The Federal Aviation Administration (FAA) has issued a new rule that updates and replaces a previous directive concerning the safety of certain airplane and helicopter seatbelt buckles. This change is in response to new information about manufacturing issues that could cause buckles to crack, potentially preventing passengers from unbuckling during an emergency. The rule requires inspections of these buckles, provides guidance for corrective actions, and includes exemption criteria such as buckles made of metal or marked with a blue logo. This action aims to ensure passenger safety by addressing weaknesses in the affected buckle systems.

The Federal Aviation Administration (FAA) is issuing a final rule to update airworthiness directives for Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. This rule replaces a previous directive due to the discovery of a new airworthiness limitation, which involves regular inspections and maintenance to address potential sand contamination and corrosion in the elevator torque tube bearings. These measures are intended to prevent possible binding or seizure of these components, which could lead to a loss of pitch control. The rule also provides guidelines for compliance and specifies that existing maintenance programs must be updated by March 11, 2025, to incorporate these new requirements.

The Federal Aviation Administration (FAA) has issued a new rule for several models of Airbus Helicopters due to reports of accidental activation of a crucial button during a night flight. This directive requires helicopter operators to check the safety mechanism of the button on the pilot's controls and replace certain parts if necessary to prevent potential hazards. It applies to specific helicopter models and mandates regular inspections every 12 months. The rule is effective from March 7, 2025, and includes provisions for owners to conduct some checks themselves if they possess the necessary certification.

The Environmental Protection Agency (EPA) has issued new rules under the Toxic Substances Control Act (TSCA) for certain chemical substances identified in premanufacture notices (PMNs). These rules, known as Significant New Use Rules (SNURs), require companies to notify the EPA 90 days before beginning to manufacture or process these chemicals in ways considered a "significant new use," giving the EPA time to evaluate potential risks. The rules include specific requirements for workplace safety, such as ventilation and protective equipment, as well as guidelines for hazard communication. This regulation aims to prevent risks to human health and the environment before these new uses of chemicals are fully developed or used commercially.

The Department of State has issued a final rule that updates the criteria for issuing "diplomatic type" or "official type" visas, aiming to better align with U.S. laws and international travel practices. This rule expands the previous definition of passports by including non-national travel documents, such as those from organizations like the United Nations, as potential equivalents to diplomatic passports. It also clarifies the categories of individuals who can receive these visas, making distinctions to avoid confusion between visa types and classifications. These changes ensure that the visa issuance process for diplomatic, official, and regular types is consistent and transparent.

The FAA has issued a new airworthiness directive (AD) for Boeing 727 airplanes due to risks caused by excessive sealant on wing parts, which might hide cracks during inspections. This rule mandates changes to maintenance or inspection programs to ensure the required damage tolerance rating and repetitive inspections of certain wing parts to detect potential issues. Effective March 31, 2021, this AD aims to prevent possible structural failures that could lead to loss of control of the aircraft. The directive includes compliance procedures, costs, and the regulatory rationale behind these safety measures.

The Environmental Protection Agency (EPA) is proposing new rules for the use of certain chemical substances under the Toxic Substances Control Act (TSCA). These rules, known as Significant New Use Rules (SNURs), require entities to notify EPA at least 90 days before starting activities considered significant new uses of these chemicals. The EPA will then assess these uses for potential risks. The proposed rules aim to ensure new chemical substances are safely manufactured and processed, protecting human health and the environment.

The document details final regulations that implement clean electricity production and investment credits established by the Inflation Reduction Act of 2022. These regulations provide guidelines for determining greenhouse gas emissions from electricity production, setting provisional emissions rates, and determining eligibility for the tax credits.
