  We reanalyse the limits on the gravitino mass $m_{3/2}$ in superlight
gravitino scenarios derived from arguments on energy-loss during gravitational
collapse. We conclude that the mass range $10^{-6}eV\leq
m_{3/2}\leq2.3\times10^{-5}eV$ is excluded by SN1987A data. In terms of the
scale of supersymmetry breaking $\Lambda$, the range $70GeV\leq\Lambda \leq
300GeV$ is not allowed.
