The National Highway Traffic Safety Administration (NHTSA) has delayed the effective date of a new safety rule, FMVSS No. 305a, from December 20, 2024, to March 20, 2025. This rule is meant to update safety standards for electric vehicles, focusing on aspects like battery safety and emergency response information. The delay allows for further review as directed by a presidential memorandum, aiming to ensure all new regulations are thoroughly considered. Public comments are not being solicited for this delay because it was deemed urgent and necessary for the smooth implementation of the regulations.

The U.S. International Trade Commission has started an investigation based on a complaint from Credo Semiconductor Inc. and Credo Technology Group Ltd. The complaint, filed in March and amended in April 2025, alleges that certain companies are importing electrical cables into the U.S. that infringe on specific patents held by Credo. The companies named in the complaint include Amphenol Corporation, Molex, LLC, and TE Connectivity PLC. The Commission will explore whether these imports violate section 337 of the Tariff Act of 1930 and will potentially issue orders to halt their importation if patent infringements are confirmed.

The Mine Safety and Health Administration (MSHA) received a request for a change in safety rules from the 3M Company. They want to alter the current regulation that affects the use of compressed air for cleaning dust off miners' clothing at their Corona Plant in California. The proposed method involves using a special booth and equipment that the National Institute for Occupational Safety and Health (NIOSH) has tested and approved as safe. The complete details of the proposal, including safety measures and training plans, are open for public comment until May 19, 2025.

The Mine Safety and Health Administration (MSHA) has issued a notice regarding a petition for modification submitted by Harrison County Coal Resources, Inc. The company seeks to change the existing safety standards by increasing the allowed length of certain electrical cables used in the Harrison County Mine. They argue that their proposed alternative methods provide equal or greater safety measures as compared to current standards. If granted, this modification would apply to trailing cables providing power to mining equipment, ensuring safety through specific conditions and training requirements.

The Federal Aviation Administration (FAA) has issued a new airworthiness directive (AD) for certain models of Airbus Helicopters. This directive aims to improve safety by requiring the replacement of existing magnetic plugs in the main gear box with improved non-electrical magnetic plugs. These changes were prompted by the need to better collect metal particles, which could otherwise lead to the seizure of the main gear box and cause a loss of helicopter control. The directive, which becomes effective on April 1, 2021, references an AD from the European Union Aviation Safety Agency and provides guidelines for compliance.

The Federal Aviation Administration (FAA) has issued a final rule concerning Airbus Helicopters Model AS350B3. This rule mandates upgrades to the electrical system for the throttle twist grip and inspections of a microswitch electrical harness to prevent potential engine issues where helicopters could remain in idle mode unintentionally. The rule, prompted by similar European regulations, aims to ensure safety and requires compliance by a specific date or service hours, with details available from Airbus Helicopters. The rule affects 517 helicopters and is meant to avoid jeopardizing flight safety and prevent accidents.

The Federal Aviation Administration (FAA) has issued special conditions for the Safran Electric & Power S.A. Model ENGINeUS 100A1 electric engines, which will serve as the primary propulsion systems in aircraft. These engines use novel electrical technology instead of traditional fuel-burning systems, necessitating the creation of new safety standards. The special conditions outline specific requirements for the engine's design, safety assessments, and operational capabilities to ensure equivalent safety levels to conventional engines. The document responds to public comments and incorporates changes based on feedback from various stakeholders, such as Airbus and Ampaire, emphasizing the safe integration of these electric engines in aviation.

The FAA has released special conditions for the certification of BETA Technologies Inc.'s Model H500A electric engines, which use an electric motor for aircraft propulsion. These engines have a unique design that doesn't fit existing safety standards, so new rules outline the safety requirements needed to ensure they are as safe as conventional engines. The rules include criteria for engine components like electrical systems, controls, and protection against overspeed and ingestion, among others. These conditions respond to comments from experts and aim to ensure these novel engines operate safely.

The U.S. Nuclear Regulatory Commission (NRC) has released a draft regulatory guide, DG-1303, for public comment, titled "Application and Testing of Safety-Related Diesel Generators in Nuclear Power." This guide, a revision of Regularity Guide 1.9, provides updated guidance for ensuring emergency power supplies in nuclear power plants meet safety regulations. The draft endorses certain IEEE standards to certify that these power supplies are reliable and capable during emergencies. The public can submit comments by February 18, 2021, through various channels detailed in the notice.

The Federal Aviation Administration (FAA) has issued a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd. Model PC-24 airplanes. This directive is a response to information about electrical harness installations that do not meet approved designs, which could cause issues like wire chafing, arcing, or failure. These problems might lead to loss of system redundancy or other safety hazards. To address this, the AD requires modifications to the electrical harness installations, which will cost about $1,775 per aircraft to implement.
