## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 777-200 and -300 series airplanes. This proposed AD would require applying an anti-static conductive coating to the fuel access and thermal anti-icing blowout doors at the location of the bonding fasteners on the leading edge of the wings, and performing a resistance test on the new coating to ensure correct ground path resistance. This proposed AD is prompted by a report that an anti-static coating was not applied correctly on doors located within a flammable fluid leakage zone. We are proposing this AD to prevent an uncontrollable fire in the leading edge of the wing, which could damage critical wing structures and cause a fuel tank explosion.
