May 15, 2018 – Federal Register Recent Federal Regulation Documents

We are adopting a new airworthiness directive (AD) for certain Airbus Model A318 series airplanes and Model A319 series airplanes; all Model A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and all Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. This AD was prompted by an evaluation by the design approval holder (DAH) indicating that the holes of the upper cleat to upper stringer attachments at certain areas of the left- and right-hand wings are subject to widespread fatigue damage (WFD). This AD requires modifying the holes of the upper cleat to upper stringer attachments at certain areas of the left- and right-hand wings. We are issuing this AD to address the unsafe condition on these products.

EPA issued a notice in the Federal Register of March 21, 2018, concerning a Notice of filingNew Tolerance Exemptions for Inerts (except PIPs). This document corrects a typographical error.

The Environmental Protection Agency (EPA) is proposing to approve a state implementation plan (SIP) revision submitted by the State of Delaware. This revision pertains to the infrastructure requirement for interstate transport of pollution with respect to the 2012 fine particulate matter (PM2.5) national ambient air quality standards (NAAQS). EPA is proposing approval of this revision in accordance with the requirements of the Clean Air Act (CAA).

NMFS is opening directed fishing for species that comprise the deep-water species fishery by vessels using trawl gear in the Gulf of Alaska (GOA). This action is necessary to fully use the 2018 groundfish total allowable catch specified for the species comprising the deep- water species category in the GOA.

This document provides notification of substantive rules issued by the Coast Guard that were made temporarily effective but expired before they could be published in the Federal Register. This document lists temporary safety zones, security zones, special local regulations, drawbridge operation regulations and regulated navigation areas, all of limited duration and for which timely publication in the Federal Register was not possible.

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A319-115 and -132 airplanes, and Model A320-214, - 216, -232, and -233 airplanes. This proposed AD was prompted by a report indicating that certain modified airplanes do not have electrical ground wires on the fuel level sensing control unit (FLSCU), which adversely affects the fuel gravity feeding operation. This proposed AD would require modification of the FLSCU wiring. We are proposing this AD to address the unsafe condition on these products.

The Coast Guard has issued a temporary deviation from the operating schedule that governs the Sacramento County highway bridge across Georgiana Slough, mile 12.4, near Walnut Grove, CA. The deviation is necessary to allow participants in the AMGEN Tour of California bicycle race to cross the drawspan safely and without interruption. This deviation allows the bridge to remain in the closed- to-navigation position during the deviation period.

NMFS issues this final rule for the 2018 Pacific whiting fishery under the authority of the Pacific Coast Groundfish Fishery Management Plan (FMP), the Magnuson-Stevens Fishery Conservation and Management Act (Magnuson-Stevens Act), and the Pacific Whiting Act of 2006. This final rule announces the 2018 U.S. Total Allowable Catch of 441,433 metric tons (mt) of Pacific whiting, establishes a tribal allocation of 77,251 mt, establishes a set-aside for research and bycatch of 1,500 mt, and announces the allocations of Pacific whiting to the non-tribal fishery for 2018. The catch limits in this rule are intended to ensure the long-term sustainability of the Pacific whiting stock.

We propose to supersede Airworthiness Directive (AD) 2017-16- 05, which applies to certain The Boeing Company Model 737-600, -700, - 700C, -800, -900, and -900ER series airplanes. AD 2017-16-05 requires a one-time detailed visual inspection for discrepancies in the Krueger flap bullnose attachment hardware, and related investigative and corrective actions if necessary. Since we issued AD 2017-16-05, we received a report of a missing no. 2 Krueger flap bullnose hinge bolt from an airplane that was not included in the applicability of AD 2017- 16-05. This proposed AD would add airplanes and an additional inspection to determine if any Krueger flap no. 1, 2, 3, or 4 has been replaced, and related investigative and corrective actions. Since this is a rotable parts issue, the applicability of this AD has been expanded beyond the airplanes listed in the related service bulletin to include all airplanes on which a Krueger flap bullnose may be installed. We are proposing this AD to address the unsafe condition on these products.

We propose to supersede Airworthiness Directive (AD) 2016-13- 16, which applies to all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. AD 2016-13-16 requires an inspection or records check to determine if affected horizontal stabilizers are installed, related investigative actions, and, for affected horizontal stabilizers, repetitive inspections for any crack of the horizontal stabilizer rear spar upper chord, and corrective action if necessary. Since we issued AD 2016-13-16, we have determined that clarification of inspection areas and serial number information of the horizontal stabilizer is necessary. Therefore, this proposed AD would retain the requirements of AD 2016-13-16, with revised service information that clarifies the inspection areas and serial number information of the horizontal stabilizer. We are proposing this AD to address the unsafe condition on these products.

This final rule amends the Pension Benefit Guaranty Corporation's regulation on Benefits Payable in Terminated Single- Employer Plans to prescribe interest assumptions under the regulation for valuation dates in June 2018. The interest assumptions are used for paying benefits under terminating single-employer plans covered by the pension insurance system administered by PBGC.

We are adopting a new airworthiness directive (AD) for certain Pacific Aerospace Limited Model 750XL airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as abrasion damage to the wing leading edge that could result in a fuel leak. We are issuing this AD to require actions to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD was prompted by reports indicating additional cracking in the inspar upper skin at wing buttock line (WBL) 157 and in the skin at two holes common to the rear spar in the same area, and rear spar web cracks were also noted on both wings. Subsequent inspections revealed that the right rear spar upper chord was almost completely severed and the left rear spar upper chord was completely severed. Additional reports identified cracking in the main landing gear (MLG) beam forward support fitting. This AD requires the installation of standard-size fasteners for a certain configuration and inspections for any crack in certain locations of the rear spar. We are issuing this AD to address the unsafe condition on these products.
