Federal Aviation Administration June 22, 2018 – Federal Register Recent Federal Regulation Documents

This action modifies VHF Omnidirectional Range (VOR) Federal airways V-2, V-26, V-84, V-218, and V-510 in the vicinity of Lansing, MI, and removes airway V-410 in the vicinity of Pontiac, MI. These modifications are required due to the planned decommissioning of the Lansing, MI, VHF Omnidirectional Range/Tactical Air Navigation (VORTAC) and the Pontiac, MI, VORTAC navigation aids, which provide navigation guidance for portions of the above routes.

This action amends Class E airspace at Duplin County Airport, Kenansville, NC, to accommodate airspace reconfiguration due to the decommissioning of the Kenan non-directional radio beacon (NDB), and cancellation of the NDB approach. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at this airport. This action also updates the geographic coordinates of this airport.

This action proposes to amend Class E airspace extending upward from 700 feet or more above the surface at Bloomsburg, PA, due to the decommissioning of the Milton very high frequency omni- directional range collocated tactical air navigation aid (VORTAC) which requires airspace reconfiguration at Bloomsburg Municipal Airport. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at the airport. This action also would update the geographic coordinates of the airport.

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model DHC-8-400 series airplanes. This proposed AD was prompted by a report of broken P-clamps on the pressure relief line and the motive flow line in the left and right fuel tanks, and fouling conditions between the motive flow line and the collector tank partition wall in both fuel tanks. This proposed AD would require, depending on airplane configuration: Increasing the hole size in the collector tank partition wall, inspecting the motive flow line for damage, and replacing the associated grommet and motive flow line; replacing the affected single nut plate brackets and standoffs at the affected stations on the motive flow line and pressure relief line; and inspecting the motive flow line and vent line at certain wing stations, and inspecting the fuel tubes, to verify that an appropriate clearance has been maintained between the fuel tubes and their support brackets, and applicable corrective actions. We are proposing this AD to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for all Dassault Aviation Model MYSTERE-FALCON 200 airplanes. This proposed AD was prompted by a determination that more restrictive maintenance requirements and airworthiness limitations are necessary. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance requirements and airworthiness limitations. We are proposing this AD to address the unsafe condition on these products.
