Federal Aviation Administration January 31, 2022 – Federal Register Recent Federal Regulation Documents

The FAA proposes to supersede Airworthiness Directive (AD) 2021-02-20, which applies to certain H[eacute]licopt[egrave]res Guimbal Model Cabri G2 helicopters. AD 2021-02-20 requires initial and repetitive inspections of certain rotating and non-rotating scissor fittings, and depending on the results, replacing the affected assembly. AD 2021-02-20 also prohibits installing certain main rotor hubs (MRHs) and swashplate guides unless the initial inspection has been accomplished. Since the FAA issued AD 2021-02-20, the MRH and swashplate guide have been redesigned to include a certain part- numbered scissor fitting. This proposed AD would retain certain requirements of AD 2021-02-20, require installation of newly designed parts, provide a terminating action for the initial and repetitive inspections, and revise the applicability. This proposed AD would also extend the repetitive inspection interval and prohibit installing certain MRHs and swashplate guides. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain Umlaut Engineering GmbH (previously P3 Engineering GmbH) HAFEX (Halon-free) hand-held P3HAFEX fire extinguishers (fire extinguishers). This AD was prompted by reports of a quality control issue on certain fire extinguishers, where the spindle geometries of the fire extinguishers were found to be out of tolerance. This AD requires removing affected fire extinguishers from service. 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 The Boeing Company Model 737-8, 737-9, and 737-8200 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 takeoffs and landings, as a result of this interference, certain airplane systems may not properly function, resulting in longer than normal landing or rejected takeoff distances due to the effect on thrust reverser deployment, spoilers, speedbrake deployment, and increased idle thrust, regardless of the approach type or weather. This AD requires revising the limitations and operating procedures sections of the existing airplane flight manual (AFM) to incorporate limitations prohibiting the use of certain minimum equipment list (MEL) items, and to incorporate operating procedures for calculating takeoff and landing distances, 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.

This action establishes Class E airspace extending upward from 700 feet above the surface of the earth at Joseph State Airport, Joseph, OR. The establishment of airspace supports the airport's transition from visual flight rules to instrument flight rule (IFR) operations and ensures the safety and management of IFR operations within the National Airspace System.
