Yes, this was expected. Because both Indian private sector and government sector is new in this. None of them have experience to undertake such kind of huge and critical project which last long 15-20 years in aviation.
The contracts and the business arrangements will be written multiple times to suit the both parties and only then signed. Government may be studying the Rafale deal project and implementing similar if not same in this. Because this is a research project too. Building it from scratch, testing it and then putting it on production line, none have experience to carry out this kind of project at management level.
Its very complicated, we are new in this. Can't be compared to LCA because LCA was completely built by government and it's PSUs.
