Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A320-214, -232, and -233 airplanes; and Airbus Model A321-211 and -231 airplanes. This proposed AD was prompted by reports of incorrect installation of jiffy joint connectors on cables connected to certain passenger service units (PSU), which could cause the passenger oxygen container to malfunction if the connector becomes disengaged during flight due to vibration. This proposed AD would require identification of the affected PSUs, and depending on findings, doing applicable related investigative and corrective actions. We are proposing this AD to prevent failure of the door of the passenger oxygen container to open in the event of airplane decompression, resulting in lack of oxygen supply and consequent injury to occupants.
