The validity of the transport approximation is checked for systems which cannot be treated by the diffusion approximation and deviations of the transport approximation from exact calculations are evaluated by means of a perturbation formula. It is concluded that even for critical systems of dimensions of the order of the transport mean free path the transport approximation yields good results.
