Federal Aviation Administration September 2017 – Federal Register Recent Federal Regulation Documents

In preparation for the International Civil Aviation Organization's (ICAO) Dangerous Goods Panel (DGP) meeting to be held October 16-October 27, 2017, in Montreal, Canada, the Federal Aviation Administration's (FAA) Office of Hazardous Materials Safety and the Pipeline and Hazardous Materials Safety Administration's (PHMSA) Office of Hazardous Materials Safety announce a public meeting.

The FAA is issuing this notice to advise the public of the renewal of the RTCA Charter (FAA Order 1110.77X) for 6 months, effective September 29, 2017. The Federal Aviation Administration (FAA) is authorized to establish the RTCA advisory committee in accordance with the provisions of the Federal Advisory Committee Act (FACA). The current charter agreement requires that the RTCA manage various Federal subcommittees on behalf of the agency. The objective of the advisory committee is to seek resolution of issues and challenges involving air transportation concepts, requirements, operational capabilities, the associated use of technology, and related considerations to aeronautical operations that affect the future of the Air Traffic Management System and the integration of new technologies.

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 757-300 series airplanes. This proposed AD was prompted by reports of scribe line damage on fuselage skin. This proposed AD would require detailed inspections of fuselage skin for the presence of scribe lines, and applicable on-condition actions. We are proposing this AD to address the unsafe condition on these products.

The Federal Aviation Administration (FAA) announces that it has discontinued preparation of an Environmental Impact Statement (EIS) for a construction of a Replacement General Aviation Airport for Mesquite, Nevada. On November 14, 2011, FAA published a notice of suspension of the EIS in the Federal Register (76 FR 70530). The FAA received a letter dated September 27, 2011, from the City of Mesquite, Nevada asking the FAA to suspend any further work on the EIS. The reasons for this action include the local economic conditions in Mesquite and other local fiscal and budgetary constraints. The Mesquite Lands Act of 1988 (the Act), as amended, provided land to the City of Mesquite for the replacement airport, expired on November 14, 2011 and was not extended or renewed by Congress. The original purpose and need for the proposed relocated airport no longer exists. The City of Mesquite, the owner and operator of the existing Mesquite Municipal Airport, has not included a replacement airport in its 5-year Airport Capital Improvement Program. As a result, FAA has determined the proposed replacement General Aviation Airport for Mesquite, Nevada is not ripe for decision at this time.

The FAA is issuing this notice to advise the public of a meeting of Eighty Sixth RTCA SC-147 Plenary Session. This is a subcommittee to RTCA.

The FAA is issuing this notice to advise the public of a meeting of Forty Ninth RTCA SC-206 Plenary. This is a subcommittee to RTCA.

We are adopting a new airworthiness directive (AD) for all Honeywell International Inc. (Honeywell) TFE731-20 and TFE731-40 turbofan engines. This AD was prompted by two fan disks found with a manufacturing-caused flaw. This AD requires removing affected fan disks and replacing fan disks with a part eligible for installation. We are issuing this AD to address the unsafe condition on these products.

This AD requires replacement of the low- pressure compressor (LPC) case A-frame hollow locating pins. This AD was prompted by LPC case A-frame hollow locating pins that may have reduced integrity due to incorrect heat treatment. We are issuing this AD to correct the unsafe condition on these products.

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.

We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model DHC-8-401 and -402 airplanes. This AD was prompted by the discovery of cracking on two test spoiler power control unit (PCU) manifolds during testing by the manufacturer. This AD requires replacement of affected spoiler PCUs. We are issuing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for all Airbus Defense and Space S.A. Model CN-235, CN-235-100, CN-235-200, and CN-235-300 airplanes; and Model C-295 airplanes. This AD was prompted by reports of leakage of motorized cross-feed fuel valves. This AD requires repetitive inspections and operational checks of the affected fuel valves, and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.

The Federal Aviation Administration (FAA) is requesting public comment on a request by the County of Harnett of North Carolina, owner of the Harnett Regional Jetport, to change a portion of airport property from aeronautical to non-aeronautical use at the Harnett Regional Jetport. The request consists of approximately 2.49 acres to Piedmont Natural Gas Company, Inc. for use as a permanent utility easement for the installation of a gas line.

We are adopting a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) model Tay 620-15 turbofan engines. This AD requires reducing the maximum approved life limit. This AD was prompted by RRD recalculating the life limit for certain high-pressure compressor (HPC) stage 12 rotor disks. We are issuing this AD to correct the unsafe condition on these products.

