We present the results of QCD analysis of out-of-event-plane momentum
distribution in 3-jet e+e- annihilation events. We consider the all-order
resummed perturbative prediction and the leading power suppressed
non-perturbative corrections to the mean value <K_out> and the distribution and
explain their non-trivial colour structure. The technique we develop aims at
improving the accuracy of the theoretical description of multi-jet ensembles,
in particular in hadron-hadron collisions.
