Magnetohydrodynamic (MHD) stability of an axisymmetric mirror device with long end-sections filled with a collisional plasma is studied. It is shown that unstable perturbations in such a system, if they exist, are localized at a distance {approximately}{ital v}{sub {ital A}}/{Gamma} near the central cell ({ital v}{sub {ital A}} is the Alfv{acute e}n velocity and {Gamma} is the growth rate). Perturbations of the magnetic field do not penetrate into regions where plasma beta is greater than unity. Therefore, regions of weak magnetic field has a stabilizing effect on MHD-perturbations. {copyright} {ital 1996 American Institute of Physics.}
