Airworthiness Directives; General Electric Company Turbofan Engines
We propose to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) GEnx-2B67, -2B67B, and -2B67/P turbofan engines. This proposed AD was prompted by low-cycle fatigue (LCF) cracking of the fuel manifold leading to an engine fire. This proposed AD would require removal from service of certain fuel manifolds at the next engine shop visit and their replacement with parts eligible for installation. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
We propose to supersede Airworthiness Directive (AD) 2017-22- 07, which applies to certain Airbus Model A319 series airplanes; Model A320-211, -212, -214, -231, -232, and -233 airplanes; and Model A321- 111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2017- 22-07 requires repetitive inspections of the frame forks, and corrective actions if necessary. AD 2017-22-07 also includes optional modifications that constitute terminating action. Since we issued AD 2017-22-07, an evaluation was done by the design approval holder (DAH) indicating that the frame forks and outer skin on the forward and aft cargo compartment doors are subject to widespread fatigue damage (WFD), and a determination was made that a modification of the frame forks must be accomplished. This proposed AD would require modifying certain forward and aft cargo compartment doors, and related investigative and corrective actions. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Leonardo S.p.A. Helicopters (Type Certificate Previously Held By Finmeccanica S.p.A., AgustaWestland S.p.A)
We are adopting a new airworthiness directive (AD) for Leonardo S.p.A. (Leonardo) Model A109E, A109S, and AW109SP helicopters with an oil cooler fan assembly (fan assembly) installed. This AD requires inspecting each oil cooler system pulley assembly (pulley assembly) bearing and replacing each fan assembly. This AD is prompted by reports of degraded pulley assembly bearings. The actions of this AD are intended to correct an unsafe condition on these products.
Schedule of Application Fees
In this document, the Federal Communications Commission (Commission) revises the FY 2018 application fee rates based on increases in the Consumer Price Index.
Air Plan Approval and Air Quality Designation; MO; Redesignation of the Missouri Portion of the St. Louis Missouri-Illinois Area to Attainment of the 1997 Annual Standards for Fine Particulate Matter and Approval of Associated Maintenance Plan
On January 5, 2018, the Environmental Protection Agency (EPA) published in the Federal Register an advanced notice of proposed rulemaking (ANPR) specifically requesting early input and comments on the Agency's interpretation that air quality monitoring data from 2015- 2017 support a finding that the Missouri Portion of the St. Louis nonattainment area attains the 1997 Annual National Ambient Air Quality Standards (NAAQS) for fine particulate matter (PM2.5). The notice also provided an evaluation of Missouri's 1997 Annual PM2.5 NAAQS maintenance plan, which includes the 2008 and 2025 NOX and PM2.5 motor vehicle emission budgets (MVEBs) and established the 2008 base year emissions inventory. EPA received no comments on the ANPR. EPA is now taking direct final action on three items, consistent with the ANPR. First, EPA is approving the state's request to redesignate the Missouri portion of the St. Louis MO-IL nonattainment area to attainment for the 1997 Annual PM2.5 NAAQS as the monitoring values demonstrate the area attains the standard. Second, EPA is approving the state implementation plan (SIP) revision containing a maintenance plan for the Missouri portion of the area including the motor vehicle emissions budget. Third, EPA is approving Missouri's 2008 base year emissions inventory in accordance with section 172(c)(3) of the CAA. In the ``Rules and Regulations'' section of this Federal Register, we are approving the state's SIP revisions as a direct final rule without a prior proposed rule. If we receive no adverse comment, we will not take further action on this proposed rule.
