  Superscaling approximation (SuSA) predictions to neutrino-induced
charged-current charged pion production in the \Delta-resonance region are
explored under MiniBooNE experimental conditions. The results obtained within
SuSA for the flux-averaged double-differential cross sections of the \pi+
production for the \nu_\mu+CH_2 reaction as a function of the muon kinetic
energy and of the scattering angle, the cross sections averaged over the angle,
the total cross section for the \pi+ production, as well as CC1\pi+ to CCQE
cross section ratio are compared with the corresponding MiniBooNE experimental
data. The SuSA predictions are in good agreement with data on neutrino flux
average cross-sections, but a somewhat different dependence on the neutrino
energy is predicted than the one resulting from the experimental analysis.
