In this paper we show that every class A operator has a scalar extension.
In particular, we get that such operators with rich spectra have nontrivial
invariant subspaces. Also we give some spectral properties of the scalar
extension of a class A operator. Finally, we show that every class A operator
is nonhypertransitive.
