  Motivated by the recent Super-Kamiokande results on atmospheric neutrinos, we
incorporate massive neutrinos, with large angle oscillation between the second
and third generations, in a scenario with R-parity violating supersymmetry. We
emphasize the testability of such models through the observation of comparable
numbers of muons and taus, produced together with the W-boson, in decays of the
lightest neutralino. A distinctly measurable decay gap is another remarkable
feature of such a scenario.
