  We demonstrate separability of the Dirac equation in weakly charged rotating
black hole spacetimes in all dimensions. The electromagnetic field of the black
hole is described by a test field approximation, with vector potential
proportional to the primary Killing vector field. It is shown that the
demonstrated separability can be intrinsically characterized by the existence
of a complete set of mutually commuting first order symmetry operators
generated from the principal Killing-Yano tensor. The presented results
generalize the results on integrability of charged particle motion and
separability of charged scalar field studied in [1].
