India's aviation watchdog warned Air India Express earlier this year for failing to replace engine parts on time as required by the European Union Aviation Safety (EASA), according to an official memo.

The PNF confirms a positive rate of climb on his VSI and raises the undercarriage lever (also a lock and toggle switch). These calls have been omitted in the preliminary report. Why was the landing gear in the down position all the way till the crash?

The Air India crash involving the Boeing 787-8 Dreamliner on June 12 is one of the deadliest tragedies in Indian aviation history.
