Using the type II seesaw approach and properties of discrete flavor symmetrygroup representations, we build a supersymmetric $A_{4}\times A_{3}$\ neutrinomodel with $\theta_{13}\neq0$. After describing the basis of this model--whichis beyond the minimal supersymmetric Standard Model--with a superfield spectrumcontaining flavons in $A_{4}\times A_{3}$\ representations, we first generatethe tribimaximal neutrino mixing which is known to be in agreement with themixing angles $\theta_{12}$ and $\theta_{23}$. Then, we give the scalarpotential of the theory where the $A_{3}$ discrete subsymmetry is used to avoidthe so-called sequestering problem. We \textrm{next} study the deviation fromthe tribimaximal mixing matrix which is produced by perturbing the neutrinomass matrix with a nontrivial $A_{4}$ singlet. Normal and inverted masshierarchies are discussed numerically. We also study the breaking of $A_{4}$\down to $Z_{3}$\ in the charged lepton sector, and use the branching ratio ofthe decay $\tau \rightarrow \mu \mu e$--which is allowed by the residualsymmetry $Z_{3}$--to get estimations on the mass of one of the flavons and thecutoff scale $\Lambda$ of the model.
