Department of Transportation December 10, 2018 – Federal Register Recent Federal Regulation Documents

Pursuant to a delegation of authority from the Secretary of Transportation, the Maritime Administrator is authorized to issue waivers allowing documented vessels with registry endorsements or foreign flag vessels to be used in operations that treat aquaculture fish or protect aquaculture fish from disease, parasitic infestation, or other threats to their health when suitable vessels of the United States are not available that could perform those services. A request for such a waiver has been received by the Maritime Administration (MARAD). This notice is being published to solicit comments intended to assist MARAD in determining whether suitable vessels of the United States are available that could perform the required services. If no suitable U.S.-flag vessels are available, the Maritime Administrator may issue a waiver in accordance with USCG regulations on Aquaculture at 46 CFR part 106. A brief description of the proposed aquaculture support service is listed in the Supplementary Information section below.

This editorial amendment corrects the legal description published in the Federal Register on September 11, 2018, amending Class E surface area for Louisville International Airport, Louisville, KY, by removing excessive language (E-104) from the Class E surface area legal description.

This action proposes to amend Class E airspace extending upward from 700 feet above the surface at Auburn University Regional Airport, Auburn, AL, to accommodate new area navigation (RNAV) global positioning system (GPS) standard instrument approach procedures serving this airport. Also, this action would recognize the airport's name change and update the airport's geographic coordinates. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at this airport.

This action modifies Class D airspace at Coleman A. Young Municipal Airport (formerly Detroit City Airport), Detroit, MI, by changing the airspace designation to Detroit, MI, thereby removing the old airport name. The name and geographic coordinates of this airport are also updated to coincide with the FAA's aeronautical database. This action is necessary to keep information current for the safety and management of aircraft within the national airspace system.

This action modifies Class D airspace at Oakland County International Airport, Pontiac, MI, due to the decommissioning of the Pontiac 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. This action also replaces the outdated term Airport/Facility Directory with Chart Supplement. Airspace redesign is necessary for the safety and management of instrument flight rules (IFR) operations at this airport.

We are adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-223F and Model A330-243F airplanes. This AD was prompted by a report of cracking at fastener holes located at a certain frame on the lower shell panel junction. This AD requires repetitive special detailed inspections (rototest) of certain fastener holes located at the lower shell junction of a certain frame on both left- hand (LH) and right-hand (RH) sides, and applicable related investigative and corrective actions. We are issuing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 airplanes. This AD was prompted by reports that, for multimaterial (hybrid) joints of the passenger door frame fittings, the interfay sealant was not applied between all surfaces of the joint parts. This AD requires modification of the hybrid joints of the passenger doors by applying additional corrosion protection to the hybrid joints of the passenger door frame fittings. We are issuing this AD to address the unsafe condition on these products.

We propose to supersede Airworthiness Directive (AD) 2016-16- 01, which applies to certain Airbus SAS Model A330-200 Freighter, -200, and -300 series airplanes. AD 2016-16-01 requires an inspection of affected structural parts in the cargo and cabin compartments to determine if proper heat treatment has been done, and replacement or repair if necessary. Since we issued AD 2016-16-01, we have determined that additional affected parts in the cabin compartment structure must also be inspected. This proposed AD would retain the requirements of AD 2016-16-01 and require inspection of additional locations of the cabin compartment structure. We are proposing this AD to address the unsafe condition on these products.
