Abstract: Let $ X$ be a second countable, locally compact Hausdorff space, and let a compact Lie group $ D$ act on a $ {{\text{C}}^ * }$-bundle $ (E,X)$, the fibres of which are of bounded, finite dimension. Denote by $ A$ the $ {{\text{C}}^ * }$-algebra of sections vanishing at infinity, and by $ \hat \alpha $ the induced action of $ D$ on $ A$. The stable ranks of both, the fixed point algebra $ {A^{\hat \alpha }}$ and the crossed product algebra $ A{ \times _{\hat \alpha }}D$ are determined.
