Federal Aviation Administration February 14, 2022 – Federal Register Recent Federal Regulation Documents

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 that during type certification activity, it was identified that certain monitoring software was incorrectly implemented in the braking control system (BCS) certification standard. This AD requires installing (updating) certain software for the braking and steering system, 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.

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval to renew an information collection. The collection involves the submission of an application to obtain a Letter of Deviation Authority to permit flight instruction for compensation or hire aboard experimental category aircraft under 14 CFR 91.319. The information to be collected will be used to determine whether such flight instruction can be conducted safely.

The FAA is adopting a new airworthiness directive (AD) for all General Electric Company (GE) Passport 20-17BB1A, Passport 20-18BB1A, and Passport 20-19BB1A model turbofan engines. This AD was prompted by a report of a manufacturing quality escape that requires a reduction to the life limit of certain high-pressure turbine (HPT) rotor stage 1 disks. This AD requires revising the airworthiness limitations section (ALS) of the existing maintenance manual and the operator's existing approved continuous airworthiness maintenance program (CAMP) to incorporate a reduced life limit for certain HPT rotor stage 1 disks. 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, -300, -800, and -900 series airplanes; and Model A340-200, -300, -500, and -600 series airplanes. This AD was prompted by reports that the instructions on the doghouse door lock placard are unclear and incomplete. This AD requires replacing the placard with an improved instruction placard, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also prohibits the installation of affected parts under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.

These special conditions are issued for the Dassault Aviation (Dassault) Model Falcon 6X airplane. This airplane will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. This design feature is an electronic flight-control system (EFCS) associated with lateral-directional and longitudinal stability, and low-energy awareness. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 757 airplanes and Model 767 airplanes. This AD was prompted by a determination that radio altimeters cannot be relied upon to perform their intended function if they experience interference from wireless broadband operations in the 3.7-3.98 GHz frequency band (5G C-Band), and a recent determination that, during approach, landings, and go-arounds, as a result of this interference, certain airplane systems may not properly function, resulting in increased flightcrew workload while on approach with the flight director, autothrottle, or autopilot engaged. The FAA is issuing this AD to address 5G C-Band interference that could result in increased flightcrew workload and could lead to reduced ability of the flightcrew to maintain safe flight and landing of the airplane. This AD requires revising the limitations and operating procedures sections of the existing airplane flight manual (AFM) to incorporate specific operating procedures for landing distance calculations, instrument landing system (ILS) approaches, non-precision approaches, speedbrake deployment, and go-around and missed approaches, when in the presence of 5G C-Band interference as identified by Notices to Air Missions (NOTAMs). The FAA is issuing this AD to address the unsafe condition on these products.
