When a twisted $CP^3$ X supports a smooth $S^1 (orT^2 )$ action, the normal representations at the fixed point set and the first Pontrjagin class of X are investigated. In the case of a $T^2$-action, we can determine them almost completely. Here we say that X is a twisted $CP^3$ if X is a closed smooth manifold such that $H*(X;Z)$ is isomorphic to $H*(CP^3 ;Z)$ additively and that the cup product $x^3$ of a generator x of $H^2 (X;Z)$ is non-zero.
