FAA Airworthiness Directive Regarding Boeing 787-8
All Boeing 787 Dreamliners currently in service are being required to confirm that fuel line connectors have been properly installed. Fuel leaks in Dreamliners were traced to a manufacturing flaw at Boeing plants.
The FAA said “A safety order mandated inspection of fuel line couplings in the engine pylons to verify the couplings are correctly assembled and installed”
