Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG (Type Certificate Previously Held by Rolls-Royce plc) Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd. & Co KG (RRD) Trent XWB-75, XWB- 79, XWB-79B, and XWB-84 model turbofan engines. This AD was prompted by analysis by the manufacturer of the low-pressure compressor (LPC) outlet guide vane (OGV) assembly and LPC OGV outer mount ring assembly. The analysis predicted that when the front engine mount is in the fail- safe condition, the most highly stressed LPC OGV outer mount ring assembly has a life that could be substantially less than one shop visit interval. This AD requires initial and repetitive inspections of the LPC OGV outer mount ring assembly and, depending on the results of the inspections, possible replacement of the LPC OGV outer mount ring assembly. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model EC120B helicopters. This AD was prompted by a report that a changed manufacturing process for the tail rotor blades (TRB) was implemented, affecting the structural characteristics of the blades and generating a new part number for these blades. This AD requires re-identifying each affected TRB having a certain part number and serial number and establishing a life limit for the new part numbers. This AD also prohibits installation of any affected TRB identified with the old part number on any helicopter. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
The FAA is withdrawing a supplemental notice of proposed rulemaking (SNPRM) that proposed to adopt a new airworthiness directive (AD) that would have applied to all Airbus SAS Model A330-200, A330-200 Freighter, A330-300, A340-200, A340-300, A340-500, and A340-600 series airplanes. The SNPRM would have required repetitive tests of affected free fall actuators (FFAs), and replacement of any affected FFA that fails a test with a serviceable FFA; as specified in European Union Aviation Safety Agency (EASA) AD 2019-0164, dated July 11, 2019 (``EASA AD 2019-0164''). Since issuance of the SNPRM, the FAA has determined that the SNPRM does not adequately address the identified unsafe condition. Accordingly, the SNPRM is withdrawn.
Airworthiness Directives; Airbus SAS Airplanes
The FAA proposes to supersede Airworthiness Directive (AD) 2017-18-17, which applies to all Airbus SAS Model A300 B4-603, A300 B4- 620, A300 B4-622, A300 B4-605R, A300 B4-622R, A300 F4-605R, A300 F4- 622R, and A300 C4-605R Variant F airplanes. AD 2017-18-17 requires modifying certain fuselage frames and a repair on certain modified airplanes. Since AD 2017-18-17 was issued, the FAA has determined that, for certain airplanes, a rotating probe inspection must be performed prior to oversizing of the open-holes, and consequently more work is necessary for airplanes that have previously been modified. This proposed AD would continue to require the actions in AD 2017-18-17. This proposed AD would also require, for certain airplanes, an inspection to determine if rotating probe inspections were performed prior to oversizing of the open-holes, and repair if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; General Electric Company Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) GEnx-1B64/P2, -1B67/P2, - 1B70/P2, -1B70C/P2,-1B70/75/P2, -1B74/75/P2, -1B76/P2, -1B76A/P2, and GEnx-2B67/P model turbofan engines. This proposed AD was prompted by the detection of melt-related freckles in the billet, which may reduce the life limits of certain high-pressure turbine (HPT) rotor stage 2 disks and a certain stages 6-10 compressor rotor spool. This proposed AD would require the removal of certain HPT rotor stage 2 disk and the removal of a certain stages 6-10 compressor rotor spool before reaching their new life limits. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; General Electric Company Turbofan Engines
The FAA proposes to supersede Airworthiness Directive (AD) 2018-15-04, which applies to certain General Electric Company (GE) CF6- 80A, CF6-80A1, CF6-80A2, CF6-80A3, CF6-80C2A1, CF6-80C2A2, CF6-80C2A3, CF6-80C2A5, CF6-80C2A5F, CF6-80C2A8, CF6-80C2B1, CF6-80C2B1F, CF6- 80C2B2, CF6-80C2B2F, CF6-80C2B4, CF6-80C2B4F, CF6-80C2B5F, CF6-80C2B6, CF6-80C2B6F, CF6-80C2B6FA, CF6-80C2B7F, CF6-80C2D1F, CF6-80C2L1F, and CF6-80C2K1F model turbofan engines. AD 2018-15-04 requires ultrasonic inspection (UI) of high-pressure turbine (HPT) stage 1 and stage 2 disks. Since we issued AD 2018-15-04, GE determined the need to expand the population of affected disks. This proposed AD would retain the required inspections while expanding the population of affected disks. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Leonardo S.p.a. Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for Leonardo S.p.a. (Leonardo) Model AB139 and AW139 helicopters. This proposed AD would require removing certain main gearbox (MGB) input modules from service. This proposed AD was prompted by the discovery that a batch of duplex bearings, which are installed on the MGB input modules, are defective. The actions of this proposed AD are intended to address an unsafe condition on these products.
Notice of Release of Land Affecting Federal Grant Assurance Obligations at Salinas Municipal Airport, Salinas, Monterey County, California
The Federal Aviation Administration (FAA) is considering a proposal and invites public comment to change a portion of the airport from aeronautical use to non-aeronautical use at Salinas Municipal Airport (SNS), Salinas, Monterey County, California. The proposal consists of one parcel containing 13.25 acres of airport land, located outside of the airfield, south of Airport Boulevard, between Mercer Way and Skyway Boulevard, and north of Mortensen Avenue.
Proposed Revocation, Establishment, and Amendment of Class E Airspace; Multiple Texas Towns
This action proposes to revoke the Class E airspace extending upward from 700 feet above the surface at Ambassador Field, Big Sandy, TX; and establish and amend Class E airspace extending upward from 700 feet above the surface at several Texas airports. The FAA is proposing this action as the result of airspace reviews caused by the decommissioning of the Quitman VHF omnidirectional range (VOR) navigation aid, which provided navigation information for the instrument procedures these airports, as part of the VOR Minimum Operational Network (MON) Program. The names and geographic coordinates of several airports would also be updated to coincide with the FAA's aeronautical database.
Amendment of Class D and E Airspace; Dallas-Fort Worth, Fort Worth, and Stephenville, TX
This action amends the Class D airspace at Fort Worth Spinks Airport, Fort Worth, TX, and the Class E airspace extending upward from 700 feet above the surface at Bourland Field, Fort Worth, TX, and Mesquite Metro Airport, Mesquite, TX, and Stephenville Clark Regional Airport, Stephenville, TX. These actions are the result of airspace reviews caused by the decommissioning of the Glen Rose VHF omnidirectional range (VOR) navigation aid as part of the VOR Minimum Operational Network (MON) Program. The geographic coordinates and names of several airports are also being updated to coincide with the FAA's aeronautical database.
Amendment of Class D Airspace and Amendment and Revocation of the Class E Airspace; Multiple Texas Towns
This action affects several airports in Texas by amending Class D airspace and Class E surface airspace; revoking Class E airspace designated as an extension to a Class E surface area; amending Class E airspace extending upward from 700 feet above the surface; and removing Class E airspace extending upward from 700 feet above the surface. This action is due to airspace reviews caused by the decommissioning of the Hobby and Temple VHF omnidirectional range (VOR) navigation aids as part of the VOR Minimum Operational Network (MON) Program. The geographic coordinates and names of several airports would also be updated to coincide with the FAA's aeronautical database.
