Is there something odd about the fuel system
Not the airframe fuel system, the engine design is the common factor, as the article says
A 787 powered by GE Aviation GEnx-1B turbofans suffered such an issue in March after that aircraft’s fuel tanks had been treated with Kathon FP 1.5. Both the 787’s engines lost thrust during descent into Kansai, Japan.
The 737 Max’s Leap-1Bs, having “similar fuel system architecture” as the GEnx, “are also considered susceptible to a multi-engine loss-of-thrust-control event”, the FAA says.
