## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A310 series airplanes and Airbus Model A300 B4-600, B4-600R, and F4-600R (collectively called A300-600) series airplanes. This proposal would require revising the Airplane Flight Manual to prohibit the airplane from being moved during inertial reference unit alignment. This action is necessary to prevent a loss of positioning data and a display of incorrect attitude data to the flight crew, which could result in severe consequences to the airworthiness of the airplane if operated under flight conditions with no visual reference. This action is intended to address the identified unsafe condition.
