Unsafe Condition

Corrosion of the out-tank wire harness of the spar connector backshell for the fuel quantity indication system (FQIS), which could prevent correct grounding of the lightning shield and result in total loss of the electrical grounding between the lightning shield and the airplane structure. This condition, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
