🌍Proposed Rule for Ozone Attainment Date Extension in Coachella Valley
The Environmental Protection Agency (EPA) is proposing to grant a one-year extension of the "Extreme" attainment date for the 1997 ozone national ambient air quality standards (NAAQS) to the Riverside County (Coachella Valley) ozone nonattainment area ("Coachella Valley"). This action is based on the EPA's evaluation of air quality monitoring data and the extension request submitted by the State of California. We are taking comments on this proposal and plan to follow with a final action.

The FAA is superseding Airworthiness Directive (AD) 2019-05- 02, which applied to certain Rolls-Royce Deutschland Ltd & Co KG (RRD) (type certificate previously held by Rolls-Royce plc) Model RB211-Trent 970-84 and RB211-Trent 972-84 engines. AD 2019-05-02 required repetitive inspections of the drains mast for any crack and replacement or repair of the drains mast if necessary. Since the FAA issued AD 2019-05-02, the manufacturer has developed a modification (improved drains mast and drains support bracket), which the FAA has determined mitigates the unsafe condition. This AD was prompted by cracks found in the transition duct area of the drains mast. This AD requires modification with improved drains mast and drains support bracket. 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 The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by reports of multiple nonconformances, including excessive gaps and pull-up, found during the assembly and installation of the forward pressure bulkhead. This proposed AD would require an internal and external detailed inspection (DET) of the forward pressure bulkhead (FPB) for any damage and performing applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2022-27-01, which applies to certain Airbus SAS Model A350-941 and - 1041 airplanes. AD 2022-27-01 requires replacing affected fasteners and applying additional head nut cap protection at the front and rear spars in the center wing box (CWB). Since the FAA issued AD 2022-27-01, the FAA determined that additional Airbus SAS Model A350 manufacturer serial numbers (MSNs) are affected by the same potential unsafe condition. This proposed AD would continue to require the actions in AD 2022-27-01 and would expand the applicability to include the additional Airbus SAS Model A350 MSNs, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
Learn More✈️New Airworthiness Directive for GE Engines Affects Compliance and Costs
The FAA is adopting a new airworthiness directive (AD) for all General Electric Company (GE) Model CT7-2E1 engines. This AD was prompted by a revised analysis using an updated stress model, which calculated that the actual life limit of the CT7-2E1 stage 2 turbine aft cooling plate is less than the current life limit. This AD requires revision of the airworthiness limitations section (ALS) of the existing CT7-2E1 engine maintenance manual (EMM) and the operator's existing approved maintenance program or inspection program, as applicable, to incorporate a reduced life limit for this part. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2024-06-06 for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent7000-72 and Trent7000-72C engines. AD 2024-06-06 required revising the airworthiness limitations section (ALS) of the operator's existing approved engine maintenance or inspection program, as applicable, to incorporate new or more restrictive tasks and limitations and associated thresholds and intervals for life-limited parts. Since the FAA issued AD 2024-06-06, the manufacturer has revised the engine time limits manual (TLM) to introduce new or more restrictive tasks and limitations and associated thresholds and intervals for life-limited parts, which prompted this AD. This AD requires revising the ALS of the existing approved engine maintenance or inspection program, as applicable, to incorporate new or more restrictive tasks and limitations and associated thresholds and intervals for life-limited parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Learn More✈️Proposed AD for Safran Helicopter Engines Raises Compliance Costs
The FAA proposes to adopt a new airworthiness directive (AD) for all Safran Helicopter Engines, S.A. (Safran) Model ARRIUS 2F and ARRIUS 2R engines. This proposed AD was prompted by a manufacturer investigation that revealed certain high-pressure (HP) turbine blades may contain non-compliant porosity rates due to a change in the manufacturing process. This proposed AD would require replacement of affected HP turbine blades, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Learn More✈️Proposed Airworthiness Directive for Airbus SAS Airplanes by FAA
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A300 B4-2C, A300 B4-203, A300 B4-603, A300 B4-605R, A300 B4-622, A300 B4-622R, and A300 F4-605R airplanes. This proposed AD was prompted by reports of cracking of the main landing gear (MLG) support rib 5 lower flange on certain modified airplanes due to incorrect accomplishment of modification instructions. This proposed AD would require a special detailed inspection (geometrical inspection) of the MLG rib 5 lower flange holes on the left-hand wing and right- hand wing and repair if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
Learn More✈️New Airworthiness Directives Impacting De Havilland Aircraft
The FAA is superseding Airworthiness Directive (AD) 2022-01- 02, which applied to certain De Havilland Aircraft of Canada Limited Model DHC-8-400, -401, and -402 airplanes. AD 2022-01-02 required inspecting for corrosion of the nacelle to wing rear spar attachment pins, and the nacelle to landing gear attachment pins, and doing all applicable corrective actions. This AD was prompted by a determination that some operators were unable to identify the airplanes subject to each requirement. This AD continues to require the actions specified in AD 2022-01-02, clarifies the affected airplanes for each required action, and revises the applicability by removing Model DHC-8-400 airplanes; as specified in Transport Canada AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
