Except when they are not:

From the avherald link:

>Service Bulletins by Boeing issued in year 2018 recommending to upgrade the fuel switches to locked versions to prevent inadvertent flip of the switches, as well as the FAA/GE issued Service Bulletin FAA-2021-0273-0013 Attachment 2 relating to loss of control issue (also see above) were NOT implemented by Air India.

You've linked to something regarding an ECU component. Nothing about fuel switches. "This Service Bulletin provides instructions to replace the EEC MN4 bridge ball grid array (BGA) microprocessor"
