The FAA is superseding Airworthiness Directive (AD) 2021-25-03 for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent 7000-72 and Trent 7000-72C engines. AD 2021-25-03 required operators to revise the airworthiness limitation section (ALS) of their existing approved continuous airworthiness maintenance program by incorporating the revised tasks of the applicable time limits manual (TLM) for each affected engine model. Since the FAA issued AD 2021-25-03, the manufacturer again revised the TLM to introduce new or more restrictive tasks and limitations and associated thresholds and intervals for life- limited parts, which prompted this AD. This AD requires revising the ALS of the operator's existing approved engine maintenance or inspection program, as applicable, to incorporate new or more restrictive tasks and limitations and associated thresholds and intervals for life-limited parts, 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.

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval a new information collection. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on June 12, 2023. The FAA proposes collecting information related to requests for certificate of waivers made to operate Unmanned Aircraft Systems (UAS) in deviation from the normal operating rules. The list of rules subject to waiver requests is found in the Code of Federal Regulations. The FAA will use the collected information to make determinations whether to authorize or deny the requested operation of UAS. The proposed information collection is necessary to issue such authorizations or denials consistent with the FAA's mandate to ensure safe and efficient use of national airspace.

The FAA proposes to supersede Airworthiness Directive (AD) 2021-22-05, which applies to all Leonardo S.p.a. (Leonardo) Model A119 and AW119 MKII helicopters. AD 2021-22-05 requires repetitively inspecting certain torque tube assemblies for any deficiency and corrective action if necessary, and replacing any affected part with a serviceable part, which is terminating action for the repetitive inspections. AD 2021-22-05 was prompted by reports of abnormal play on the collective torque tube on two Leonardo Model AW119 MKII helicopters, which were due to an erroneous manufacturing process. Since the FAA issued AD 2021-22-05, it was discovered that additional torque tube assemblies are subject to the unsafe condition. This proposed AD would retain certain requirements specified in AD 2021-22- 05, reduce the applicability to include helicopters with only affected part-numbered collective torque tube assemblies, reduce the inspection intervals, and remove the previously approved terminating action as 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 adopt a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes.

This proposed AD would require replacement of affected EBAS T-Ducts and limit the installation of affected parts under certain conditions, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

This notice announces a meeting of the COMSTAC.

The FAA proposes to supersede Airworthiness Directive (AD) 2021-07-13, which applies to certain Pacific Scientific Company rotary buckle assemblies (buckles). AD 2021-07-13 requires inspecting each buckle including its buckle handle vane, and depending on the results, removing the buckle from service and installing an airworthy buckle. AD 2021-07-13 also prohibits installing affected buckles. Since the FAA issued AD 2021-07-13, the manufacturer published an updated service bulletin, which revises the applicability based on date of manufacture of the affected buckles. This proposed AD would retain certain requirements of AD 2021-07-13. This proposed AD would also reduce the applicability to plastic buckles manufactured on or before May 31, 2007, or any buckle assembly whose date of manufacture cannot be determined. Additionally, this proposed AD would require performing corrective actions by complying with certain portions of the updated service bulletin. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for certain MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This proposed AD was prompted by a determination that the overhead bin attachment could fail under certain conditions. This proposed AD would require replacing existing overhead bin hook assemblies and support tubes with a different type, as specified in a Transport Canada AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.a. Model AW189 helicopters.

This AD requires borescope inspections (BSIs) of the HPC stage 1 and stage 2 rotor path liners for material loss, 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 is superseding airworthiness directive (AD) 2024-05- 51, which applied to certain General Electric Company (GE) Model CT7- 2E1, CT7-2F1, CT7-8A, CT7-8E, and 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. AD 2024-05-51 required a phase array ultrasonic inspection of the torque reference tube magnetic insert braze joint of the power turbine (PT) drive shaft assembly for inadequate braze coverage, and repair or replacement of the PT drive shaft assembly if necessary. This AD was prompted by at least four reports of failures of the torque reference tube magnetic insert braze joint of the PT drive shaft assembly within the last several months. This AD retains the requirements of AD 2024-05-51 and expands the applicability to include a PT drive shaft assembly part number that was inadvertently omitted. 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 rule establishes, amends, suspends, or removes Standard Instrument Approach Procedures (SIAPS) and associated Takeoff Minimums and Obstacle Departure procedures (ODPs) for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

This action amends Class D airspace, Class E surface airspace, and Class E airspace extending upward from 700 feet above the surface for Wallops Flight Facility, Wallops Island, VA.
