Deviation from tri-bi-maximal (TBM) mixing is an important topic in the recent neutrino physics. In this paper we try to get non- zero Ue3 without disturbing the atmospheric and solar mixing angles. Present analysis is in case of inverted and normal hierarchical mass models using the charge lepton correction in the PMNS (Pontecorvo-Maki-Nakagawa-Sakata) matrix without CP violating phase. Here we have shown that in this case one can perturb the TBM condition in order to generate a seizable value of Ue3 in the range of 0.6 to 0.8, while at the same time keeping solar neutrino mixing near its measured value, which is close to and the atmosphere neutrino mixing close to sin2θ12 = 1/3 and the atmosphere neutrino mixing close to sin2θ23 = 1/2.
