Abstract: An analytical method, which identifies the nacelle modes from the process of modifying an airplane analysis to match the airplane GVT results has been developed.It is assumed that any analytical errors solely result from the difference between the estimated and actual stiffness of the aircraft structure.

Key words: modal analysis, modul modification, modal test
