The U.S. Nuclear Regulatory Commission (NRC) is proposing a new rule to update its regulations by incorporating revisions to three regulatory guides related to Code Cases published by the American Society of Mechanical Engineers (ASME). These changes would provide new and updated engineering standards for nuclear power plant components, allowing licensees and applicants to use these standards as voluntary alternatives. The NRC is seeking public comments on this proposal, and if implemented, it is expected to reduce costs for both the NRC and the nuclear industry by simplifying compliance requirements. The aim is to ensure safety while aligning with contemporary engineering practices and international standards.

The Federal Aviation Administration (FAA) has issued a new rule replacing a previous Airworthiness Directive (AD) concerning specific models of Leonardo S.p.A. helicopters. This new AD requires ongoing inspections and maintenance of the tail rotor duplex bearing to ensure the safety and stability of the aircraft. The rule, effective April 1, 2021, anticipates monitoring for any unsafe conditions in these helicopters due to incorrect installations that could lead to loss of control. It sets forth clear procedures operators must follow to comply with these requirements, including removing specific parts if defects are found.

The FAA has issued a final airworthiness directive (AD) for certain Pilatus Aircraft Ltd. Model PC-12/47E airplanes to address a safety issue. The problem stems from inboard flap fairings with an incorrect shape, potentially leading to chafing with a tension rod, which could cause a failure in the flap system and reduce airplane control. The AD requires inspections of the affected parts to check for chafing and to ensure the correct shape; corrective actions must be taken if necessary. The rule applies to specific serial numbers and outlines inspection requirements, with expected compliance costs detailed.

The Bureau of Industry and Security (BIS) has issued a final rule amending the Export Administration Regulations (EAR) to align with recent decisions made by the Australia Group (AG), a multilateral forum focused on preventing the spread of chemical and biological weapons. These changes include new controls on instruments for peptide synthesis, dipropylamine, and neosaxitoxin, and adjustments to existing controls on botulinum toxins and toxic gas monitors. The rule is effective December 23, 2024, and reflects ongoing international efforts to enhance export controls on items that can potentially be used in weapons programs.

The Coast Guard is proposing a temporary safety zone in Corpus Christi Bay and the Corpus Christi Ship Channel during an airshow from April 29 to May 2, 2021. This is to ensure the safety of people and vessels on the water, and no vessel or person will be allowed in the safety zone without permission. The zone will be in effect from 11:30 a.m. to 4:30 p.m. each day of the event. The Coast Guard invites public comments on this proposal to help shape the outcome of the rulemaking.

The National Oceanic and Atmospheric Administration (NOAA) issued a final rule to establish harvest specifications and management measures for the 2025-26 Pacific Coast groundfish fishery. This rule sets limits on how much groundfish can be caught each year and revises management measures to prevent overfishing and help rebuild stock. Key changes include implementing a rebuilding plan for California quillback rockfish and updating allocation frameworks and fishing regulations. The rule also introduces a new permit system for the directed open access fishery and includes technical corrections and modifications to existing regulations.

The National Marine Fisheries Service (NMFS) proposes changes to the Pacific Halibut Catch Sharing Plan for Area 2A, which includes waters off Washington, Oregon, and California. These changes aim to manage recreational fisheries better and include adjustments to fishing seasons, allocations, and management measures. The proposed rule is intended to conserve the Pacific halibut while allowing for more angler opportunities. The public is invited to submit comments on this proposal by March 15, 2021.

The Federal Aviation Administration (FAA) is proposing a new airworthiness directive (AD) for certain General Electric engines used in airplanes. This action is due to concerns about a part called the combustion chamber assembly (CCA) which may fail sooner than expected. To prevent this, the FAA wants regular inspections and timely replacements of this component. They are seeking public comments on this proposal until February 10, 2025.

The Federal Aviation Administration (FAA) is proposing to update an existing Airworthiness Directive for Robinson Helicopter Company's R44 and R44 II models. This proposed rule aims to clarify inspections of certain parts due to potential fatigue cracking that could lead to loss of control. The FAA seeks public comments by March 17, 2025, and estimates the inspection and potential replacement efforts will impact 1,725 helicopters. The rule ensures the safety of these helicopters by improving maintenance procedures.

The Federal Aviation Administration (FAA) has issued a new airworthiness directive for Pilatus Model PC-24 airplanes. This directive was prompted by reports of cockpit and cabin evaporator filters with insufficient fire retardant properties being installed during production. These filters could cause a safety risk by increasing smoke in the cockpit and cabin if the electrical heater overheats. To address this issue, the directive requires replacement of these filters with new and properly manufactured ones. The rule becomes effective on March 30, 2021, and impacts certain Pilatus airplanes registered in the United States.
