This action modifies Class E airspace extending upward from 700 feet above the surface at Midland International Air and Space Port Airport (formerly Midland International Airport), Midland, TX, due to the closing of Mabee Ranch Airport, decommissioning of the Mabee non- directional radio beacon (NDB), and cancellation of NDB approaches at Mabee Ranch Airport. Additionally, this action establishes Class E airspace extending upward from 700 feet above the surface at Odessa Airport-Schlemeyer Field, Odessa, TX and Midland Airpark, Midland, TX, to accommodate special instrument approach procedures developed at these airports to enhance the safety and management of standard instrument approach procedures for instrument flight rules (IFR) operations. Also, an editorial change is made to the Class E surface area airspace legal description replacing Airport/Facility Directory with the term Chart Supplement. In addition, the airport name is changed to Midland International Air and Space Port Airport to coincide with the FAA's aeronautical database.

This action proposes to amend Class D airspace and establish Class E airspace designated as a surface area at University of Oklahoma Westheimer Airport, Norman, OK. The University of Oklahoma Westheimer Airport requested establishment of this airspace. This action would also amend Class E airspace extending upward from 700 feet above the surface at the University of Oklahoma Westheimer Airport, Norman, OK, contained within the Oklahoma City, OK, airspace description, by removing the Oklahoma Westheimer Airport ILS localizer and realigning the southwest segment. Additionally, the name of the University of Oklahoma Westheimer Airport would be updated to coincide with the FAA's aeronautical database in Class D airspace. This action is necessary for the safety and management of instrument flight rules (IFR) operations at the airport.

We are revising an earlier notice of proposed rulemaking (NPRM) for all Airbus Model A318-111 and -112 airplanes; Model A319- 111, -112, -113, -114, and -115 airplanes; Model A320-211, -212, and - 214 airplanes; and Model A321-111, -112, -211, -212, and -213 airplanes. This action revises the NPRM by expanding the list of affected engine fan cowl door (FCD) part numbers and adding Airbus Model A320-216 airplanes to the applicability. We are proposing this Airworthiness Directive (AD) to address the unsafe condition on these products. Since these actions impose an additional burden over those proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.

NHTSA is issuing this final rule to amend Federal Motor Vehicle Safety Standard (FMVSS) No. 305, ``Electric-powered vehicles: Electrolyte spillage and electrical shock protection,'' to adopt various electrical safety requirements found in Global Technical Regulation (GTR) No. 13, ``Hydrogen and fuel cell vehicles,'' and other sources. This final rule updates FMVSS No. 305 using modern and harmonized safety requirements and facilitates the introduction of new technologies, including hydrogen fuel cell vehicles (HFCVs) and 48-volt mild hybrid technologies. This final rule is a deregulatory action. It imposes no costs and adjusts FMVSS No. 305 to give more flexibility to manufacturers not only to use modern electrical safety designs to produce electric vehicles, but also to introduce new technologies to the U.S. market. To expand FMVSS No. 305's performance requirements beyond post-crash conditions, NHTSA adopts electrical safety requirements to protect against direct and indirect contact of high voltage sources during everyday operation of electric-powered vehicles. Also, NHTSA adopts an optional method of meeting post-crash electrical safety requirements, consistent with that in GTR No. 13, involving use of physical barriers to prevent direct or indirect contact (by occupants, emergency services personnel and others) with high voltage sources.

We are superseding Airworthiness Directive (AD) 2014-26-10, which applied to all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2014-26-10 required revising the maintenance or inspection program to incorporate maintenance requirements and airworthiness limitations. This new AD requires revising the maintenance or inspection program, as applicable, to incorporate new or revised airworthiness limitation requirements. This AD was prompted by a determination that more restrictive maintenance instructions and airworthiness limitations are necessary. We are issuing this AD to address the unsafe condition on these products.
