Public Notice for Waiver of Aeronautical Land Use Assurance; Astoria Regional Airport, Astoria, Oregon
Document Number: 2021-23433
Type: Notice
Date: 2021-10-28
Agency: Federal Aviation Administration, Department of Transportation
Notice is being given that the FAA is considering a proposal from the Port of Astoria Airport Director to change a certain portion of the airport from aeronautical use to non-aeronautical use at Astoria Regional Airport, Astoria, Oregon. The proposal consists of a portion of a parcel on the south side of the airfield.
Airworthiness Directives; General Electric Company Turbofan Engines
Document Number: 2021-23237
Type: Proposed Rule
Date: 2021-10-28
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) GEnx-1B and GEnx-2B model turbofan engines. This proposed AD was prompted by the manufacturer's report of two findings of sheared compressor discharge pressure (CDP) bolts during engine shop visits. This proposed AD would require initial and repetitive inspections of the CDP bolted joint and, depending on the findings, a piece part inspection of the stages 6-10 compressor rotor spool, CDP seal, and high-pressure turbine (HPT) rotor stage 1 disk. As a terminating action, this proposed AD would require operators to reassemble the CDP bolted joint using a specific torque wrench. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters
Document Number: 2021-23236
Type: Proposed Rule
Date: 2021-10-28
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters EC120B helicopters. This proposed AD was prompted by a report of geometrical non-conformities in the tail rotor blade (TRB) root section discovered during an accident investigation of a Model EC130B helicopter. Due to the similarity of design and production requirements, certain TRBs for the Model EC120B helicopters were inspected and geometrical non-conformities were also found. This proposed AD would require an inspection (dimensional check) to verify conformity, and replacement of certain TRBs if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). This proposed AD would also prohibit rework, repair, or modification of affected parts in the affected area of the TRB assembly root. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters
Document Number: 2021-23233
Type: Proposed Rule
Date: 2021-10-28
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model EC120B helicopters. This proposed AD was prompted by a report of corrosion found on the external tail boom skin, under the Very High Frequency (VHF) antenna. This proposed AD would require inspecting the tail boom at the VHF antenna attachments and depending on the results, repairing or modifying the tail boom skin, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2021-23218
Type: Proposed Rule
Date: 2021-10-28
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by reports of a missing shim at a joint common to the main torque box (MTB) skin panel and rear spar root fitting. This proposed AD would require inspecting the MTB skin panel and rear spar root fitting for cracking and delamination, and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
Proposed Modification of Class D and Class E Airspace, and Proposed Establishment of Class E Airspace; Southwest Oregon Regional Airport, OR
Document Number: 2021-23217
Type: Proposed Rule
Date: 2021-10-28
Agency: Federal Aviation Administration, Department of Transportation
This action proposes to modify the Class D and Class E surface airspace at Southwest Oregon Regional Airport, North Bend, OR. It also proposes to modify the Class E airspace by establishing an area that is designated as an extension to a Class D or Class E surface area, and to modify the Class E airspace extending upward from 700 feet above the surface. Lastly, this action proposes to remove navigational aids (NAVAID) from the legal description of the Class E2 and Class E5 text headers, and to update the Class D, Class E2, and Class E5 airspace legal descriptions and establish Class E4 airspace. This action would ensure the safety and management of instrument flight rules (IFR) operations at the airport.
Airworthiness Directives; Airbus SAS Airplanes
Document Number: 2021-23216
Type: Proposed Rule
Date: 2021-10-28
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A318 series; A319-111, -112, -113, -114, - 115, -131, -132, -133, -151N, and -153N; A320 series; and A321 series airplanes. This proposed AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; International Aero Engines AG Turbofan Engines
Document Number: 2021-23180
Type: Proposed Rule
Date: 2021-10-28
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede Airworthiness Directive (AD) 2021-11-15, which applies to certain International Aero Engines AG (IAE) V2500 model turbofan engines. AD 2021-11-15 requires performance of an ultrasonic inspection (USI) of the high-pressure turbine (HPT) 1st-stage disk and HPT 2nd-stage disk and, depending on the results of the inspections, replacement of the HPT 1st-stage disk or HPT 2nd-stage disk. Since the FAA issued AD 2021-11-15, the FAA determined the need to clarify the compliance time for inspection of any HPT 1st-stage disk or HPT 2nd-stage disk that is installed on a low-thrust model engine but had been previously operated on a high-thrust model engine. This proposed AD would require performance of a USI of the HPT 1st-stage disk and HPT 2nd-stage disk and, depending on the results of the inspections, replacement of the HPT 1st-stage disk or HPT 2nd-stage disk. The FAA is proposing this AD to address the unsafe condition on these products.
Proposed Establishment of United States Area Navigation (RNAV) Route T-417; Tok Junction, AK
Document Number: 2021-23176
Type: Proposed Rule
Date: 2021-10-28
Agency: Federal Aviation Administration, Department of Transportation
This action proposes to establish United States Area Navigation (RNAV) route T-417 in the vicinity of Tok Junction, AK in support of a large and comprehensive T-route modernization project for the state of Alaska.
