Federal Aviation Administration February 28, 2019 – Federal Register Recent Federal Regulation Documents

The FAA is withdrawing a notice of proposed rulemaking (NPRM) that proposed to adopt a new airworthiness directive (AD) that would have applied to certain Mitsubishi Heavy Industries, Ltd. Models MU-2B- 10, MU-2B-15, MU-2B-20, MU-2B-25, MU-2B-26, MU-2B-26A, MU-2B-30, MU-2B- 35, MU-2B-36, MU-2B-36A, MU-2B-40, and MU-2B-60 airplanes. The NPRM resulted 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 and would have required repetitively inspecting the wing spacer plates for cracks until they were replaced with an improved design wing spacer plates. Since issuance of the NPRM, we determined that damage is contained to the wing spacer plate with no evidence that primary structure is affected. Accordingly, the NPRM is withdrawn.

This action proposes to modify Class E airspace extending upward from 700 feet above the surface at Brady, Curtis Field, Brady, TX. This action is necessary due to the decommissioning of the Brady non-directional radio beacon (NDB), and cancellation of the NDB approach. It 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.

This action proposes to amend the Class E surface area and Class E airspace extending upward from 700 feet above the surface at Mount Vernon Airport, Mount Vernon, IL. The FAA is proposing this action as the result of an airspace review caused by the decommissioning of the Mount Vernon 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. The geographic coordinates and name of the airport would also be updated to coincide with the FAA's aeronautical database. Airspace redesign is necessary for the safety and management of instrument flight rules (IFR) operations at this airport.
