Airworthiness Directives; Sikorsky Aircraft Corporation Helicopters
The FAA is adopting a new airworthiness directive (AD) for certain Sikorsky Aircraft Corporation Model S-92A helicopters. This AD was prompted by a cracked main rotor stationary swashplate assembly (swashplate assembly). This AD requires visually inspecting the swashplate assembly at specified intervals and depending on the results, removing the swashplate assembly from service. The FAA is issuing this AD to address the unsafe condition on these products.
Proposed Amendment of Class E Airspace; Elkton, MD
This action proposes to amend Class E airspace extending upward from 700 feet above the surface at Claremont Airport, Elkton, MD, as an airspace review found the airspace radius required an increase, as well as updating the airport's name. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.
Proposed Establishment of Area Navigation (RNAV) Route T-768; Northcentral United States
This action proposes to establish area navigation (RNAV) route T-768 in the northcentral United States (U.S.). The new T-768 would compensate for the removal of VOR Federal airway V-242 due to the decommissioning of the Atikokan, Ontario (ON), Canada, Non-Directional Beacon (NDB) navigational aid (NAVAID) as part of NAV CANADA's Airspace Modernization Program. The new T-768 in U.S. airspace would also connect to NAV CANADA's existing T-768 RNAV route to support cross border connectivity. Additionally, the new route would expand the availability of RNAV routing in support of transitioning the National Airspace System (NAS) from ground-based to satellite-based navigation.
Amendment, Establishment, and Revocation of Multiple Air Traffic Service (ATS) Routes in the Vicinity of Neosho, MO
This action amends Jet Route J-181 and VHF Omnidirectional Range (VOR) Federal airways V-13, V-14, V-15, and V-307; establishes Area Navigation (RNAV) routes T-411 and T-413; and removes VOR Federal airway V-506. The FAA is taking this action due to the planned decommissioning of the VOR portion of the Neosho, MO, VOR/Distance Measuring Equipment (VOR/DME) navigational aid (NAVAID). The Neosho VOR is being decommissioned in support of the FAA's VOR Minimum Operational Network (MON) program.
Amendment of VOR Federal Airways V-170, V-175 and V-250; Establishment of Area Navigation (RNAV) Route T-400; in the vicinity of Worthington, MN
This action amends VHF Omnidirectional Range (VOR) Federal airways V-170, V-175, and V-250; and establishes RNAV T-route T-400, in the vicinity of Worthington, Minnesota. This action is necessary due to the planned decommissioning of the VOR portion of the Worthington, MN, VOR/Distance Measuring Equipment (VOR/DME), which provides navigational guidance for these Air Traffic Service (ATS) routes. The Worthington VOR is being decommissioned as part of the FAA's VOR Minimum Operational Network (VOR MON) program.
Proposed Establishment of United States Area Navigation (RNAV) Route T-370; Kenai, AK
This action proposes to establish United States Area Navigation (RNAV) route T-370 in the vicinity of Kenai, AK in support of a large and comprehensive T-route modernization project for the state of Alaska.
Airworthiness Directives; Airbus Helicopters Deutschland GmbH Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH Model MBB-BK 117 D-3 helicopters. This proposed AD was prompted by reports of a main rotor (M/R) blade lead-lag damper in a tilted position. This proposed AD would require inspecting the Flex Control Unit (FCU), and corrective actions if necessary, as well as rework and re-identification of the bearing pin, 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.
Proposed Modification of Class E Airspace; Rifle Garfield County Airport, CO
This action proposes to modify the Class E airspace extending upward from 700 feet above the surface at Rifle Garfield County Airport, Rifle, CO. This action would ensure the safety and management of instrument flight rules (IFR) operations at the airport.
Amendment to Area Navigation (RNAV) T-302; Midwestern United States
This action amends RNAV route T-302 by extending it further to the east from its current endpoint. This action supplements the National Airspace System (NAS) enroute structure, as well as provides additional RNAV options in the Midwest. Additionally, this action supports the FAA's Next Generation (NextGen) Air Transportation System efforts to transition the NAS from ground-based to space-based navigation.
Amendment of V-37 and V-270; Removal of V-43 in the Vicinity of Erie, PA
This action amends VHF Omnidirectional Range (VOR) Federal airways V-37 and V-270, and removes VOR Federal airway V-43, in the vicinity of Erie, Pennsylvania. The airway amendments are necessary due to the planned decommissioning of the VOR portion of the Erie, PA, VOR/ Tactical Air Navigation (VORTAC), which provides navigational guidance for these airways. The Erie VOR is being decommissioned as part of the FAA's VOR Minimum Operational Network (MON) program.
Modification of Class E Airspace; Inyokern Airport, CA
This action modifies the Class E airspace at Inyokern Airport, Inyokern, CA. This action also proposes two administrative updates to the Class E5 text header. This action ensures the safety and management of instrument flight rule (IFR) operations at the airport.
Modification of Class D and Class E Airspace; China Lake NAWS (Armitage Field) Airport, CA
This action modifies the Class D airspace at China Lake NAWS (Armitage Field) Airport, China Lake, CA. This action also modifies the Class E airspace extending upward from 700 feet above the surface. Additionally, this action removes the China Lake (Navy) TACAN from the Class E5 text header and airspace description. Lastly, this action implements numerous administrative updates to the Class D and Class E5 text headers and the Class D airspace description. This action ensures the safety and management of instrument flight rule (IFR) operations at the airport.
Airworthiness Directives; Rolls-Royce Corporation Turboshaft Engines
The FAA proposes to supersede Airworthiness Directive (AD) 2017-18-14, which applies to certain Rolls-Royce Corporation (RRC) 250 model turboshaft engines. AD 2017-18-14 requires repetitive visual inspections and fluorescent penetrant inspections (FPIs) of the 3rd- stage turbine wheel and removal from service of the 4th-stage turbine wheel. Since the FAA issued AD 2017-18-14, the manufacturer redesigned the 3rd-stage turbine wheel. This proposed AD would require replacement of the 3rd-stage and 4th-stage turbine wheels. This proposed AD would also revise the applicability to add an additional turboshaft engine model. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bell Textron Canada Limited (Type Certificate Previously Held by Bell Helicopter Textron Canada Limited) Helicopters
The FAA proposes to supersede Airworthiness Directive (AD) 2020-20-06, which applies to certain Bell Helicopter Textron Canada Limited (now Bell Textron Canada Limited) Model 429 helicopters. AD 2020-20-06 requires repetitive inspections of certain cyclic and collective assembly bearings. Since the FAA issued AD 2020-20-06, the collective and cyclic bellcrank assemblies have been upgraded with corrosion resistant steel bearings. This proposed AD would retain some of the requirements of AD 2020-20-06 and depending on the inspection results, would require removing certain parts from service and installing the upgraded cyclic and collective bellcrank assemblies. This proposed AD would also require installing the upgraded collective and cyclic bellcrank assemblies on certain helicopters if not already installed, and would prohibit installing certain bellcrank assemblies. The FAA is proposing this AD to address the unsafe condition on these products.
