Amendment of Class E Airspace, Blue Mesa, CO
This action amends Class E en route domestic airspace extending upward from 1,200 feet above the surface near the Blue Mesa VHF Omni-Directional Radio Range/Distance Measuring Equipment (VOR/ DME), Blue Mesa, CO. The FAA has transitioned to a more accurate method of measuring, publishing, and charting airspace areas that has revealed some small areas of uncharted uncontrolled airspace. The FAA found modification of these areas of uncontrolled airspace necessary to ensure the safety of Instrument Flight Rules (IFR) operations and the efficient use of navigable airspace, including point-to-point off-airway clearances, and aircraft vectoring services.
Amendment of Class E Airspace; Cedar City, UT
This action amends the legal descriptions for Class E surface airspace and Class E airspace upward from 700 feet above the surface to correct the airport name for Cedar City Regional Airport (formerly Cedar City Municipal Airport), Cedar City, UT, and amends the airport reference point (ARP) geographic coordinates to coincide with the FAA's aeronautical database. This action also changes the name of the VHF Omnidirectional Range Distance Measuring Equipment (VOR/DME) noted in the Class E surface area airspace legal description to the Enoch VOR/ DME (formerly Cedar City VOR/DME). These changes do not affect the charted boundaries or operating requirements of the airspace.
Establishment of Class E Airspace, Healy, AK
This action establishes Class E airspace extending upward from 700 feet above the surface at Healy River Airport, Healy, AK, to support the development of Area Navigation (RNAV) Global Positioning System (GPS) Instrument Flight Rules (IFR) operations under standard instrument approach and departure procedures at the airport, and for the safety and management of controlled airspace within the National Airspace System.
National Emission Standards for Hazardous Air Pollutants: Nutritional Yeast Manufacturing Risk and Technology Review
The Environmental Protection Agency (EPA) is proposing amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Manufacturing of Nutritional Yeast source category. The proposed amendments address the results of the residual risk and technology reviews (RTRs) conducted as required under the Clean Air Act (CAA) as well as other actions deemed appropriate during the review of these standards. The proposed amendments include revising the form of the fermenter volatile organic compounds (VOC) emission limits, changing the testing and monitoring requirements, and updating the reporting and recordkeeping requirements.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A330-200, A330-200 Freighter, A330-300, A340-500, and A340-600 series airplanes; and A340-313 airplanes. This proposed AD was prompted by the discovery of Tartaric Sulfuric Anodizing (TSA)/Chromic Acid Anodizing (CAA) surface treatment in certain bulk cargo door frame holes of certain airplanes. This proposed AD would require inspection of the fuselage bulk cargo door frames at specific locations, and corrective action if necessary. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
We propose to supersede Airworthiness Directive (AD) 2013-19- 09 and AD 2014-25-51, for all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2013-19-09 currently requires replacing Angle of Attack (AOA) sensor conic plates with AOA sensor flat plates. AD 2014- 25-51 currently requires revising the airplane flight manual (AFM) to advise the flightcrew of emergency procedures for abnormal Alpha Protection (Alpha Prot). Since we issued AD 2013-19-09 and AD 2014-25- 51, we have received a report indicating that certain AOA sensors appear to have a greater susceptibility to adverse environmental conditions. This proposed AD would require replacing certain AOA sensors; and doing a detailed inspection and a functional heating test for discrepancies on certain AOA sensors, and replacing the affected AOA sensors. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 and 787-9 airplanes. This proposed AD was prompted by wire harness chafing on the electro-mechanical actuators (EMAs) for certain spoilers due to insufficient separation with adjacent structure. This proposed AD would require replacement of affected EMAs. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; M7 Aerospace LLC Airplanes
We propose to adopt a new airworthiness directive (AD) for certain M7 Aerospace LLC Models SA226-T, SA226-AT, SA226-T(B), SA226- TC, SA227-AC (C-26A), SA227-AT, SA227-BC (C-26A), SA227-CC, SA227-DC (C-26B), and SA227-TT airplanes. This proposed AD was prompted by detachment of the power lever linkage to the TPE331 engine propeller pitch control. This proposed AD would require installing a secondary retention device and repetitively inspecting the propeller pitch control for proper torque, with corrections as necessary. We are proposing this AD to correct the unsafe condition on these products.
Airworthiness Directives; Sikorsky Aircraft Corporation
We are publishing a new airworthiness directive (AD) for Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters, which was sent previously to all known U.S. owners and operators of these helicopters. This AD requires inspecting certain bearings. This AD is prompted by a report of a failed bearing. We are issuing this AD to address the unsafe condition on these products.
Energy Conservation Program: Test Procedure for Walk-in Coolers and Walk-in Freezers
This final rule amends the test procedure for certain walk-in cooler and freezer components by improving the procedure's clarity, updating related certification and enforcement provisions to address the performance-based energy conservation standards for walk-in cooler and freezer equipment, and establishing labeling requirements to aid manufacturers in determining compliance with the relevant standards for walk-in cooler and freezer applications. The amendments consist of provisions specific to certain walk-in cooler and freezer refrigeration systems, including product-specific definitions, removal of a performance credit for hot gas defrost, and a method to accommodate refrigeration equipment that use adaptive defrost and on-cycle variable-speed evaporator fan control.
