Department of Transportation August 21, 2017 – Federal Register Recent Federal Regulation Documents

The Secretary of Transportation, as represented by the Maritime Administration (MARAD), is authorized to grant waivers of the U.S.-build requirement of the coastwise laws under certain circumstances. A request for such a waiver has been received by MARAD. The vessel, and a brief description of the proposed service, is listed below.

This action proposes to establish Class E airspace at Rosebud, SD. Controlled airspace is necessary to accommodate new special instrument approach procedures developed at Rosebud Sioux Tribal Airport, for the safety and management of instrument flight rules (IFR) operations at the airport.

In a March 22, 2017, Federal Register document, the Environmental Protection Agency (EPA) announced its intention to reconsider the Final Determination of the Mid-term Evaluation of greenhouse gas emissions standards for model year 2022-2025 light-duty vehicles and to coordinate its reconsideration with the parallel rulemaking process to be undertaken by the Department of Transportation's National Highway Traffic Safety Administration (NHTSA) regarding Corporate Average Fuel Economy (CAFE) standards for cars and light trucks for the same model years. In this document, EPA is announcing that it is reconsidering whether the light-duty vehicle greenhouse gas standards previously established for model years 2022- 2025 are appropriate under section 202(a) of the Clean Air Act and invites stakeholders to submit any comments, data, and information they believe are relevant to the Administrator's reconsideration of the January 2017 Mid-term Evaluation Final Determination and in particular, highlight any new information. As part of a 2012 joint final rulemaking by the EPA and NHTSA, the Mid-term Evaluation process was codified in EPA regulation for greenhouse gas emission standards for model years 2017-2025 light-duty vehicles, which requires EPA to determine no later than April 1, 2018, whether the standards for model years 2022-2025 are appropriate.\1\ In accord with this schedule, as noted in the March 22, 2017, document and this document, EPA intends to make a Final Determination regarding the appropriateness of the model year 2022-2025 standards no later than April 1, 2018. In this document, EPA is also requesting comment on the separate question of whether the light-duty vehicle greenhouse gas standards established for model year 2021 remain appropriate, regardless of the agency's decision on the MTE.

We are adopting a new airworthiness directive (AD) for certain Airbus Model A300 series airplanes; and Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). This AD was prompted by reports of cracks initiating at the upper radius of a certain frame and a determination that the current inspection procedure is not reliable in detecting certain cracking of the forward fitting of the frame. This AD requires repetitive inspections to detect cracking of the upper radius of the forward fitting of a certain frame, and related investigative actions and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.

We are superseding Airworthiness Directive (AD) 2014-20-09, which applied to certain Bombardier, Inc., Model DHC-8-400 series airplanes. AD 2014-20-09 required an inspection for missing clamps that are required to provide positive separation between the alternating current (AC) feeder cables and the hydraulic line of the landing gear alternate extension, and related investigative and corrective actions if necessary. This new AD requires removing airplanes from the AD applicability. This AD was prompted by reports of missing clamps that are required to provide positive separation between the AC feeder cables and the hydraulic line of the landing gear alternate extension. We are issuing this AD to address the unsafe condition on these products.

We are superseding Airworthiness Directive (AD) 2014-16-01 for MD Helicopters, Inc. (MDHI), Model MD900 helicopters. AD 2014-16-01 required an eddy current inspection of the main rotor upper hub assembly (upper hub) for a crack. This AD requires additional inspections and replacing the fillet seal. This AD was prompted by three additional reports of upper hub cracks. The actions of this AD are intended to prevent an unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 777 airplanes. This AD was prompted by reports of cracks on the underwing longerons. This AD requires repetitive inspections of the left and right side underwing longerons for any crack, and related investigative and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.

We are revising an earlier proposal for certain The Boeing Company Model 777 airplanes. This action revises the notice of proposed rulemaking (NPRM) by adding an inspection to determine a part number and to incorporate an airworthiness limitation (AWL) into the maintenance or inspection program. This action also revises the NPRM by specifying a new version of the airline information management system (AIMS) software for airplanes equipped with AIMS-2 software. We are proposing this Airworthiness Directive (AD) to address the unsafe condition on these products. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
