Airworthiness Directives; Airbus SAS Airplanes
Summary
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A330-200 series and A330-300 series airplanes. This AD was prompted by reports of cracked flexible hoses in the courier area oxygen system (CAOS). This AD requires repetitive detailed inspections of the CAOS and replacement of affected parts if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
