✈️Amendment of Class E Airspace Regulations in Marysville, OH
This action amends the Class E airspace at Marysville, OH. This action is the result of an airspace review conducted due to the decommissioning of the Marysville nondirectional beacon (NDB). The geographic coordinates are being corrected due to a typographical error and updated to coincide with the FAA's aeronautical database. This action brings the airspace into compliance with FAA orders and supports instrument flight rule (IFR) procedures and operations.

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -216, -231, -232, and - 233 airplanes; and Model A321-211, -212, -213, -231, and -232 airplanes. This proposed AD was prompted by a report that cracks were found following fatigue tests for the new lower wing cover material on airplanes equipped with sharklets. This proposed AD would require repetitive inspections for discrepancies, and corrective action, 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🚁FAA Special Conditions for Airbus EC175B Helicopter
These special conditions are issued for the Airbus Helicopters (Airbus) Model EC175B helicopter. This model helicopter will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category helicopters. This design feature is a 30-minute all engines operating (AEO) power rating. This rating will be used for hovering at increased power for search and rescue missions. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

The FAA is superseding Airworthiness Directive (AD) 2020-20-17 and AD 2021-15-05 for all General Electric Company (GE) Model GE90- 110B1 and GE90-115B engines. AD 2020-20-17 prohibits dispatch of an airplane if certain status messages are displayed on the engine indicating and crew alerting system (EICAS) and if certain conditions are present; and as terminating action, requires revision of the existing FAA-approved minimum equipment list (MEL) by incorporating the dispatch restrictions into the MEL. AD 2021-15-05 requires initial and repetitive replacement of the full authority digital engine control (FADEC) integrated circuit (MN4) microprocessor. Since the FAA issued AD 2020-20-17 and AD 2021-15-05, the manufacturer has developed a software revision for the electronic engine control (EEC) FADEC that further mitigates the unsafe condition. This AD retains all the actions of AD 2020-20-17 and AD 2021-15-05, and also requires upgrading the EEC FADEC software to an EEC FADEC software version eligible for installation as a terminating action. 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 all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This proposed AD was prompted by a report of under-torqued and missing nuts on the horizontal stabilizer trim actuator (HSTA) lower gimbal assembly. This proposed AD would require a review of maintenance records to determine if an overhauled HSTA was inspected and corrective actions were accomplished using certain service information, and applicable on-condition actions. 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 all Airbus Helicopters Model EC120B, EC130B4, and EC130T2 helicopters. This proposed AD was prompted by a report of a missing retaining ring between the supply hose and the central supply coupling of an emergency floatation system (EFS) inflation assembly. This proposed AD would require inspecting for the presence of the retaining ring in an EFS with certain inflation assemblies installed and, depending on the results, taking corrective action. This proposed AD would also prohibit installing an EFS with those inflation assemblies installed. These actions are specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Learn More🚁Proposed Airworthiness Directive for Airbus Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model AS-365N2, AS 365 N3, EC 155B, EC155B1, SA-365N, and SA-365N1 helicopters. This proposed AD was prompted by reports of loss of tightening torque between the upper ball bearing end and the main rotor (MR) servo-control. This proposed AD would require inspecting the tightening torque and, depending on the results, taking corrective action. This proposed AD would also require reporting information. These actions are specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Learn More✈️Proposed FAA Airworthiness Directive for MHI RJ Aviation Aircraft
The FAA proposes to adopt a new airworthiness directive (AD) for all MHI RJ Aviation ULC Model CL-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-2C11 (Regional Jet Series 550), Model CL-600-2D15 (Regional Jet Series 705), CL-600-2D24 (Regional Jet Series 900), and CL-600-2E25 (Regional Jet Series 1000). This proposed AD was prompted by an engine indicating and crew alerting system (EICAS) STAB TRIM Caution message that was posted, and subsequent repair that found prematurely worn teeth on a rubber bull gear (RBG) wheel in the horizontal stabilizer trim actuator (HSTA). This proposed AD would require an inspection for part numbers and on-condition replacement of affected RBG wheels and prohibit the installation of affected parts under certain conditions, as specified in a Transport Canada 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✈️Proposed Airworthiness Directive for CFM International Engines
The FAA proposes to supersede Airworthiness Directive (AD) 2023-23-12, which applies to all CFM International, S.A. (CFM) Model LEAP-1B21, LEAP-1B23, LEAP-1B25, LEAP-1B27, LEAP-1B28, LEAP-1B28B1, LEAP-1B28B2, LEAP-1B28B2C, LEAP-1B28B3, LEAP-1B28BBJ1, and LEAP- 1B28BBJ2 (LEAP-1B) engines. AD 2023-23-12 requires replacing certain high-pressure turbine (HPT) rotor stage 1 disks and a certain compressor rotor stages 6-10 spool. Since the FAA issued AD 2023-23-12, the manufacturer has identified additional parts that were manufactured from material suspected to have reduced material properties due to iron inclusion, which prompted this proposed AD. This proposed AD would retain the requirements to replace certain HPT rotor stage 1 disks and a certain compressor rotor stages 6-10 spool. This proposed AD would also expand the applicability to include additional affected HPT rotor stage 1 disks that were manufactured from the same material suspected to have reduced material properties due to iron inclusion. The FAA is proposing this AD to address the unsafe condition on these products.
