## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A300 B2; A300 B4; A300 B4-600, B4-600R, and F4-600R (collectively called A300-600); A310; A319; A320; A321; A330; and A340 series airplanes. This proposal would require replacement of Labinal actuators in certain powered cockpit seats by new improved actuators. This action is necessary to prevent uncommanded horizontal movement of the cockpit seats or loss of ability to lock the seats in place during flight, which could limit the ability of the crew to perform necessary tasks, leading to reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
