Following the deadly June crash of an Air India Boeing 787 in Ahmedabad, India’s aviation regulator has directed all airlines to inspect the fuel switch locking systems on Boeing 737 and 787 aircraft. While Boeing and the FAA assure the system is safe, India and other countries are conducting precautionary checks. Air India has already inspected most of its affected fleet, with no issues found so far. Investigators noted previous FAA guidance on the switches and discrepancies in cockpit communication before the crash.
