Pion scattering from $sup 3$He and $sup 4$He is examined using a lowest order theoretical optical potential including spin. The goal is to determine the properties of these nuclei to which pion scattering is sensitive. A realistic description of the nuclear ground state that incorporates the experimental trinucleon charge and magnetic form factors and incorporates the experimental trinucleon charge and magnetic form factors and the theoretical classification of the trinucleon wave function is employed, in addition to a description of the off- shell $pi$N transition matrix based on a finite-ranged potential model and an improved pi-nucleus angle transformation. The $sup 4$He calculations establish the practical validity of the optical potential and the $sup 3$He calculations indicate the direction for future experiments and improvements in the theory. It is proposed that $pi$$sup -3$He scattering can provide information on the magnetic moment form factor of $sup 3$He.
