  We study here the generalized Weimar-Woods contractions of the superalgebra
$osp(1|32) \oplus osp(1|32)$ in order to obtain a suitable algebra that could
describe the gauge group of $D=11$ supergravity. The contracted superalgebras
are assumed to be given in terms of fermionic extensions of the M-theory
superalgebra. We show that the only superalgebra of this type obtained by
contraction is the only one for which the three-form of $D=11$ supergravity
cannot be trivialized. Therefore, $D=11$ supergravity cannot be connected in
this way with a contraction of $osp(1|32) \oplus osp(1|32)$.
