India’s civil aviation authority has ordered an inspection of cockpit fuel switches on Boeing Co. 737 and 787 aircraft operating in the country following a preliminary report into the deadly crash of an Air India 787 last month that was caused by a cut-off in kerosene supply.

The FAA had first flagged concerns in December 2018 through a special Airworthiness Information Bulletin (SAIB) that warned of possible disengagement of the fuel control switch locking mechanism on a broad range of Boeing aircraft, spanning from the 717 and various 737 variants to the larger 747, 757, 767, and all models of the 787 Dreamliner.
