Bilinear R-parity violation (BRPV) provides the simplest intrinsically
supersymmetric neutrino mass generation scheme. While neutrino mixing
parameters can be probed in high energy accelerators, they are unfortunately
not predicted by the theory. Here we propose a model based on the discrete
flavor symmetry $A_4$ with a single R-parity violating parameter, leading to
maximal atmospheric mixing and a small but nonzero reactor angle, in agreement
with experiment.
