  The new contributions to the charmless B decay $B \to X_{s}\eta^{\prime}$
from the unit-charged technipions $P^{\pm}$ and $P^{\pm}_{8}$ are estimated.
The technipions can provide a large enhancement to the inclusive branching
ratio: $Br(B \to X_{s}\eta^{\prime}) \sim 7\times 10^{-4}$ for $m_{p1}=100GeV$
and $m_{p8}=250 \sim 350 GeV$ when the effect of QCD gluon anomaly is also
taken into account. The new physics effect is essential to interpret the CLEO
data.
