Federal Aviation Administration January 11, 2022 – Federal Register Recent Federal Regulation Documents

The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. 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 General Electric Company (GE) GE90 model turbofan engines. This AD was prompted by two separate in-flight shutdowns (IFSDs) resulting from failure of the transfer gearbox (TGB) radial bevel gear (TGB radial gearshaft). This AD requires visual inspection of the TGB radial gearshaft and, depending on the results of the inspection, replacement of the TGB radial gearshaft. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2019-03- 26, which applied to certain The Boeing Company Model 737-600, -700, - 700C, -800, -900, and -900ER series airplanes. AD 2019-03-26 required modifying the passenger service units (PSUs) and life vest panels by replacing the existing inboard lanyard and installing two new lanyards on the outboard edge of the PSUs and life vest panels; measuring the distance between the hooks of the torsion spring of the lanyard assembly; replacing discrepant lanyard assemblies; and re-identifying serviceable lanyard assemblies. This AD was prompted by a determination that certain airplanes are listed in the wrong configuration and certain PSUs have not been correctly re-identified. This AD retains the requirements of AD 2019-03-26, and, for certain airplanes, requires an inspection to determine if the re-identified PSU part number is correct, and further re-identification if necessary. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2020-07- 17, which applied to all Saab AB, Support and Services Model SAAB 2000 airplanes. AD 2020-07-17 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2020-07- 17, it has determined that new or more restrictive airworthiness limitations are necessary. This AD retains the requirements of AD 2020- 07-17 and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in a European Union Aviation Safety Agency (EASA) AD. The FAA is issuing this AD to address the unsafe condition on these products.

The Federal Aviation Administration (FAA) is considering a proposal from the City of Kansas City, MO, to release a 13.94 acre parcel of land from the federal obligation dedicating it to aeronautical use and to authorize this parcel to be used for revenue- producing, non-aeronautical purposes.
