Using 5.63 pb-1 of data accumulated at the psi(2S) resonance with the CLEO III and CLEO-c detectors corresponding to 3.08×106 psi(2S) decays, a search is performed for the decay psi(2S)-->etacpi+pi-pi0 to test a theoretical prediction based upon the assumption that the c[overline c] pair in the psi(2S) does not annihilate directly into three gluons but rather survives before annihilating. No signal is observed, and a combined upper limit from six etac decay modes is determined to be [script B](psi(2S)-->etacpi+pi-pi0)<=1.0×10-3 at 90% C.L. This upper limit is about an order of magnitude below the theoretical expectation.
