Well Dassault as OEM has the intellectual Property Rights over those parts along with drawings and manufacturing process. There is no reason to believe why that can't be done in India if Dassault wishes to. It won't happen overnight, but (as was the case with Su 30 MKI), slowly one can increase indigenous content, Indian Industry can well do that.
& in this context that i believe, that India will ask France to Guarantee this ToT to India and use the initial number as Dangling Carrot infront policy.
Now that Dassault gets the choice of selecting its partner in India, one of the biggest issues of OEM standing guarantee for all planes to be assembled in India will be sorted out and maybe we can get speedier deliveries.
The reason i say all this is since Dassault is already executing orders for France and Egpyt deal coming up, it will not be possible to cover a possible Indian order with facilities in France alone. It will have to bring in assembly lines to India to meet the contractual timeline obligations.
