  We performed a search for any sign of an additional neutrino mass state in
beta-electron spectrum based on data reanalysis of direct electron antineutrino
mass measurements in Tritium beta-decay in the Troitsk nu-mass experiment. The
existing data set allows us to search for such a state in the mass range up to
100 eV. The lowest value at a 95% C.L. upper limit for the contribution of a
heavy eigenstate into electron neutrino is around or less than 1% for masses
above 20 eV.
