Integrability properties of $NC_{10}$-manifolds

In this paper we investigate the integrability properties of $NC_{10}$-manifolds. In particular, it is shown that the integrable $NC_{10}$-structure, and also the normal $NC_{10}$-structure, is cosymplectic. It is shown that $NC_{10}$-structure with a closed contact form is finer than cosymplectic. Local structures of investigated manifolds are given.
