Unsafe Condition
No controlled bonding provisions are present on critical locations inside the fuel tank or connected to the fuel tank wall, and no anti-spray cover is installed on the fuel shut-off valve (FSOV) in both wings. This could create an ignition source in the fuel tank vapor space, possibly resulting in a fuel tank explosion and consequent loss of the airplane.

Required Actions
Install additional bonding provisions at applicable locations inside the fuel tank and install an anti-spray cover on the FSOV in both wings.
