  We propose a new $A_4$ model in which both the right-handed neutrinos and
right-handed charged leptons transform as $A_4$ singlets. We reproduce
tri-bimaximal mixing pattern exactly although the $A_4$ symmetry is broken
completely at leading order in both the neutrino and charged lepton sectors.
The charged lepton mass hierarchies are controlled by the spontaneous breaking
of the flavor symmetry. The light neutrino spectrum is predicted to be of
normal type and the lightest neutrino is massless at leading order. Although
the reactor angle $\theta_{13}$ is expected to be of order $\lambda^2_c$ from
the next to leading order corrections, this model cannot be ruled out by
current experimental data including the latest T2K results. Leptogenesis is
realized via the resonant leptogenesis of the second and the third heavy
right-handed neutrinos which are degenerate at leading order. The
phenomenological consequences for lepton flavor violation are discussed in
detail.
