Aviation regulator DGCA on Monday asked airlines to inspect the fuel switch locking system in their Boeing 787 and 737 planes, reported the PTI.

The DGCA's decision comes days after the preliminary probe report into the Air India's Boeing 787 crash found that the switches were cut off before the accident last month.

The Federal Aviation Administration (FAA), back in 2018, had flagged the potential disengagement of the fuel control switch locking feature on certain models of Boeing aircraft, including 787s and 737s. It was mentioned in a Special Airworthiness Information Bulletin (SAIB) but there was no airworthiness directive, indicating that the issue was not a safety concern, according to the PTI.
