Federal Aviation Administration November 6, 2023 – Federal Register Recent Federal Regulation Documents

The FAA is superseding Airworthiness Directive (AD) 2013-26-10 for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211- 524G2-19, RB211-524G3-19, RB211-524H-36, and RB211-524H2-19 engines. AD 2013-26-10 required a one-time reduction in the cyclic life of certain high-pressure compressor (HPC) rotor stage 1 and stage 2 disks, and removal of disks that exceed the reduced cycle life. Since the FAA issued AD 2013-26-10, the manufacturer has revised the engine time limits manual (TLM), introducing new and more restrictive instructions. This AD is prompted by the manufacturer revising the engine time limits manual, introducing new and more restrictive instructions. This AD requires revisions to the airworthiness limitations section (ALS) of the operator's existing approved engine maintenance or inspection program, as applicable, 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.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD- 500-1A11 airplanes. This proposed AD was prompted by a report of possible chafing of a power harness at fuselage frame (FR) 65. This proposed AD would require rerouting the power harness, as specified in a Transport Canada AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2022-18- 14, which applied to certain Airbus SAS Model A330-200 series, A330-200 Freighter series, A330-300 series, A330-800 series, and A330-900 series airplanes. AD 2022-18-14 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD continues to require the actions in AD 2022-18- 14, and also requires revising the existing maintenance or inspection program, as applicable to incorporate additional new or more restrictive airworthiness limitations; as specified in two European Union Aviation Safety Agency (EASA) ADs, which are incorporated by reference. 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 Embraer S.A. (Embraer) Model EMB-505 airplanes. This AD was prompted by occurrences of an uncommanded change in the setting of the barometric pressure in both primary flight displays (PFDs). This AD requires installing a new version of the airplane avionics system software, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2018-03-13 for certain General Electric Company (GE) Model CT7-5A2, CT7-5A3, CT7- 7A, CT7-7A1, CT7-9B, CT7-9B1, CT7-9B2, CT7-9C, and CT7-9C3 engines. AD 2018-03-13 required initial and repetitive visual inspections and fluorescent penetrant inspections (FPIs) of the main propeller shaft. This AD was prompted by an in-flight failure of a main propeller shaft on a GE Model CT7-9B engine, resulting in the loss of the propeller. This AD requires initial and repetitive visual inspections, FPIs, and ultrasonic inspections (USIs) of the main propeller shaft. Depending on the results of these inspections, this AD requires replacement of the main propeller shaft. As an optional terminating action to these inspections, this AD requires revising the airworthiness limitations section (ALS) of the existing maintenance manual (MM) and the operator's existing approved maintenance program or inspection program, as applicable, to incorporate incorporating the tasks and reduced inspection thresholds for the main propeller shaft. The FAA is issuing this AD to address the unsafe condition on these products.

This action proposes to amend the Class E airspace at Hutchinson, MN. The FAA is proposing this action as the result of an airspace review conducted due to the decommissioning of the Darwin very high frequency omnidirectional range (VOR) as part of the VOR Minimum Operating Network (MON) Program. The name of the airport would also be updated to coincide with the FAA's aeronautical database. This action will bring the airspace into compliance with FAA orders to support instrument flight rule (IFR) operations.

This action proposes to amend the Class E airspace at Natchez, MS. The FAA is proposing this action as the result of an airspace review conducted due to the decommissioning of the Natchez very high frequency omnidirectional range (VOR) as part of the VOR Minimum Operating Network (MON) Program. The name and geographic coordinates of the airport would also be updated to coincide with the FAA's aeronautical database. This action will bring the airspace into compliance with FAA orders to support instrument flight rule (IFR) operations.

This action proposes to amend the Class E airspace at Jackson, OH. The FAA is proposing this action as the result of an airspace review conducted due to the decommissioning of the York very high frequency omnidirectional range (VOR) as part of the VOR Minimum Operating Network (MON) Program. The geographic coordinates of the airport would also be updated to coincide with the FAA's aeronautical database. This action will bring the airspace into compliance with FAA orders to support instrument flight rule (IFR) operations.

This amendment adopts miscellaneous amendments to the required IFR (instrument flight rules) altitudes and changeover points for certain Federal airways, jet routes, or direct routes for which a minimum or maximum en route authorized IFR altitude is prescribed. This regulatory action is needed because of changes occurring in the National Airspace System. These changes are designed to provide for the safe and efficient use of the navigable airspace under instrument conditions in the affected areas.
