Boeing and the United States Federal Aviation Agency (USFAA) recently notified that the fuel switch locks used in flight are safe, as per a report from Reuters. This comes at a time when the fuel switch lock mechanics have come under scrutiny amid the ongoing investigation into the Air India AI 171 crash.

Pilots typically operate the fuel control switches during two key phases: At engine start-up on the ground and during engine shutdown after landing.

South Korea is preparing to order all airlines in the country that operate Boeing jets to examine the fuel switches at the centre of an investigation into a deadly Air India crash that killed 260 people.
