It is provided an overview of the tetradic approach (the Palatini formalism) for gravity. It is considered some theory with new additional field B. It is shown that this model is equivalent the Einstein gravity with cosmological term and topological term in the tetradic approach. It is considered the limit of the gravitational constant G goes to 0. In the leading non-zero order of G is obtained some equation for spin connection which is equation of zero condition. It is discussed relation of this equation with MacDowell-Mansouri-Stelle-West gravity.

Keywords: tetrads, spin connections, differential forms, BF-gravity.
