Abstract. The central star of the planetary nebula Abell 43 (WD 1751+106) is one of only four known so-called hybrid PG1159 stars. These are hydrogen-deficient due to a late thermal pulse.We present results of a spectral analysis of FUSE, HST /GHRS, and IUE UV observations by means of NLTE model-atmosphere techniques.
