Proposed Amendment of VOR Federal Airways V-35 and V-267; Eastern United States
This action proposes to modify VHF omnidirectional range (VOR) Federal airways V-35 and V-276 due to the scheduled decommissioning of the Tyrone, PA, VORTAC facility, which provides navigation guidance for portions of the routes. Once the VORTAC is decommissioned, the FAA plans a waypoint to be established for point-to-point area navigation for continued safety and management within the National Airspace System.
Proposed Modification of Air Traffic Service (ATS) Routes; North Central United States
This action proposes to modify three Jet Routes (J-45, J-151, and J-233) and a high altitude area navigation (RNAV) route (Q-19). The FAA is proposing this action due to a service restriction of the Des Moines, IA (DSM), VHF Omnidirectional Range (VOR)/Tactical Air Navigation (VORTAC) facility that provides navigation guidance for a portion of the ATS routes. This action would enhance the safety and efficient management of aircraft flying within the National Airspace System (NAS).

Aviation Rulemaking Advisory Committee Engine Endurance Testing Requirements-New Task
The FAA assigned ARAC a new task to review existing engine endurance test requirements, assess its suitability for all engines, and consider an alternate endurance test and associated methods of compliance. The current regulations may not adequately address the technological advances found in modern engines, as related to the current engine endurance test. This notice informs the public of the new ARAC activity and solicits membership for the Engine Harmonization Working Group (EHWG).
Airworthiness Directives; Turbomeca S.A. Turboshaft Engines
We are adopting a new airworthiness directive (AD) for all Turbomeca S.A. Arrius 2F turboshaft engines. This AD requires a one- time inspection of the ejector assembly nozzle of an affected lubricating device and, if a discrepancy is found, removal and replacement with a part eligible for installation. This AD was prompted by an in-flight shutdown (IFSD) of an Arriel 1 engine. We are issuing this AD to prevent failure of the ejector assembly nozzle, which could lead to an IFSD of the engine, damage to the engine, and damage to the helicopter.
