  Some phenomenological aspects of a supersymmetric model for fermion mass
hierarchy proposed previously are discussed. It is required that the lepton
universality violation is near to its current experimental bound. The lepton
number violation decay modes $\tau \to 2e\mu$ and $3\mu$ maybe observable in
the near future. The Majorana mass of electron-neutrino is predicted to be
about 0.1 eV. The fine-tuning problem is discussed.
