Federal Aviation Administration December 6, 2022 – Federal Register Recent Federal Regulation Documents

The FAA proposes to supersede Airworthiness Directive (AD) 2020-22-16, AD 2021-16-01, and AD 2022-04-03, which apply to certain Airbus SAS Model A318, A320 and A321 series airplanes; and Model A319- 111, -112, -113, -114, -115, -131, -132, -133, -151N, and -153N airplanes. AD 2020-22-16, AD 2021-16-01, and AD 2022-04-03 require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2020-22-16, AD 2021-16-01, and AD 2022-04-03, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would continue to require the actions in AD 2020-22-16, AD 2021-16-01, and AD 2022-04-03, and would require revising the existing maintenance or inspection program, as applicable, to incorporate additional new or more restrictive airworthiness limitations, 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.

These special conditions are issued for the Airbus Model A321neoXLR airplane. This airplane will have a novel or unusual design feature when compared to the technology envisaged by the airworthiness standards for transport category airplanes. This design feature is an integral rear center tank (RCT). The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A318 series airplanes; Model A319 series airplanes; Model A320-211, -212, -214, -216, -231, -232, -233, -251N, - 252N, -253N, -271N, -272N, and -273N airplanes; and Model A321 series airplanes. This proposed AD was prompted by a report that certain overheat detection system (OHDS) sensing elements installed at certain positions might not properly detect thermal bleed leak events due to a quality escape during the manufacturing process. This proposed AD would require a one-time detailed inspection of each affected part installed at an affected position and, depending on the findings, replacement; and would prohibit the installation of affected parts at affected positions, 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.

This action revokes Colored Federal airway Amber 6 (A-6) due to the planned decommissioning of the St Marys, AK (SMA), Non- Directional Beacon (NDB) in the vicinity of St. Mary's, AK.

The FAA proposes to rule and invite public comment on the release and sale of a 5,457 square foot parcel of land at the Colorado Air and Space Port.

The FAA proposes to supersede Airworthiness Directive (AD) 2021-08-19, which applies to all The Boeing Company Model 787-8, -9, and -10 airplanes. AD 2021-08-19 requires repetitive general visual inspections for disengaged or damaged decompression panels of the bilge barriers located in the forward and aft cargo compartments, reinstallation of disengaged but undamaged panels, and replacement of damaged panels. Since the FAA issued AD 2021-08-19, new procedures for changing or replacing the bilge barrier assembly in the forward cargo compartment have been developed. This proposed AD would retain the requirements of AD 2021-08-19 and require changing or replacing the bilge barrier assembly in the forward and aft cargo compartments, which would terminate the repetitive inspections. The FAA is proposing this AD to address the unsafe condition on these products.

This action amends VHF Omnidirectional Range (VOR) Federal airway V-356 by revoking the airway segment between the FIDLE and ELORE Fixes. The FAA is taking this action due to the Mile High, CO, VOR/ Tactical Air Navigation (VORTAC) signal coverage supporting the airway segment having been determined to be unusable below 18,000 feet mean sea level (MSL) during flight inspection.

This action revokes Colored Federal airway Green 7 (G-7) due to the pending decommissioning of the Fort Davis, AK (FDV), Non- Directional Beacon (NDB) in the vicinity of Nome, AK.

This action revokes Colored Federal airway Blue 79 (B-79) in the vicinity of Annette Island, AK, due to the planned decommissioning of the Nichols, AK (ICK), Non-Directional Beacon (NDB).

This action revokes Colored Federal airway Green 15 (G-15) due to the planned decommissioning of the St Marys, AK (SMA), and Takotna River, AK (VTR), Non-Directional Beacons (NDBs).
