Airworthiness Directives; Airbus SAS Airplanes

FAA / Federal Register · 2021-16561

The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-200, -200 Freighter, -300, -800, and -900 series airplanes; and Model A340-200 and -300 series airplanes. This AD was prompted by reports of incorrect installation of the lower attachment parts of the trimmable horizontal stabilizer actuator (THSA). This AD requires doing a detailed inspection of the THSA lower attachment parts for discrepancies and corrective action if necessary, and prohibits using earlier versions of certain airplane maintenance manual (AMM) tasks, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
