Last 58T's I saw in this part of the world were Indonesian Registered operated by Airfast I believe
A lot of the Indo 58Ts were written off in accidents I've searched around trying to buy engines and major components for US buyers but anything remaining was sold off or scrapped long ago

7 out of 16 helis on the register written off is a pretty high accident rate (44%)
I do occassionally run across some smaller S58T components (when we buy surplus mixed spares packages) with Air Asia Taiwan (Air America) tags on it !
