  We present a discussion of the |Delta I|=3/2 amplitudes of the hyperon decays
B->B'+pi in the context of chiral perturbation theory. We evaluate the
theoretical uncertainty of the lowest-order predictions by calculating the
leading non-analytic corrections. We find that the corrections to the
lowest-order predictions are within the expectations of naive power-counting
and, therefore, that this picture can be examined more quantitatively with
improved measurements.
