India's Aircraft Accident Investigation Bureau (AAIB) found that fuel switches had flipped to cutoff position—a move typically done only after landing—just 50 seconds into the flight as the aircraft climbed to 625 feet. The cockpit voice recorder captured one pilot asking the other why he cut off the fuel, with his colleague replying that he hadn't. The switches flipped a second apart, roughly the time it would take to shift one and then the other manually. //

Both fuel switches were found in the run position with indications that both engines were attempting to relight before the crash.
