Federal Aviation Administration December 23, 2024 – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Model EC225LP helicopters. This proposed AD was prompted by the identification of missing electrical bonding on a certain part-numbered additional and optional search light (search light). This proposed AD would require installing an electrical bonding braid modification and prohibit installing that part-numbered search light unless the modification is done. These actions are specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2023-09-06, which applies to all CFM International, S.A. Model (CFM) LEAP-1A23, LEAP-1A24, LEAP-1A24E1, LEAP-1A26, LEAP-1A26CJ, LEAP-1A26E1, LEAP-1A29, LEAP-1A29CJ, LEAP-1A30, LEAP-1A32, LEAP-1A33, LEAP-1A33B2, and LEAP-1A35A (LEAP-1A) engines. AD 2023-09-06 requires replacement of certain high-pressure turbine (HPT) rotor stage 1 disks (HPT stage 1 disks), forward outer seals, and compressor rotor stages 6-10 spools. AD 2023-09-06 also prohibits installation of an HPT stage 1 disk, forward outer seal, or compressor rotor stages 6-10 spool that has a part number and serial number identified in the service information onto any engine. Since the FAA issued AD 2023-09-06, the manufacturer identified additional affected parts that were manufactured from material suspected to have reduced material properties due to iron inclusion, which prompted this AD. This proposed AD would retain the requirements to replace certain HPT stage 1 disks, forward outer seals, and compressor rotor stages 6-10 spools and expand the applicability to include additional affected parts manufactured from the same material suspected to have reduced material properties due to iron inclusion. The FAA is proposing this AD to address the unsafe condition on these products.

This action modifies the Class D airspace and Class E airspace designated as a surface area and revokes the Class E airspace designated as an extension to the Class D or Class E surface area at Buckley Space Force Base, Aurora, CO. Additionally, this action modifies the administrative portions of the airport's legal descriptions to match the FAA's database. These actions will support the safety and management of instrument flight rules (IFR) and visual flight rules (VFR) operations at the airport.

This action modifies the Class D airspace, Class E airspace area designated as a surface area (Class E2 surface area), and Class E airspace area extending upward from 700 feet or more above the surface of the earth (Class E5 airspace area) at Camp Guernsey Airport, Guernsey, WY. This modification supports the containment of instrument flight rules (IFR) operations at the airport. Additionally, this action updates the administrative caption of the airport's legal descriptions.
