Federal Aviation Administration March 2021 – Federal Register Recent Federal Regulation Documents

This rule establishes, amends, suspends, or removes Standard Instrument Approach Procedures (SIAPS) and associated Takeoff Minimums and Obstacle Departure procedures (ODPs) for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

The FAA is adopting a new airworthiness directive (AD) for certain Safran Helicopter Engines, S.A. (Safran Helicopter Engines) Arriel 1B, Arriel 1C, Arriel 1C2, Arriel 1D1, Astazou XIV B, and Astazou XIV H model turboshaft engines. This AD was prompted by the detection of positive segregation (freckles) on Stage 2 high-pressure turbine (HPT) disks and Stage 3 turbine wheels. This AD requires removal from service of certain Stage 2 HPT disks for Safran Helicopter Engines Arriel 1B, 1C, 1C2, and 1D1 model turbofan engines and affected Stage 3 turbine wheels for Safran Helicopter Engines Astazou XIV B and XIV H model turbofan engines. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2018-24- 03, which applied to all Dassault Aviation Model Falcon 10 airplanes. AD 2018-24-03 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance requirements and airworthiness limitations. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations; 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.

This action proposes to amend VOR Federal airway V-487 in the vicinity of Glens Falls, NY, and Burlington, VT. The proposed change would substitute a radial from the Burlington, VT, VOR/DME (BTV), in place of the current Glens Falls, NY, VOR/DME (GFL) radial, for defining a navigation fix along the route. Additionally, this action would remove segments of V-487 between Burlington, VT, and St Jean, Canada. These changes are necessary due to the decommissioning of the Glens Falls, NY, VOR/DME, and the decommissioning of the St Jean, Canada VOR/DME (YJN).

The FAA proposes to supersede Airworthiness Directive (AD) 2016-08-20 for certain Airbus Helicopters (previously Eurocopter France) EC130B4 and EC130T2 helicopters. AD 2016-08-20 requires repetitively inspecting the tail boom to Fenestron junction frame (junction frame) for a crack. Since the FAA issued AD 2016-08-20, additional cracks have been reported and a design change that modifies the junction frame has become available. This proposed AD would continue to require inspecting the junction frame with the horizontal stabilizer removed, and would propose to expand the applicability, revise the compliance time and the inspection procedures for inspecting the junction frame, add inspection procedures for certain helicopters, allow repair of the junction frame, and would require modifying and then repetitively inspecting the junction frame and reporting certain information. The actions of this proposed AD are intended to address an unsafe condition on these products.

This notice announces a meeting of the NextGen Advisory Committee (NAC).

This action proposes to amend restricted area R-7001C and establish three restricted areas, R-7001D, R-7002A, R-7002B, and R- 7002C at Guernsey, WY. The Wyoming Army National Guard (WYARNG) requested the establishment of the new restricted areas to support its air-to-ground firing from helicopters and longer range artillery training. This additional airspace allows for the segregation of hazardous activities from non-participating air traffic. The FAA is also proposing to amend R-7001C to correct an inadvertent error to ensure proper vertical separation.

The FAA proposes to adopt a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (AHD) Model MBB-BK 117 D-2 helicopters. This proposed AD was prompted by a report of a broken Titanium (Ti) bolt. This proposed AD would require removing certain Ti- bolts from service and prohibit installing these Ti-bolts in a critical area. The FAA is proposing this AD to address the unsafe condition on these products.

This action proposes to establish area navigation (RNAV) routes T-322, T-392, T-403, and T-405 in the central United States. The proposed new RNAV routes would expand the availability of RNAV routing in support of transitioning the National Airspace System (NAS) from ground-based to satellite-based navigation. Additionally, a portion of the new RNAV routes would provide enroute structure where VHF Omnidirectional Range (VOR) Federal airway segments were removed due to the Sioux City, IA; Park Rapids, MN; and Huron, SD, VORs decommissioning in support of the FAA's VOR Minimum Operational Network (MON) program.

This notice contains a summary of a petition seeking relief from specified requirements of Federal Aviation Regulations. The purpose of this notice is to improve the public's awareness of, and participation in, the FAA's exemption process. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of the petition or its final disposition.

This action modifies the Class E airspace, designated as an extension to a Class D or Class E surface area, at Palmdale USAF Plant 42 Airport. This action also modifies the Class E airspace, extending upward from 700 feet above the surface. Additionally, this action removes the Class E airspace, extending upward from 1,200 feet above the surface. Further, this action removes the Palmdale VORTAC from the Class E4 and the Class E5 legal descriptions. Also, this action removes the Lancaster, Gen. William J. Fox Airfield, CA, from the Class E5 legal description. Lastly, this action implements several administrative corrections to the Class D, Class E4, and Class E5 text headers and legal descriptions.
