An analytic method from celestial mechanics is used to determine the preferred orbit planes into which gas will settle in the external potential of a triaxial galaxy tumbling about a principal axis of its mass distribution. It is found that more than one preferred plane can exist at a given radial distance from a galaxy's center. The number and orientations of the planes depend on radius, tumble rate, and the orientation of the tumble axis. Comparison with previous investigations of periodic orbits by other authors allows their results to be generalized. Observational consequences of the preferred plane calculations and possible applications to dust lane ellipticals and galaxies with warped or orthogonal gas disks are discussed. Precession trajectories for gas orbits not in preferred planes are determined, and the implications for inflow and possible catastrophic infall are examined.
