We report on a search for direct CP violation in the singly Cabibbo-suppressed decay D[superscript +]-->K[superscript +]K[superscript -]π[superscript +] using a data sample of 476 fb[subscript -1] of e[superscript +]e[superscript -] annihilation data accumulated with the BABAR detector at the SLAC PEP-II electron-positron collider, running at and just below the energy of the Υ(4S) resonance. The integrated CP-violating decay rate asymmetry A[subscript CP] is determined to be (0.37±0.30±0.15)%. Model-independent and model-dependent Dalitz plot analysis techniques are used to search for CP-violating asymmetries in the various intermediate states. We find no evidence for CP-violation asymmetry.
