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 proposal would require performing a general visual inspection of the outer handle flap mechanisms of the passenger doors for the presence of corrosion inhibitor and for correct operation; cleaning, if necessary; and greasing. This action is necessary to prevent blockage of the outer handle flap in an intermediate pushed-in position, which may prevent a passenger door from opening from the inside of the airplane, thereby delaying an emergency evacuation. This action is intended to address the identified unsafe condition.
