Let $G$ be a finite group. A subset $X subseteq G$ is called a pairwise non-commuting set if $xy neq yx$ for all distinct elements $x, y in X$. If $|X| geq |Y|$ for every other pairwise non-commuting set $Y$ in $G$, then $X$ is called a maximal pairwise non-commuting set. A $p$-group $G$ is defined as an $A_2$-group if it contains a nonabelian subgroup of index $p$ such that all subgroups of index $p^2$ are abelian. In this paper, we determine the exact maximum size of such sets in finite $A_2$-groups.
