Summary

We propose to adopt a new airworthiness directive (AD) for all Airbus Model A318 and A319 series airplanes; Model A320-211, A320-212, A320-214, A320-216, A320-231, A320-232, and A320-233 airplanes; and Model A321-111, A321-112, A321-131, A321-211, A321-212, A321-213, A321- 231, and A321-232 airplanes. This proposed AD was prompted by reports of missing assembly hardware on the trimmable horizontal stabilizer actuator (THSA). This proposed AD would require repetitive inspections and checks of the lower and upper THSA attachments and applicable related investigative and corrective actions; a one-time inspection of the THSA lower attachment and replacement as applicable; and, for certain airplanes, activation of the electrical load sensing device (ELSD) and concurrent modifications. We are proposing this AD to address the unsafe condition on these products.
