In this paper we study the nonperturbative structure of the axial current and evaluate the two-point distribution amplitudes $\int d\xi\, e^{-iq...\xi}<0|\bar{\psi}(x)\Gamma\psi(y)J_{\mu}^{5}(\xi)|0>$ in the framework of the instanton vacuum model in the leading order in $\mathcal{O}(N_{c})$. We perform a direct numerical test of the relations between the axial current and the pion distribution amplitudes, imposed by PCAC, and found excellent agreement.
