternative (and upgrade) to rebuilding an old pair of wings.

Why metal spar wings? For one, you don't see the rest of industry using wood spars. With the redesign, certain engineering aspects could be taken into account to improve performance and reliability.  The metal wing assemblies act more as an upgrade than a replacement, offering numerous advantages to the owner.
