Federal Aviation Administration December 28, 2018 – Federal Register Recent Federal Regulation Documents

This action modifies VHF Omnidirectional Range (VOR) Federal airways V-170 and V-219 in the vicinity of Fairmont, MN. The FAA is taking this action due to the planned decommissioning of the Fairmont, MN, VOR navigation aid (NAVAID), which provides navigation guidance for portions of the affected air traffic service (ATS) routes. The Fairmont VOR is being decommissioned as part of the VOR Minimum Operational Network (MON) program.

This action proposes to modify low altitude RNAV route T-299, and establish routes T-318 and T-360 in the eastern United States. The proposal would expand the availability of RNAV routing in support of transitioning the National Airspace System (NAS) from ground-based to satellite-based navigation.

This action establishes Class E airspace extending upward from 700 feet above the surface and modifies Class E airspace designated as an extension at Olympia Regional Airport (formerly Olympia Airport). This action removes the Notice to Airmen (NOTAM) part-time status for Class E airspace designated as an extension, and updates the airport name and geographic coordinates in the associated Class D and E airspace areas to match the FAA's aeronautical database. These changes are necessary to accommodate airspace redesign for the safety and management of instrument flight rules (IFR) operations at the airport within the National Airspace System. Also, an editorial change is made to the Class D and Class E airspace legal descriptions replacing Airport/Facility Directory with the term Chart Supplement.

This action modifies Class E airspace extending upward from 1,200 feet above the surface at Atqasuk Edward Burnell Sr. Memorial Airport, Atqasuk, AK. This action adds exclusionary language to the legal description of the airport to ensure the safety and management of aircraft within the National Airspace System. Also, the geographic coordinates of the airport are updated.

We propose to adopt a new airworthiness directive (AD) for all Airbus SAS Model A330-223, A330-223F, A330-321, A330-322, and A330-323 airplanes. This proposed AD was prompted by a report of fatigue cracking in the latch beam gussets on a certain thrust reverser (T/R). This proposed AD would require a one-time special detailed inspection of certain latch beam gussets of certain T/Rs for cracks, and modifying the latch beam gussets of the T/Rs, if necessary. We are proposing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777 airplanes. This AD was prompted by reports of latently failed engine fuel shutoff spar valves discovered during fuel filter replacement. This AD requires inspecting to determine the part numbers (P/Ns) of the motor-operated valve (MOV) actuators at the engine fuel shutoff spar valve positions, installing MOV actuators having a certain acceptable part number or software if necessary, and revising the maintenance or inspection program to add a new airworthiness limitation. We are issuing this AD to address the unsafe condition on these products.

We propose to remove Airworthiness Directive (AD) 2012-02-18, which applies to all Dassault Aviation Model MYSTERE-FALCON 50 airplanes. AD 2012-02-18 requires revising the maintenance program to include revised airworthiness limitations. AD 2012-02-18 is no longer necessary because we have since issued AD 2017-09-03 to address the unsafe condition. Accordingly, we propose to remove AD 2012-02-18.

We are superseding Airworthiness Directive (AD) 2017-22-07, which applied to certain Airbus SAS Model A319 series airplanes; Model A320-211,-212, -214, -231, -232, and -233 airplanes; and Model A321- 111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2017- 22-07 required repetitive inspections of the frame forks, and corrective actions if necessary. AD 2017-22-07 also included optional modifications that constituted terminating action. This AD requires modifying certain forward and aft cargo compartment doors, and related investigative and corrective actions. This AD was prompted by an evaluation done by the design approval holder indicating that certain areas of certain cargo compartment doors are subject to widespread fatigue damage, and a determination was made that a modification of the frame forks must be done. We are issuing this AD to address the unsafe condition on these products.
