## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A300 B4-600 Series Airplanes, Model A300 B4-600R Series Airplanes, Model A300 C4-605R Variant F Airplanes, and Model A300 F4-605R Airplanes. This proposal would require modification of certain components of the 115 Volts Alternating Current (VAC) supply wiring and of the fuel gauging system. This action is necessary to prevent short circuits between 115 VAC wiring and certain fuel system electrical wire runs with subsequent overheating of the cadensicon sensor thermistor or fuel level sensor, which could be great enough to ignite fuel vapors in the fuel tank and cause an explosion. This action is intended to address the identified unsafe condition.
