Unsafe Condition
Failure of the fuel pump Non Return Valve (NRV) preventing the collector cell jet pump from working, leading to engine collector cell fuel level dropping below the pump inlet and causing engine flame out. Multiple NRV failures combined with failure modes trapping fuel could increase unusable fuel, potentially leading to fuel starvation and engine in-flight shutdown.
