  We report the first measurement of target single spin asymmetries in the
semi-inclusive $^3{He}(e,e'\pi^\pm)X$ reaction on a transversely polarized
target. The experiment, conducted at Jefferson Lab using a 5.9 GeV electron
beam, covers a range of 0.14 $< x <$ 0.34 with 1.3 $<Q^2<$ 2.7 GeV$^2$. The
Collins and Sivers moments were extracted from the azimuthal angular dependence
of the measured asymmetries. The extracted $\pi^\pm$ Collins moments for $^3$He
are consistent with zero, except for the $\pi^+$ moment at $x=0.34$, which
deviates from zero by 2.3$\sigma$. While the $\pi^-$ Sivers moments are
consistent with zero, the $\pi^+$ Sivers moments favor negative values. The
neutron results were extracted using the nucleon effective polarization and the
measured cross section ratio of proton to $^3$He, and are largely consistent
with the predictions of phenomenological fits and quark model calculations.
