🌍EPA Proposes Air Plan Approval for Ortho Clinical Diagnostics
The Environmental Protection Agency (EPA) is proposing to approve a revision to the State of New York's State Implementation Plan (SIP) for the ozone National Ambient Air Quality Standard (NAAQS) related to a source-specific SIP (SSSIP) revision for Ortho Clinical Diagnostics, 513 Technology Boulevard, Rochester, New York (the Facility). The EPA is proposing to find that the control options in this SSSIP revision implement Reasonably Available Control Technology (RACT) with respect to volatile organic compound (VOC) emissions from the relevant Facility source, which are identified as one solvent-based film coating machine. This SSSIP revision is intended to implement VOC RACT for the relevant Facility source in accordance with the requirements for implementation of the 2008 and 2015 ozone NAAQS. EPA proposes to determine that this action will not interfere with ozone NAAQS requirements and meets all applicable requirements of the Clean Air Act (CAA).

The Environmental Protection Agency (EPA) is approving a state implementation plan (SIP) revision submitted by the State of Maryland. This revision (Maryland Submittal #24-01) pertains to the re-allocation of nitrogen oxides (NO<INF>X</INF>) ozone season emission caps for large non-electric generating units (non-EGUs, affected units). The amendment also updates a cross reference to the Cross State Air Pollution Rule (CSAPR). This action is being taken under the Clean Air Act (CAA).

The Environmental Protection Agency (EPA) is approving the Commonwealth of Pennsylvania's request to redesignate to attainment the Liberty-Clairton, Pennsylvania nonattainment area (Liberty-Clairton Area) for the 1997 annual and 2006 24-hour fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standards (NAAQS or standard). The EPA has determined that the Liberty-Clairton Area attained both the 1997 annual and 2006 24-hour PM<INF>2.5</INF> NAAQS and has met the statutory requirements for redesignation. The EPA is approving, as a revision to the Pennsylvania State Implementation Plan (SIP), the Commonwealth's plan for maintaining the 1997 annual and 2006 24-hour PM<INF>2.5</INF> NAAQS through 2035 for the Liberty-Clairton Area. Additionally, the EPA is approving the maintenance plan for the Allegheny County, Pennsylvania nonattainment area (Allegheny County Area) for the 2012 annual PM<INF>2.5</INF> NAAQS through 2035. The maintenance plan includes 2017, 2026, and 2035 mobile vehicle emissions budgets (MVEBs) for mobile sources of PM<INF>2.5</INF> and nitrogen oxides (NO<INF>X</INF>) for the Allegheny County Area for the 2012 annual PM<INF>2.5</INF> NAAQS, which the EPA is approving for transportation conformity purposes. This action does not redesignate the Allegheny County Area to attainment for the 2012 annual PM<INF>2.5</INF> NAAQS. Both the redesignation request and maintenance plan were submitted by the Commonwealth of Pennsylvania Department of Environmental Protection (PADEP or Pennsylvania) on behalf of the Allegheny County Health Department (ACHD). This action is being taken under the CAA.
Learn More✈️Proposed Airworthiness Directive for Boeing 767 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 767-200 and 767-300 series airplanes. This proposed AD was prompted by reports of scribe lines found at skin lap joints and butt joints, around external repairs and antennas, and at locations where external decals had been cut. For some airplanes, this proposed AD would require a detailed inspection for scribe lines and applicable related investigative and corrective actions. For other airplanes, this AD would require repetitive nondestructive testing inspections for cracking at certain stringers of the skin lap joint fuselage skin and applicable corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
Learn More✈️Proposed Airworthiness Directive for Boeing 737-800 Airplanes
The FAA proposes to supersede Airworthiness Directive (AD) 2013-08-15, which applies to certain The Boeing Company Model 737-800 series airplanes. AD 2013-08-15 requires repetitive inspections for cracking of the fuselage skin along chem-mill steps at certain crown skin and shear wrinkle areas and repair if necessary. Since the FAA issued AD 2013-08-15, the FAA has determined that the compliance times are not adequate. This proposed AD would continue to require the actions in AD 2013-08-15 but at reduced compliance times and would require post-modification inspections if an optional terminating action is accomplished. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Schempp-Hirth Flugzeugbau GmbH (Schempp-Hirth) Model CIRRUS gliders. This proposed AD was prompted by reports of a broken outer race of the lower ball bearing installed in the all-moving horizontal tailplane drive fitting. This proposed AD would require inspecting the elevator drive fitting to determine the type of lower ball bearing installed, and depending upon the results, replacing the lower ball bearing with a serviceable part. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS 365 N3, EC 155B, and EC155B1 helicopters. This AD was prompted by reports of false engine fire warnings. This AD requires replacing affected engine fire detectors and prohibits installing an affected engine fire detector or an engine that contains an affected engine fire detector. The FAA is issuing this AD to address the unsafe condition on these products.
Learn More✈️FAA Airworthiness Directive for BRP-Rotax Engines - 2025
The FAA is superseding Airworthiness Directive (AD) 2025-07- 02, which applied to certain BRP-Rotax GmbH & Co KG (Rotax) Model 912 iSc2 Sport, 912 iSc3 Sport, 915 iSc2 C24, and 915 iSc3 C24 engines. AD 2025-07-02 required repetitive operational checks of the battery backup function with removal of the engine from service if insufficient battery power is found, one-time inspections of the oil spray nozzle and generator stator assembly, and, depending on the results of the inspections, replacement with parts eligible for installation. Since the FAA issued AD 2025-07-02, the FAA has determined that the inspection of the generator stator assembly should be an on-condition action depending on the results of the oil spray nozzle inspection. This AD retains all of the requirements of AD 2025-07-02 and changes the one-time inspection of the generator stator assembly and wiring to an on-condition action based on the results of the one-time inspection of the oil spray nozzle. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Model AS 350B2, AS 350B3, AS355N, AS355NP, and EC 130 B4 helicopters. This proposed AD was prompted by a report of a loss of cargo load during cargo swing operation on a helicopter due to an incorrect adjustment of the release cable of the cargo swing emergency release control. This proposed AD would require a one-time inspection of the cargo swing emergency release control and, depending on the results, corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
