Federal Aviation Administration February 20, 2019 – Federal Register Recent Federal Regulation Documents

We are adopting a new airworthiness directive (AD) for certain Zodiac Aerotechnics (Zodiac) oxygen mask regulators. This AD was prompted by reports that certain silicon harness inflation hoses installed on certain flight crew quick donning mask harnesses have shown an unusually high premature rupture rate. This AD requires inspection and replacement of certain oxygen mask regulator harness inflation hoses. We are issuing this AD to address the unsafe condition on these products.

This action proposes to amend Class E airspace extending upward from 700 feet above the surface at Butler County Regional Airport-Hogan Field, Hamilton, OH. The FAA is proposing this action as the result of an airspace review caused by the decommissioning of the Richmond VHF omnidirectional range (VOR) navigation aid, which provided navigation information for the instrument procedures at this airport, as part of the VOR Minimum Operational Network (MON) Program. Airspace redesign is necessary for the safety and management of instrument flight rules (IFR) operations at this airport.

This action amends Class D airspace, Class E airspace designated as an extension to a Class D surface area, and Class E airspace extending upward from 700 feet or more above the surface at Schenectady County Airport, Schenectady, NY, and Albany, NY by updating the geographic coordinates of this airport, Saratoga County Airport, Hunter NDB, and Cambridge VOR/DME. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at this airport. This action also replaces the outdated term Airport/ Facility Directory with the term Chart Supplement in the legal descriptions of associated Class D and E airspace of Schenectady County Airport, Schenectady, NY, and Ithaca Tompkins Regional Airport, Ithaca, NY. In addition, subsequent to publication, it was noted that the Cambridge VOR/DME was identified as VORTAC. This action corrects the error.

This rule amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide for the safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

This action proposes to modify Class E airspace extending upward from 700 feet above the surface at Alpine-Casparis Municipal Airport, Alpine, TX. This action is necessary due to the decommissioning of the Brewster County non-directional radio beacon (NDB), and cancellation of the NDB approach, and would enhance the safety and management of standard instrument approach procedures for instrument flight rules (IFR) operations at this airport. Additionally, the geographic coordinates are being updated to coincide with the FAA's aeronautical database.
