Open for Comment: Airworthiness Directives; Hélicoptères Guimbal Helicopters

By CIV.IQ May 7, 2026
Transportation Department — The FAA proposes to adopt a new airworthiness directive (AD) for certain H[eacute]licopt[egrave]res Guimbal (HG) Model Cabri G2 helicopters. This proposed AD was prompted by a report of a potential malfunction of the helicopter emergency locator transmitter (ELT) and subsequent findings of weak ELT signals on 121.5 MHz and 406 MHz frequencies due to improper antenna installation (location). This proposed AD would require revising the existing rotorcraft flight manual (RFM) for the helicopter. The FAA is proposing this AD to address the unsafe condition on these products.

Open for Comment: Airworthiness Directives; Airbus Helicopters

Transportation Department — The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model EC 155B and EC155B1 helicopters. This proposed AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the airworthiness limitations section (ALS) of the existing maintenance manual (MM) or instructions for continued airworthiness and the existing approved maintenance or inspection program, as applicable. The FAA is proposing this AD to address the unsafe condition on these products. (46 days remaining)

Open for Comment: Air Plan Approval; Missouri; Attainment Plan for the New Madrid Nonattainment Area for the 2010 1-Hour Sulfur Dioxide National Ambient Air Quality Standard

Environmental Protection Agency — The Environmental Protection Agency (EPA) is proposing to approve the State Implementation Plan (SIP) revision, submitted by the State of Missouri, on May 3, 2023. This revision pertains to the attainment plan for the New Madrid nonattainment area for the 2010 1- hour sulfur dioxide (SO<INF>2</INF>) primary National Ambient Air Quality Standard (NAAQS). This plan (herein called an "attainment plan") includes the State's attainment demonstration and other elements required under Clean Air Act (CAA). In addition to an attainment demonstration, the plan addresses emission limitations necessary to provide for attainment, base-year and projection-year emission inventories, reasonably available control measures and reasonably available control technology (RACM/RACT), nonattainment new source review (NNSR), the requirements for meeting reasonable further progress (RFP) toward attainment of the NAAQS, and contingency measures. The EPA is proposing to approve Missouri's submission as meeting these relevant CAA requirements. This action is being taken pursuant to the CAA. (32 days remaining)

Open for Comment: Atlantic Highly Migratory Species; North Atlantic Swordfish, South Atlantic Swordfish, North Atlantic Albacore, and Atlantic Bluefin Tuna Quotas

Commerce Department — NMFS is proposing to implement recent binding recommendations of the International Commission for the Conservation of Atlantic Tunas (ICCAT) on quotas for North Atlantic swordfish, South Atlantic swordfish, North Atlantic albacore tuna (northern albacore), and Atlantic bluefin tuna. While this action does not propose to change the existing baseline quotas for North Atlantic swordfish, South Atlantic swordfish, and northern albacore, this action proposes to implement the management procedure for North Atlantic swordfish, describes the existing management procedure for northern albacore, and considers the possibility of future quota changes for swordfish and northern albacore consistent with their respective management procedures and ICCAT recommendations. For bluefin tuna, this action also proposes to implement the increased U.S. baseline quota adopted by ICCAT in 2025, divide it among the established regulatory domestic subquota categories, and implement changes to the bluefin tuna quota associated with longline bycatch adopted by ICCAT in 2025. This proposed rule also describes the annual quota adjustment procedures for North Atlantic swordfish, South Atlantic swordfish, northern albacore, and bluefin tuna and requests public comment on them. This action is required by the Atlantic Tunas Convention Act (ATCA) and to achieve domestic management objectives under the Magnuson-Stevens Fishery Conservation and Management Act (Magnuson-Stevens Act).
