We revisit the Fritzsch-type lepton mass matrix models confronted with new experiments for neutrino mixings. It is shown that the model is viable and leads to a rather narrow range of free parameters. Using empirical mixing information between νe and νμ, and between νμ and ντ, it is predicted that the mixing angle between nue and ντ is in the range 0.04<|U13|<0.20, consistent with the CHOOZ experiment and the lightest neutrino mass is 0.0004<m1<0.0030 eV. The range of the effective mass measured in double beta decay is 0.002<< mee><0.007 eV.
