My understanding is that Boeing will not do final assembly in China, presumably to protect their manufacturing process secrets. Airbus is different, I think. Sorry this is not directly responsive to your question. I will be interested in other replies from experts.
Sectorial data for FDI is available for specific industries like pharma, automobiles, etc in India. This would include the aviation industry as well. However, company specific details can be found only through Annual Reports of the specific company. Sorry, this doesn't answer your question entirely, but it may help going through the annual report !!
