## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Boeing Model 777 series airplanes. This proposal would require replacing four socket contacts on the four boost pumps of the main fuel tanks with new, high-quality gold-plated contacts, and sealing the backshell of the connector with potting compound. This action is necessary to prevent a possible source of ignition in a flammable leakage zone, which could result in an undetected and uncontrollable fire in the wheel well or wing trailing edge, and a possible fuel tank explosion. This action is intended to address the identified unsafe condition.
