## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 767-200, -300, and -300F series airplanes. This proposed AD would require a one-time inspection of each fuel quantity indication system (FQIS) wire harness connector for corrosion of the shield-to-backshell connection, corrosion on the ground jumper, and damage to the ground jumper; a loop resistance test of each FQIS wire harness; and related investigative and corrective actions if necessary. This proposed AD results from reports of corrosion of the out-tank wire harness of the spar connector backshell for the FQIS. We are proposing this AD to detect and correct corrosion of the out-tank wire harness, 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 theairplane.
