Open for Comment: Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Engines

By CIV.IQ June 1, 2026
Transportation Department — The FAA proposes to adopt a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211 Trent 768-60, 772-60, and 772B-60 engines. This proposed AD was prompted by a report that a batch of low-pressure compressor (LPC) blades were exposed to a non-conforming repair and are more prone to cracking due to a deviation from the approved blade configuration design. This proposed AD would require removal from service of the affected LPC blades and replacement with a serviceable part. The FAA is proposing this AD to address the unsafe condition on these products.

Open for Comment: Regulation for Federal Financial Assistance

Management and Budget Office — The Office of Management and Budget (OMB) proposes to revise the Guidance for Federal Financial Assistance to improve government- wide policies and requirements related to the management of grants, cooperative agreements, and other forms of assistance. OMB is proposing revisions that would improve transparency, accountability, and oversight for Federal awards across the Federal Government. This includes ensuring that American tax dollars are not wasted or misused, activities performed under Federal awards are consistent with law and policy, and recipients are held accountable when they fail to meet relevant standards. The revisions also aim to ensure that basic American principles of equality and equal opportunity are upheld throughout all stages of the award making process and that unlawful discrimination is no longer permitted. Proposed changes also include providing further clarification on the regulatory status of the OMB requirements and on the process for future updates to the government- wide requirements. Finally, OMB also proposes changes to reduce recipient burden. The listed Federal grant-making agencies propose conforming changes to their respective adopting regulations, or, in the case of some agencies and other entities, establishing new adopting regulations or policies. The proposed changes reflect the administration's commitment to transparency, accountability, and proper oversight for the Federal grantmaking process. The proposed regulations seek to ensure that American tax dollars are ultimately used to serve the needs of the American public. (45 days remaining)

Open for Comment: Air Plan Approval; Michigan; Determination of Attainment by the Attainment Date for the 2015 Ozone Standards

Environmental Protection Agency — The Environmental Protection Agency (EPA) is proposing to determine under the Clean Air Act (CAA) that the Detroit, Michigan nonattainment area ("Detroit area" or "area") attained the 2015 ozone National Ambient Air Quality Standards (NAAQS) by the applicable attainment date. This determination relies on the EPA's concurrence on an exceptional events request submitted by the Michigan Department of Environment, Great Lakes, and Energy (EGLE) on February 19, 2026, and concurred on by the EPA on March 24, 2026. Therefore, the EPA is proposing to take final agency action on Michigan's exceptional events request. This action, if finalized, will fulfill the EPA's statutory obligation to determine whether the Detroit area attained the 2015 ozone NAAQS by the Moderate attainment date of August 3, 2024.
