Airworthiness Directives; Airbus Model A318, A319, A320, and A321 Series Airplanes Equipped With Air Cruisers/Aerazur Forward and Aft Passenger Door Emergency Escape Slides

摘要

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A318, A319, A320, and A321 series airplanes equipped with certain forward and aft passenger door emergency escape slides. This proposed AD would require modifying the forward and aft door slides. This proposed AD is prompted by manufacturer testing that has shown contact between the inflation hose and fabric roll, within a short period of time after inflation of the emergency escape slides, can rupture the inflation hose at its end fittings. We are proposing this AD to prevent interference between the inflation hose and slide fabric and rupture of the inflation hose, which could result in incomplete inflation of the emergency escape slides and consequent unavailability of those slides during an emergency evacuation.