This action modifies Class E airspace extending up to 700 feet above the surface at Wayne Municipal/Stan Morris Field (formally the Wayne Municipal Airport), Wayne, NE, to accommodate new standard instrument approach procedures for instrument flight rules (IFR) operations at the airport. This action is necessary due to the decommissioning of the Wayne non-directional radio beacon (NDB) serving the airport, and cancellation of the NDB approach. This action enhances the safety and management of IFR operations at the airport. The new airport name was not included in the NPRM and is being corrected. The geographic coordinates of the airport also are updated to be in concert with the FAA's aeronautical database.

We are adopting a new airworthiness directive (AD) for certain Rolls-Royce plc (RR) Trent XWB-75, Trent XWB-79, Trent XWB-79B, and Trent XWB-84, turbofan engines. This AD requires replacement of the low-pressure compressor (LPC) case support inboard pins. This AD was prompted by LPC case support inboard pins that may have reduced integrity due to incorrect heat treatment. We are issuing this AD to correct the unsafe condition on these products.

This action modifies the restricted areas at Fort Gordon, GA to further subdivide the vertical limits of the airspace. The designated altitudes for R-3004A and R-3004B are realigned and a new subarea, designated R-3004C, is established above R-3004B. The FAA is taking this action to allow for more efficient use of the airspace during periods when military activities only require restricted airspace below 3,500 feet MSL. The modifications are fully contained within the existing lateral and vertical boundaries of the restricted airspace.

This action proposes to modify Class E airspace extending upward from 700 feet above the surface at Fitch H. Beach Airport, Charlotte, MI. The FAA is proposing this action due to the decommissioning of the Lansing VHF omnidirectional range (VOR) and collocated tactical air navigation (TACAN), which provided navigation guidance for the instrument procedures to this airport. The VOR/TACAN is being decommissioned as part of the VOR Minimum Operational Network (MON) Program. This action would enhance safety and management of instrument flight rules (IFR) operations at this airport. Additionally, the geographic coordinates of the airport would be adjusted to coincide with the FAA's aeronautical database.

We are superseding Airworthiness Directive (AD) 2008-12-04, which applied to certain The Boeing Company Model 737-600, -700, -700C, -800, and -900 series airplanes. AD 2008-12-04 required various repetitive inspections to detect cracks along the chem-milled steps of the fuselage skin, and to detect missing or loose fasteners in the area of a certain preventive modification or repairs; replacement of the time-limited repair with a permanent repair, if applicable; and applicable corrective actions which would end certain repetitive inspections. This AD reduces the post-modification inspection compliance times, limits installation of the preventive modification to airplanes with fewer than 30,000 total flight cycles, and adds repetitive inspections for modified airplanes. This AD was prompted by an evaluation by the design approval holder (DAH) that indicated that the upper skin panel at the chem-milled step above the lap joint is subject to widespread fatigue damage (WFD) if the modification was installed after 30,000 total flight cycles. We are issuing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model EC225LP helicopters. This AD requires modifying the emergency lubrication system (EMLUB). This AD was prompted by two incidents of emergency ditching after there was a warning of a loss of oil pressure and a false EMLUB failure. The actions of this AD are intended to address an unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for all Alexander Schleicher GmbH & Co. Segelflugzeugbau Models ASH 25M and ASH 26E gliders. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as fatigue cracks found on the exhaust silencer. We are issuing this proposed AD to require actions to address the unsafe condition on these products.

This action modifies Class E airspace extending upward from 700 feet above the surface at Soldotna Airport, Soldotna, AK. After review of the airspace, the FAA found redesign necessary due to procedure modifications. This action also removes reference to the Soldotna non-directional radio beacon (NDB) in the legal description and updates the geographic coordinates of the airport. This action enhances the safety and management of IFR operations at the airport and of aircraft within the National Airspace System.

We propose to adopt a new airworthiness directive (AD) for certain Rolls-Royce Corporation (RRC) AE 3007A and AE 3007C model turbofan engines. This proposed AD was prompted by an updated analysis that lowered the life limit of fan wheels installed on the affected engines. This proposed AD would require removal of the affected fan wheel at new, lower life limits. We are proposing this AD to address the unsafe condition on these products.

This action proposes to modify the Class E airspace extending upward from 700 feet above the surface at Batten International Airport, Racine, WI, contained within the Milwaukee, WI, airspace description. The FAA is proposing this action due to the decommissioning of the Horlick VHF omnidirectional range (VOR), which provided navigation guidance for the instrument procedures to this airport. The VOR is being decommissioned as part of the VOR Minimum Operational Network (MON) Program.
