Airworthiness Directives; General Electric Company Turbofan Engines
We are adopting a new airworthiness directive (AD) for all General Electric Company (GE) GE90-110B1, GE90-113B, and GE90-115B turbofan engines with a certain case combustor assembly (combustion case) installed. This AD requires removal of affected combustion cases from service and their replacement with a part eligible for installation. This AD was prompted by the discovery of a quality escape at a manufacturing facility involving unapproved welds on combustion cases. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; General Electric Company Turbofan Engines
We are superseding Airworthiness Directive (AD) 2017-07-04 for General Electric Company (GE) GE90-110B1 and GE90-115B turbofan engines with certain high-pressure compressor (HPC) rotor stage 2-5 spools installed. AD 2017-07-04 required removing certain HPC rotor stage 2-5 spools from service at times determined by a drawdown plan. This AD requires removing certain HPC rotor stage 2-5 spools from service before reaching the new reduced life limit and replacing them with parts eligible for installation. This AD was prompted by the publication of a GE service bulletin (SB) that increases the number of affected HPC rotor stage 2-5 spools and includes HPC rotor stage 2-5 spools that were inadvertently omitted from the applicability of AD 2017-07-04. We are issuing this AD to address the unsafe condition on these products.
Agency Information Collection Activities: Requests for Comments; Clearance of a Renewed Approval of Information Collection: Procedures for Non-Federal Navigation Facilities
In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval to renew an information collection. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on August 27, 2018. The collection involves the compilation of: Commissioning data, such as the initial standards and tolerances parameters for the aerial navigation aids (NavAids) and electrical/electronic facilities, owned and operated by non-Federal sponsors; Maintenance activities and operational history, such as outages and repairs, for facilities owned and operated by non-Federal sponsors; and The facilities' periodically verified parameters for the life of the facility. The information collected is necessary to ensure that operation and maintenance of these non-Federally owned facilities is in accordance with FAA safety standards.
Receipt of Noise Compatibility Program and Request for Review for San Francisco International Airport, San Francisco, California
The Federal Aviation Administration (FAA) announces that it is reviewing a proposed noise compatibility program 2018 update that was submitted for San Francisco International Airport by the City and County of San Francisco, Airport Commission, under the provisions of the Aviation Safety and Noise Abatement Act, hereinafter referred to as ``the Act'' and the Code of Federal Regulations (CFR). This program update was submitted subsequent to a determination by FAA that associated noise exposure maps submitted for San Francisco International Airport were in compliance with applicable requirements, effective January 29, 2016. The existing noise compatibility program for San Francisco International Airport was approved by the FAA on September 7, 1983. The proposed 2018 update to the noise compatibility program will be approved or disapproved on or before April 16, 2019.
Amendment of Class E Airspace; Cambridge, MD
This action amends Class E airspace extending upward from 700 feet or more above the surface at Cambridge-Dorchester Regional Airport, Cambridge, MD, to accommodate airspace reconfiguration due to the decommissioning of the Cambridge non-directional radio beacon and cancellation of the NDB approach. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at this airport. This action also corrects the region identifier in the description header, and updates the airport name and geographic coordinates.
Establishment of Class E Airspace; Crystal Springs, MS
This action establishes Class E airspace extending upward from 700 feet above the surface at Copiah County Airport, Crystal Springs, MS, to accommodate new area navigation (RNAV) global positioning system (GPS) standard instrument approach procedures serving the airport. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at this airport.
Amendment of Class D Airspace; Tulsa, OK
This action amends Class D airspace designated as an extension at Tulsa Lloyd Jones Jr. Airport, Tulsa, OK. This action is a result of an airspace review caused by the decommissioning of the Glenpool VHF omnidirectional range (VOR) navigation aid as part of the VOR Minimum Operational Newtork (MON) Program and the cancellation of the associated instrument procedures. The geographic coordinates of the airport are also updated; to coincide with the FAA's aeronautical database, as well as an editorial change removing the city associated with the airport name in the airspace legal description. Also, the outdated term ``Airport/Facility Directory'' is replaced with ``Chart Supplement''.
Amendment of Class E Airspace, Augusta, GA, and Establishment of Class E Airspace, Waynesboro, GA
This action amends Class E airspace extending upward from 700 feet above the surface in Augusta, GA, by recognizing the name change of Augusta Regional Airport at Bush Field (formerly Augusta Regional at Bush Field Airport); removing Burke County Airport and Millen Airport from the airspace designation and establishing these two airports under Waynesboro, GA, designation; and updating the geographic coordinates of Daniel Field, Augusta, GA, and Millen Airport, Waynesboro, GA. This action accommodates airspace reconfiguration due to the decommissioning of the Millen non-directional radio beacon (NDB) and cancellation of the NDB approach at Millen Airport. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at these airports.
Prohibition Against Certain Flights in the Baghdad Flight Information Region (FIR) (ORBB)
This action reissues, with modifications to reflect changed conditions in Iraq, the Special Federal Aviation Regulation (SFAR) that prohibits certain flights in the Baghdad Flight Information Region (FIR) (ORBB) by all: U.S. air carriers; U.S. commercial operators; persons exercising the privileges of an airman certificate issued by the FAA, except when such persons are operating U.S.-registered aircraft for a foreign air carrier; and operators of U.S.-registered civil aircraft, except where the operator of such aircraft is a foreign air carrier.
Special Conditions: Innovative Solutions & Support, Inc.; Textron Aviation, Inc. Model B200-Series Airplanes; Autothrust Functions
This action proposes special conditions for Textron Aviation, Inc. B200-series airplanes. These airplanes as modified by Innovative Solutions & Support, Inc., will have a novel or unusual design feature associated with an autothrust system. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed special conditions contain the additional safety standards the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
