Abstract: We have searched for inclusive [eta] production in [tau] decays using a data sample of 2553 events of e+e- -->[tau]+[tau]- in the one-three topology. The data were obtained using the High Resolution Spectrometer at [radical sign]s=29 GeV. A 90% confidence level upper limit on the process [tau]+/- -->[pi]+/-[eta]X of 2.1% is found. Using [tau] decays to five charged particles limits of 0.5% on [tau]+/- -->[pi]+/-[eta][eta]X and 0.3% on [tau]+/- -->[pi]+/-[pi]+[pi]-[eta]X are also obtained.
