Federal Aviation Administration February 6, 2020 – Federal Register Recent Federal Regulation Documents

The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 airplanes. This AD was prompted by a determination that ram air turbine (RAT) performance may be below the expected (certificated) level when the landing gear is extended. This AD requires installing flight control and guidance system (FCGS) software (SW) X11 Standard (STD), 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.

The FAA is superseding Airworthiness Directive (AD) 2017-15- 04, which applied to certain The Boeing Company Model 787-8 and 787-9 airplanes. AD 2017-15-04 required replacement of affected electromechanical actuators (EMAs). This AD retains the requirements of AD 2017-15-04; expands the applicability to include all The Boeing Company Model 787 series airplanes; and adds a new requirement to identify, for certain airplanes, the part number of EMAs and to replace affected EMAs. This AD was prompted by wire harness chafing on the EMAs for certain spoilers due to insufficient separation with adjacent structure. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-200 Freighter series airplanes, Model A330-200 series airplanes, Model A330-300 series airplanes, Model A340-200 series airplanes, Model A340-300 series airplanes, Model A340-541 airplanes, and Model A340-642 airplanes. This AD was prompted by the absence of a requirement to remove certain Emergency Procedures in the existing Aircraft Flight Manual (AFM) after accomplishing a certain modification. This AD requires, for airplanes on which a certain modification is done, revising the AFM by removing certain Emergency Procedures in the AFM, 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.

The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by a report indicating that during inspection of the installation of oxygen containers, certain fasteners of the oxygen containers and adjacent panels in the passenger supply channels (PSCs) were found damaged or unlocked, which could result in insufficient clearance between the oxygen container and adjacent panels. This AD requires a one-time inspection of the oxygen containers and adjacent panels and applicable corrective actions, 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.
