We report an analysis of τ- decaying into ωπ-ντ with ω→π+π-π0 using a data sample containing nearly 320×106τ pairs collected with the BABAR detector at the PEP-II B-Factory. We find no evidence for second-class currents, and we set an upper limit of 0.69% at 90% confidence level for the fraction of second-class currents in this decay mode.
