This paper presents the result of the normal modes analysis of N219 wing that has been done. It is done using computation method with stick model for wing structure. A short mathematical review of the normal mode analysis is presented in this paper. The analysis is done for two cases of flight, OEW and MTOW normal CG at maximum fuel. The results of analysis, natural frequencies and mode shapes, shown here, will be used for the dynamic analysis to know the flutter speed of this aircraft. The result shows that for the same frequency input of analysis, each two cases has different number of mode shapes, and different frequency in the same mode
