Stop misinformation, the government did not hand over the manufacturing of Tejas fighters to private sector. HAL is still responsible for the final assembly of Tejas. What has changed is that for once, HAL has been forced to offload fabrication of fuselage, wing segments, and wiring harness, subsystems to private contractors, rather than doing it themselves and then quote an ungodly amount of man-hours for pricing the aircraft. Which is the correct and proper way. For the first time in their lives HAL has been forced to start learning modern supply chain management and undertake vendor management. A job ISRO has been doing far successfully than HAL.
