Airworthiness Directives; Airbus SAS Airplanes

FAA / Federal Register · 2021-12175

The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A330-200, A330-300, A340-200, A340-300, A340- 500, and A340-600 series airplanes. This AD was prompted by reports that, for certain lower deck mobile crew rest (LDMCR) units, the connection of a certain halon outlet tube to the outlet of a certain fire extinguisher bottle may be incorrect. This AD requires replacing each affected halon outlet tube with a flexible hose, 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.
