The instability of the axisymmetric spherical force free plasma with the parallel plasma flow to the magnetic filed is studied by using the MHD equations under the condition of incompressibility. The linear growth rate of the unstable mode with the fixed toroidal mode number n=1 is obtained and it decreases with the increase of Alfven Mach number C_A in the rage of C_A < 1 in the case of the free boundary. The non-liner numerical analysis in the free boundary case shows that the tilting mode plays a main role, and the damping rate of the original helicity and the toroidal flux decreases with the increase of C_A.
