We have calculated the pole part of the one-loop graviton self-energy in the noncovariant axial gauge n/sub ..mu../phi/sub munu/ = 0, n/sup 2/not =0, where phi/sub munu/ is the physical graviton field and n/sub ..mu../ is an arbitrary but constant vector. It is shown that the self-energy is, unexpectedly, both nontransverse and n/sub ..mu../ dependent, even though it satisfies the correct gravitational Ward identity. This Ward identity is found to contain a term corresponding to a ''pincer'' Feynman diagram which is directly responsible for the nontransversality of the graviton self-energy. Ghost particles do not contribute to the graviton amplitude. All axial-gauge integrals are consistently evaluated in the context of dimensional regularization and by applying the principal-value prescription.
