Petrov classification of supergravity

N=1 supergravity is analyzed in light of the Petrov classification scheme. It is found that the (2, 3/2) chiral multiplet obtained must be recognized as the Weyl submultiplet, Wsub(abα), where only (3/2, 0)+(0, 3/2) components contribute. Due to the SUSY transformation laws the classes of solutions allowed for various Petrov types are shown to be restrictive - indeed, in certain instances there can be no consistent solution. The freedom left in the solutions and their possible interpretation are discussed. One-loop invariants are also considered by resorting to non-covariant forms. (orig.)
