The scattering lengths and s-wave phase shifts for ..pi..d elastic scattering are calculated in the framework of an isotopically noninvariant approach that takes into account the mass splitting of the pionic and nucleonic isomultiplets. It is shown that the particle mass differences lead to appearance of the imaginary parts in the ..pi..d scattering lengths (approx.10/sup -4/ fm) not associated with pion absorption. The sensitivity of the mass-difference effects to variation of the parameters of the ..pi..N potential is studied and turns out to be small.
