Federal Aviation Administration September 8, 2022 – Federal Register Recent Federal Regulation Documents

The FAA is superseding Emergency Airworthiness Directive (AD) 2022-18-51, which applied to all Airbus SAS Model A330-841 and -941 airplanes. Emergency AD 2022-18-51 required revising the existing airplane flight manual (AFM) to incorporate additional limitations prohibiting takeoff for certain airplane configurations; specified airplane dispatch restrictions using certain provisions of the A330 master minimum equipment list (MMEL) or amending the existing FAA- approved operator's minimum equipment list (MEL); and required obtaining and accomplishing instructions following certain maintenance messages. Since the FAA issued Emergency AD 2022-18-51, additional instructions and maintenance procedures have been developed to address failures of the high pressure valve (HPV). This AD continues to require the actions specified in Emergency AD 2022-18-51, and also requires maintenance actions, including an HPV seal integrity test, repetitive replacement of the HPV clips, revision of the existing AFM, and implementation of updates to the FAA-approved operator's MEL, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2021-07-09, which applies to all The Boeing Company Model 747-100, 747- 100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes. AD 2021-07-09 requires repetitively inspecting all trim air diffuser ducts or sidewall riser duct assemblies (collectively referred to as TADDs) for damage, including repetitive structural inspections of the center fuel tanks for damage, and applicable on-condition actions. Since the FAA issued AD 2021-07-09, the agency has determined that the existing requirements do not adequately address the unsafe condition. This proposed AD would continue to require repetitive inspections of the TADDs for damage with revised compliance times, and repair if applicable. This proposed AD would also require repetitive replacement of the TADDs and would remove the structural inspections of the center fuel tanks. This proposed AD would also prohibit the installation of affected parts. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD was prompted by a report indicating that a crack was found in one of the holes of the wing rear spar lower chord at the main landing gear (MLG) aft fitting at a certain wing buttock line (WBL). This proposed AD would require repetitive open hole high frequency eddy current (HFEC) inspections or surface HFEC and ultrasonic (UT) inspections for cracking of the wing rear spar lower chord at the MLG aft fitting at a certain WBL, and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. This AD was prompted by review of maintenance instructions that showed conflicting methods of recording torque cycles for certain parts. This AD requires recalculating the torque cycles of certain parts and updating log cards; removing certain other parts from service; and applying an operational restriction on certain parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also requires incorporating the re-calculated life limits into existing maintenance records. The FAA is issuing this AD to address the unsafe condition on these products.

This action amends 14 CFR part 71 relating to airspace designations to reflect the approval by the Director of the Federal Register of the incorporation by reference of FAA Order JO 7400.11G, Airspace Designations and Reporting Points. This action also explains the procedures the FAA will use to amend the listings of Class A, B, C, D, and E airspace areas; air traffic service routes; and reporting points incorporated by reference.

This action removes VHF Omnidirectional Range (VOR) Federal Airways V-31, V-447, and V-475 in support of the FAA's VOR Minimum Operation Network (MON) Program.

This action amends four jet routes and removes eight jet routes in the eastern United States. This action is associated with the Northeast Corridor Atlantic Coast Route Project and supports the VHF Omnidirectional Range (VOR) Minimum Operational Network (MON) to improve the efficiency of the National Airspace System (NAS) and reduce dependency on ground-based navigational systems.

The FAA is superseding Airworthiness Directive (AD) 2020-22- 03, which applied to all Airbus SAS Model A330-200, -200 Freighter, and -300 series airplanes. AD 2020-22-03 required revising the existing airplane flight manual (AFM) to incorporate procedures to be applied if an engine bleed over-temperature occurs when the associated engine bleed valve is jammed open, and provided for the optional embodiment of updated flight warning computer (FWC) software, which terminated the AFM revision. This AD was prompted by the development of new maintenance actions and software related to over-temperature failure conditions. This AD continues to require the actions specified in AD 2020-22-03, requires accomplishing the new maintenance tasks and corrective actions, and mandates embodiment of the updated FWC software for certain airplanes, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also prohibits the installation of affected FWC software. The FAA is issuing this AD to address the unsafe condition on these products.

The Federal Aviation Administration (FAA) announces its determination that the noise exposure map submitted by Laredo International Airport is in compliance with applicable statutory and regulatory requirements.
