Within the limits of analytical asymptotic approach by incomplete decomposition on small parame- ters: in the first order on amplitude of oscillations and in the second order on amplitude of spheroidal defor- mation, dispersion equation for capillary oscillation of charged spheroidal drop was found. It is shown that critical conditions of electrostatic instability for all modes of a drop oscillation decrease with increase of spheroidal deformation range.
