Airworthiness Directives; Pilatus Aircraft Ltd. Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as electrical harness installations on PC-24 airplanes that are not in compliance with the approved design. This unsafe condition could lead to wire chafing and potential arcing or failure of wires having the incorrect length, possibly resulting in loss of system redundancy, or generation of smoke and smell, or loss of power plant fire protection function. This AD requires modifying the electrical harness installation. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Piper Aircraft, Inc. Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Piper Aircraft, Inc., (Piper) Models PA-46-350P (Malibu Mirage), PA- 46R-350T (Malibu Matrix), and PA-46-500TP (Malibu Meridian) airplanes. This AD was prompted by a finding of several airplanes with wing assemblies that did not have the proper stall warning heater modification design. Without the proper stall warning heat control modification kit installed, during flights into icing conditions with the landing gear down, ice can form on the stall vane, which may result in failure of the stall warning system. This AD requires identifying and correcting nonconforming stall warning heat control systems. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Pilatus Aircraft Ltd. Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes. This AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as improperly manufactured cockpit and cabin evaporator filters installed during production on some PC-24 airplanes. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Gulfstream Aerospace Corporation Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Gulfstream Aerospace Corporation (Gulfstream) Model GVII- G600 airplanes. This proposed AD was prompted by a report that a failure mode in the data concentration network (DCN) software causes the pitch attitude value to freeze on the primary flight display (PFD) for up to 20 seconds. This proposed AD would require updating the DCN and flight deck master operating system (MOS) software. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Pilatus Aircraft Ltd. Airplanes
The FAA is adopting a new airworthiness directive (AD) for Pilatus Aircraft Ltd. (Pilatus) Model PC-12/47E airplanes. This AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as inboard flap fairings aft (IFFAs) having an incorrect shape, which may result in chafing between the IFFA and the associated front inboard tension rod. This AD requires an inspection of the IFFAs for the correct shape and chafing between the IFFA and the associated front inboard tension rod, with corrective action as necessary. This condition could lead to failure of the inboard flap drive arm with consequent asymmetric flap extension, resulting in reduced control of the airplane. The FAA is issuing this AD to address the unsafe condition on these products.
Amendment of Class D Airspace, and Class E Airspace; Smyrna, TN
This action amends Class D airspace and Class E airspace extending upward from 700 feet above the surface at Smyrna Airport, Smyrna, TN. An evaluation of airspace in the area determined that this airport required an adjustment of Class D and E airspaces. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.
Proposed Amendment of Class D and Class E Airspace, and Proposed Establishment of Class E Airspace; Worcester, MA
This action proposes to amend Class D airspace, Class E surface airspace, and Class E airspace extending upward from 700 feet above the surface for Worcester Regional Airport, Worcester, MA, as an airspace evaluation of the area determined additional airspace is necessary. Also, this action proposes to establish Class E airspace extending upward from 700 feet above the surface for UMass Memorial Medical Center-University Campus Heliport, to accommodate new area navigation (RNAV) global positioning system (GPS) standard instrument approach procedures (SIAPs) serving this heliport. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.
Proposed Establishment of Class E Airspace; Taunton, MA
This action proposes to establish Class E airspace extending upward from 700 feet above the surface for Morton Hospital Heliport, Taunton, MA, to accommodate new area navigation (RNAV) global positioning system (GPS) standard instrument approach procedures (SIAPs) serving this heliport. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area. This action would also update the name and geographic coordinates of Taunton Municipal Airport-King Field (formerly Taunton Municipal Airport), Taunton, MA.
Proposed Establishment of Class E Airspace; Crooked Creek, AK
This action proposes to establish Class E airspace extending upward from 700 feet above the surface of the earth at Crooked Creek Airport, Crooked Creek, AK.

This proposed AD was prompted by the manufacturer revising the time limits manual (TLM) to incorporate repairs to the low-pressure compressor (LPC) blades and introduce a new fan blade inspection. This proposed AD would require revisions to the airworthiness limitations section (ALS) of the Rolls-Royce (RR) Trent XWB TLM and the operator's existing approved aircraft maintenance program (AMP). The FAA is proposing this AD to address the unsafe condition on these products.
Amendment of VOR Federal Airways V-12, V-74, and V-516 in the Vicinity of Anthony, KS
This action amends VHF Omnidirectional Range (VOR) Federal airways V-12, V-74, and V-516, in the vicinity of Anthony, KS. The modifications are necessary due to the planned decommissioning of the VOR portion of the Anthony, KS, VOR/Tactical Air Navigation (VORTAC) navigation aid (NAVAID), which provides navigation guidance for portions of the affected VOR Federal airways. The Anthony VOR is being decommissioned as part of the FAA's VOR Minimum Operational Network (MON) program.
Revocation and Amendment of Class E airspace; Bucholz Army Airfield Kwajalein Atoll, Republic of the Marshall Islands
This action removes the Class E airspace designated as an extension to the Class D airspace and amends the Class E airspace extending upward from 700 and 1200 feet AGL at Bucholz AAF, Kwajalein Atoll, Republic of the Marshall Islands.
