  We show that in D=4 AdS, $s\ge 3/2$ partially massless (PM) fermions retain
the duality invariances of their flat space massless counterparts. They have
tuned ratios $ {m^2}/{M^2}\ne 0$ that turn them into sums of effectively
massless unconstrained helicity $\pm(s,\cdots,\frac{3}{2})$ excitations, shorn
of the lowest (non-dual)\helicity $\pm \frac{1}{2}$-rung and -more generally-
of succeeding higher rung as well. Each helicity mode is separately duality
invariant, like its flat space counterpart.
