Abstract
We present a new technique for the calculation of helicity gravitino production during preheating. It is based on the equivalence between goldstinos and helicity gravitinos at high energies. The problem is thus reduced to the standard (Majorana) fermion production after inflation. Comparison with the results obtained in the unitary gauge is also presented.
