Airworthiness Directives; Airbus SAS Airplanes
We are superseding Airworthiness Directive (AD) 2018-02-18, which applied to certain Airbus SAS Model A318, A319, and A320 series airplanes and Model A321-111, -112, -131, -211, -212, -213, -231, and - 232 airplanes. AD 2018-02-18 required revising the airplane flight manual (AFM) to provide guidance to the flightcrew for certain emergency procedures. This new AD requires revising the AFM, and for certain airplanes, removing a certain AFM revision. This AD also adds airplanes to the applicability. This AD was prompted by a determination that, when two angle of attack (AoA) sensors are adversely affected by icing conditions at the same time, data displayed on the back up speed scale (BUSS) could be erroneous. This AD was also prompted by a determination that the AFM needs to be revised for certain additional airplanes, and that the AFM may have been erroneously revised on certain airplanes not equipped with a BUSS function. We are issuing this AD to address the unsafe condition on these products.
Proposed Establishment of Class E Airspace; Leitchfield, KY
This action proposes to establish Class E airspace extending upward from 700 feet above the surface at Leitchfield-Grayson County Airport, Leitchfield, KY, to accommodate new area navigation (RNAV) global positioning system (GPS) standard instrument approach procedures serving the airport. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at this airport.
Amendment of Class E Airspace, Knoxville, TN; and Establishment of Class E Airspace, Madisonville, TN
This action amends Class E surface airspace at Knoxville Downtown Island Airport, Knoxville, TN, by adding to the airspace description the exclusion of a 1-mile radius around University of Tennessee Medical Center Heliport, to allow helicopters departing from the heliport to no longer require a clearance. Also, the Benfi non- directional radio beacon (NDB) has been decommissioned, requiring redesign of Class E airspace extending upward from 700 feet above the surface at McGhee-Tyson Airport, and Monroe County Airport, Madisonville, TN, is moved to stand-alone airspace with its own designation. This action is necessary to further the safety and management of Instrument Flight Rules (IFR) operations at these airports. This action also updates the geographic coordinates of Knoxville Downtown Island Airport, McGhee Tyson Airport, and Gatlinburg-Pigeon Forge Airport in the associated Class E airspace areas to coincide with the FAA's aeronautical database.
Amendment of Class D and Class E Airspace; Beaver Falls, PA; and Zelienople, PA
This action amends Class E airspace extending upward from 700 feet or more above the surface at Beaver County Airport Beaver Falls, PA, as the University of Pittsburg Medical Center Beaver Valley Heliport has closed, and controlled airspace is no longer required. The geographic coordinates of the Ellwood City VOR/DME, (incorrectly identified as VORTAC), is amended in the associated Class E airspace. Also, the term Airport Facility Directory is replaced with Chart Supplement. This action also amends Class E airspace extending upward from 700 feet or more above the surface at Zelienople Municipal Airport (formerly Zelienople Airport), PA, by recognizing the airport's name change and updating the airport's geographic coordinates. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at these airports.
