FAA reveals flaw in another major Boeing plane that could result in fuel tank exploding

- Boeing planes, particularly the 777 liners, have a potential flaw near the fuel tank that could result in explosions - Nearly 300 Boeing 777 airplanes across the US are at risk - Proposed repairs by FAA include installing electrical bonding and grounding, costing roughly $14 million - Boeing operators and airlines are responsible for making the repairs - The vulnerability is not an immediate safety concern, per Boeing - Boeing has been under scrutiny for various issues on its planes, including quality control problems with supplier Spirit AeroSystems, and a previous incident with a door plug blowing out - FAA proposed a similar direction in 2017 to address safety concerns in the 777 models
