Abstract A model for extragalactic jets considered as magnetized current-carrying structures is presented. The return currents are assumed to flow within the jet itself. Standard MHD equations in cylindrical geometry are used to investigate the equilibrium and stability properties of the model, including the incompressible thermal matter flows in the equilibrium analysis. Absolute stability regions are found and their boundaries are determined. Linear growth rates for the unstable m = 0 and m = 1 modes are computed.
