    We study the effects of neutrino spin-flips in the magnetic field, BAGN, of an active galactic nuclei (AGN) for high-energy neutrinos (E greater than or equal to 10(6) GeV) originating from the AGN, induced by an interplay of a violation of the equivalence principle parameterized by Deltaf and the twist in B-AGN. We point out that a conversion effect may exist for Deltaf similar to 10(-34)(deltam(2)/10(-5) eV(2)) independent of the gravity mixing angle. Observational consequences for this conversion effect are discussed.
