S-92 cabins have never been built domestically. MHI was doing production for quite a while. Aside form that, Embraer was building the sponsons, AIDC was doing the cockpit, JIDC did the tail rotor pylon, and Gamesa did the transition.
I do find it humorous that the entire push for Sikorsky to partner with Tata in India was to try and get a bit of local leverage with the S-92 for the VVIP contract - which famously was awarded to AW with the 101 and subsequently turned into "Choppergate"
