The availability of polarized nuclear targets for nuclear reaction studies offers new research directions. In this paper we present the distorted wave impulse approximation formalism and calculations for two-nucleon pion absorption on polarized nuclear targets. We assume that the pion absorbs on a {sup 3}{ital S}{sub 1} {ital n}-{ital p} pair and use phenomenological amplitudes to describe the {pi}{ital NN} vertex. The effects of the distortions on the incoming pion and outgoing protons, in contrast to the elementary {pi}{ital NN} vertex, are delineated for certain special cases in which the formalism simplifies. Predictions of cross sections and vector and tensor analyzing powers are made for polarized target nuclei {sup 6}Li, {sup 7}Li, {sup 13}C, and {sup 14}N at pion incident energies of 115, 165, and 255 MeV.
