Amendment of VOR Federal Airways V-17, V-18, V-62, V-94, V-163, and V-568 in the Vicinity of Glen Rose, TX
This action amends VHF Omnidirectional Range (VOR) Federal airways V-17, V-18, V-62, V-94, V-163, and V-568 in the vicinity of Glen Rose, TX. The modifications are necessary due to the planned decommissioning of the VOR portion of the Glen Rose, TX, VOR/Tactical Air Navigation (VORTAC) navigation aid (NAVAID), which provides navigation guidance for portions of the affected airways. The Glen Rose VOR is being decommissioned as part of the FAA's VOR Minimum Operational Network (MON) program.
Airworthiness Directives; Airbus SAS Airplanes
The FAA proposes to supersede Airworthiness Directive (AD) 2018-17-05, which applies to all Airbus SAS Model A350-941 and -1041 airplanes. AD 2018-17-05 requires a check of the insulation resistance of the direct drive solenoid valve (DDSOV) of each affected electro- hydrostatic actuator (EHA) and applicable corrective actions. Since the FAA issued AD 2018-17-05, it has been determined that certain EHA part numbers can be modified and re-identified as specified in European Union Aviation Safety Agency (EASA) AD 2019-0301, dated December 12, 2019, which would inadvertently remove certain part numbers from the applicability in other EHA-related ADs. This proposed AD would require a check of the insulation resistance of the DDSOV of each affected EHA and applicable corrective actions, and modifying or replacing certain EHAs, as specified in two EASA ADs, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A300 F4-600R series airplanes. This proposed AD was prompted by a report of damaged main deck cargo crossbeams on the right-hand side, between certain frame locations. This proposed AD would require repetitive detailed inspections of the affected main deck cargo crossbeams for any damage, and depending on findings, accomplishment of applicable corrective actions, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. This proposed AD would also provide optional terminating actions for the repetitive detailed inspections. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; AVOX System Inc. (formerly Scott Aviation) Oxygen Cylinder and Valve Assemblies; and Oxygen Valve Assemblies
The FAA proposes to adopt a new airworthiness directive (AD) for certain AVOX System Inc. (formerly Scott Aviation) oxygen cylinder and valve assemblies; and oxygen valve assemblies; installed on but not limited to various transport airplanes. This proposed AD was prompted by reports of cylinder and valve assemblies having oxygen leakage from the valve assembly vent hole, caused by the absence of a guide that maintains appropriate spacing between certain parts. This proposed AD would require an inspection of the oxygen valve assemblies, and oxygen cylinder and valve assemblies, to determine the serial number of the valve, cylinder, and entire assembly. For assemblies and parts with certain serial numbers, this AD would require a detailed inspection for correct spacing of the gap between the bottom of the packing retainer and top of the valve body on the assemblies, and replacement of assemblies having unacceptable gaps. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
The FAA is revising an earlier proposal for certain The Boeing Company Model 737-600, -700, -700C, -800, and -900 series airplanes. This action revises the notice of proposed rulemaking (NPRM) by revising certain inspections to provide the correct thickness callouts for the fuselage skin and bear strap. The FAA is proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these actions would impose an additional burden over that in the NPRM, the FAA is reopening the comment period to allow the public the chance to comment on these changes.
