which will be commenced as soon as stall characteristics were refined. All efforts were being made to achieve FOC by December 2014. Production of aircraft was to commence immediately thereafter. However the stall cannot be tested until HAL redesigns the entire aircraft to correct its "inherent asymmetry". BAE Systems was consulted on certain design changes, specifically the tail. Afterwards the design was put to mathematical and wind tunnel tests. The modified aircraft was expected to complete the spin tests by September 2015, and the production of 85 aircraft for the Indian Air Force to begin. 2017 In March 2017, Jane's reported that due to the HJT-36's "unsolvable" issues associated with critical stall and spin characteristics the aircraft is not ready to serve as an intermediate jet trainer for Indian Air Force pilots. 2019 With Birhle as a consultant, the air frame was modified to move the tailfin and tailplane further down which is expected to make spin recovery easier. The modified aircraft flew for the first time in April 2019. 2022 On 6th January, the IJT has successfully demonstrated the capability to carry out six turn spins to both the left and right hand sides.
