Airworthiness Directives; Airbus Model A320 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A320 series airplanes. This proposed AD would require replacing the carbon fiber reinforced plastic (CFRP) actuator fittings of the rudder with aluminum actuator fittings and doing related investigative and corrective actions. This proposed AD results from rupture of a CFRP actuator fitting during maintenance. We are proposing this AD to prevent rupture of a rudder actuator fitting, which could result in reduced controllability of the airplane.
Airworthiness Directives; Bombardier Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A and CL-601-3R) Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Bombardier Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL- 600-2B16 (CL-601-3A and CL-601-3R) airplanes. This AD requires implementing a corrosion prevention and control program (CPCP) either by accomplishing specific tasks or by revising the maintenance inspection program to include a CPCP. This AD results from the determination that, as airplanes age, they are more likely to exhibit indications of corrosion. We are issuing this AD to prevent structural failure of the airplane due to corrosion.
Airworthiness Directives; Bombardier Model DHC-8-400 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model DHC-8-400 series airplanes. This AD requires repetitive cleaning/inspecting of the drain hole of each pitot static probe and repetitive cleaning of the pitot lines in the pitot static system. This AD results from reports of incidents of airspeed mismatch between the pilot, co-pilot, and standby airspeed indications caused by contamination in the pitot static system. We are issuing this AD to prevent erroneous/misleading altitude and airspeed information from a contaminated pitot static system to the flightcrew, which could reduce the ability of the flightcrew to maintain the safe flight and landing of the airplane.
Human Space Flight Requirements for Crew and Space Flight Participants
The FAA is establishing requirements for human space flight as required by the Commercial Space Launch Amendments Act of 2004, including rules on crew qualifications and training, and informed consent for crew and space flight participants. The requirements should provide an acceptable level of safety to the general public and ensure individuals on board are aware of the risks associated with a launch or reentry. The rule also applies existing financial responsibility and waiver of liability requirements to human space flight and experimental permits. Experimental permits are the subject of a separate rulemaking.
Airworthiness Directives; Sicma Aero Seat; Third Occupant Seat Assemblies, 133 Series
The FAA is adopting a new airworthiness directive (AD) for Sicma Aero Seat third occupant seat assemblies, 133 series. This AD requires visually inspecting the installation of the two headrest bushings and installing Mecanindus pins to secure the bushings. This AD results from Sicma's determination that missing or incorrectly secured bushings could loosen and cause disengagement of the headrest from the seat during a high-energy stop of the airplane, possibly injuring the seat occupant. We are issuing this AD to prevent disengagement of the headrest from the seat during a high-energy stop of the airplane that could injure the seat occupant.
