Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A300 B2 and B4; A310; and A300 B4-600, B4-600R, and F4-600R (collectively called A300-600) series airplanes. This proposal would require modification of certain components related to the fuel level sensors. This action is necessary to prevent the possibility of overheating of the fuel level sensors, which could lead to the risk of explosion in the fuel tank. This action is intended to address the identified unsafe condition.
