Results of the first pion single-charge-exchange experiment on a polarized nuclear target are reported. Analyzing powers {ital A}{sub {ital y}} for the ({pi}{sup +},{pi}{sup 0}) reaction at {ital T}{sub {pi}}{sup +}=163 MeV on a polarized {sup 13}C target were measured over an angular range between 20{degree} and 60{degree} in the laboratory system. Calculations in the distorted-wave impulse approximation do not reproduce these new data.
