Proposed Modification and Establishment of Area Navigation (RNAV) Routes; Western United States
This action proposes to modify three RNAV Q-routes and establish five Q-routes originating in Oakland Air Route Traffic Control Center's (ARTCC) airspace. The routes would promote operational efficiencies for users and provide connectivity to current and proposed RNAV en route and terminal procedures.
Approval of Noise Compatibility Program for Willow Run Airport, Ypsilanti, Michigan
The FAA announces its findings on the noise compatibility program submitted by the City of Ypsilanti, Michigan under the provisions of 49 U.S.C. 47501 et seq. (formerly the Aviation Safety and Noise Abatement Act, hereinafter referred to as ``the Act'') and 14 CFR Part 150 (hereinafter referred to as ``Part 150''). On January 15, 2014, the FAA determined that the noise exposure maps submitted by the City of Ypsilanti, Michigan under Part 150 were in compliance with applicable requirements. On May 20, 2014 the FAA approved the Willow Run Airport noise compatibility program. This is the first Record of Approval (ROA) for the YIP NCP, which included nine measures recommended for approval. No program elements relating to new or revised flight procedures for noise abatement were proposed by the airport operator.
Membership in the National Parks Overflights Advisory Group Aviation Rulemaking Committee
By Federal Register notice (See 79 FR 18757, April 3, 2014) the National Park Service (NPS) and the Federal Aviation Administration (FAA) invited interested persons to apply to fill two openings on the National Parks Overflights Advisory Group (NPOAG) Aviation Rulemaking Committee (ARC). The notice invited interested persons to apply to fill one upcoming and one currently vacant seat, both representing environmental concerns. This notice informs the public of the person selected to fill one of the vacancies, no selection has been made for the other open vacancy representing environmental concerns.
Establishment of Class E Airspace; Conway, AR
This action establishes Class E airspace at Conway, AR. Controlled airspace is necessary to accommodate new Area Navigation (RNAV) Standard Instrument Approach Procedures at Cantrell Field. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at the airport.
Establishment of Class E Airspace; Mineral Point, WI
This action establishes Class E airspace at Mineral Point, WI. A Class E surface area is necessary to accommodate increased business aviation and flight instruction activity at Iowa County Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations for SIAPs at the airport. Geographic coordinates of the existing Class E airspace are also updated.
Airworthiness Directives; Airbus Helicopters (Previously Eurocopter France) (Airbus Helicopters) Helicopters
We propose to supersede airworthiness directive (AD) 2013-21- 01 that currently applies to Eurocopter France Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, AS350D, AS350D1, AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters. AD 2013-21-01 currently requires certain inspections of each tail rotor pitch horn assembly (pitch horn) for a crack and, if there is a crack, before further flight, replacing the pitch horn with an airworthy pitch horn. AD 2013-21-01 also requires a one-time visual inspection for pitch horns above certain hours time-in-service (TIS). This NPRM would retain the requirements of AD 2013-21-01 but would require a repetitive visual inspection for all pitch horns regardless of hours TIS, which requires allowing the public an opportunity to comment. These proposed actions are intended to detect a crack in the pitch horn to prevent failure of the pitch horn, loss of the anti-torque function, and subsequent loss of control of the helicopter.
Airworthiness Directives; Bell Helicopter Textron, Inc. (Bell) Helicopters
We are superseding Airworthiness Directive (AD) 2013-11-05 for Bell Model 214B, 214B-1, and 214ST helicopters with certain tail rotor hanger bearings (bearing) installed. AD 2013-11-05 required inspecting the bearing to determine whether an incorrectly manufactured seal material is installed on the bearing. This new AD retains the repetitive inspection of the bearings and also requires replacing the defective bearings. This AD was prompted by a report that certain bearings were manufactured with an incorrect seal material that does not meet Bell specifications. We are issuing this AD to prevent failure of the bearing and subsequent loss of control of the helicopter.
