Federal Aviation Administration March 15, 2024 – Federal Register Recent Federal Regulation Documents

The FAA is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) Model CT7-2E1, CT7-2F1, CT7-8A, CT7-8E, CT7-8F5 engines, and various restricted category helicopters with GE Model T700-GE-700,-701A, -701C, -701D/CC, -701D, -401, -401C, CT7-2D or CT7-2D1 engines installed. This AD was prompted by at least four reports of failures of the torque reference tube magnetic insert braze joint of the power turbine drive shaft assembly within the last several months. This AD requires a phase array ultrasonic inspection of the torque reference tube magnetic insert braze joint of the power turbine drive shaft assembly for inadequate braze coverage, and repair or replacement of the power turbine drive shaft assembly if necessary. The FAA previously sent an emergency AD to all known U.S. owners and operators of these engines and helicopters and is now issuing this AD to address the unsafe condition on these products.

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

This action proposes amending Class D airspace extending upward from the surface for Simmons Army Air Field, Fort Liberty, NC, updating the geographic coordinates, and amending verbiage in the description.

The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A318, A319, A320, and A321 series 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, 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.

This action modifies the Class E airspace extending upward from 700 feet above the surface and removes the Class E airspace extending upward from 1,200 feet above the surface at Klawock Airport, Klawock, AK. Additionally, this action updates the administrative portion of the airport's existing Class E airspace legal description. These modifications support the safety and management of instrument flight rules (IFR) operations at the airport.
