Abstract
A twisted covariant formulation of noncommutative self-dual gravity is presented. The formulation for constructing twisted noncommutative Yang-Mills theories is used. It is shown that the noncommutative torsion is solved at any order of the -expansion in terms of the tetrad and some extra fields of the theory. In the process the first order expansion in for the Pleba\'nski action is explicitly obtained.
