## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A319, A320, and A321 series airplanes. This proposed AD would require replacing certain flight warning computers (FWCs) with improved FWCs. This proposed AD is prompted by mandatory continuing airworthiness information issued by a foreign civil airworthiness authority. The actions specified in this proposed AD are intended to ensure that radioaltimeter malfunctions are annunciated to the flightcrew, and to prevent consequent erroneous autopilot behavior during approach and landing. This action is intended to address the identified unsafe condition.
