Federal Aviation Administration August 24, 2023 – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2B16 (604 Variant) airplanes. This proposed AD was prompted by a report that some airplanes were delivered without a portable protective breathing equipment (PBE) device located in the forward left side cabin area of the airplane. This proposed AD would require visually inspecting the forward left side cabin area of the airplane to determine if the portable PBE device is installed and, if not installed, would require installing the portable PBE device along with the associated placard. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Thales AVS France SAS (Thales) flight management computer navigation modules (FMC2 NAVM) installed on, but not limited to, airplanes. This AD was prompted by reports that, due to software issues, certain FMC2 NAVM navigation modules provide erroneous data to the flight management computer, compromising safe flight of the airplane. This proposed AD would require revising the existing aircraft flight manual (AFM) for your airplane and updating the navigation database. This proposed AD would also prohibit installing a database unless certain procedures were removed. The FAA is proposing this AD to address the unsafe condition on these products.
