Federal Aviation Administration June 2023 – Federal Register Recent Federal Regulation Documents

This action proposes to amend Very High Frequency (VHF) Omnidirectional Range (VOR) Federal airway V-36 and establish Area Navigation (RNAV) route T-675 in the northcentral United States. The airway amendments are necessary due to the planned decommissioning of the Wawa, Ontario (ON), Canada, VOR navigational aid (NAVAID). This action is in support of NAV CANADA's NAVAID Modernization Program within Canada.

The FAA is superseding Airworthiness Directive (AD) 2022-25- 16, which applied to all ATRGIE Avions de Transport R[eacute]gional Model ATR42-200, -300, and -320 airplanes. AD 2022-25-16 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD continues to require certain actions in AD 2022-25-16 and requires 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 incorporated by reference (IBR). The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD requires 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 incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

This action proposes to amend six United States Area Navigation (RNAV) Q-routes in the eastern United States. This action supports the Northeast Corridor Atlantic Coast Routes (NEC ACR) Optimization Project to improve the efficiency of the National Airspace System (NAS).

The FAA is superseding Airworthiness Directive (AD) 2017-06- 07, which applied to all Airbus SAS Model A330-200 Freighter, -200, and -300 series airplanes; and A340-200, -300, -500, and -600 series airplanes. AD 2017-06-07 required identification of potentially affected inboard flap parts, a one-time eddy current inspection to identify which material the parts are made of, and, depending on findings, replacement with serviceable parts. This AD was prompted by a determination that, even if affected inboard flaps were not installed on airplanes during production, affected inboard flaps could be installed on airplanes as spare parts. This AD continues to require the actions in AD 2017-06-07, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also reduces the allowance for the installation of affected parts under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.

This action proposes to amend the Class E airspace at Ruston, LA. The FAA is proposing this action as the result of an airspace review caused by the decommissioning of the Ruston non directional beacon (NDB). The geographic coordinates of the airport would also be updated to coincide with the FAA's aeronautical database.

The FAA is superseding Airworthiness Directive (AD) 2019-24- 13, which applied to certain Airbus SAS Model A318 series airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2019-24-13 required repetitive high-frequency eddy current (HFEC) inspections for cracking of a stiffener of a certain lateral window frame, and applicable related investigative and corrective actions. This AD was prompted by a determination that certain inspection times need to be revised. This AD retains the requirements of AD 2019-24-13, with amended compliance times, 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.

This action establishes Class E airspace at San Saba, TX. This action supports the establishment of new public instrument procedures.

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval for a new information collection. The purpose of this notice is to allow 60 days for public comment. The FAA proposes collecting information related to requests for certificate of waivers to operate Unmanned Aircraft Systems (UAS) in deviation from the normal operating rules. The FAA will use the collected information to make determinations whether to authorize or deny the requested operation of UAS. The proposed information collection is necessary to issue such authorizations or denials consistent with the FAA's mandate to ensure safe and efficient use of national airspace.

The FAA is removing Airworthiness Directive (AD) 92-02-14, which applied to certain Airbus SAS Model A320 series airplanes. AD 92- 02-14 required inspection for correct installation of the flexible control cables on the overwing emergency escape slides. The FAA issued AD 92-02-14 to prevent failure of the overwing emergency escape slides to deploy, which would compromise use of the exit during an emergency. Since the FAA issued AD 92-02-14, no new occurrences of incorrect cable installations have been reported, and existing maintenance activities are adequate to prevent new occurrences. Therefore, the FAA has determined that AD 92-02-14 is no longer necessary. Accordingly, AD 92- 02-14 is removed.

This rule amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide for the safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

The FAA proposes to adopt a new airworthiness directive (AD) for certain De Havilland Aircraft of Canada Limited Model DHC-8-401 and -402 airplanes. This proposed AD was prompted by reports of the main landing gear (MLG) aft door not opening when using the alternate extension system. This proposed AD would require a one-time inspection of the spring box assembly, repetitive inspections of the cam assembly and alternate release cable assembly, corrective actions if necessary, and a replacement of certain alternate release cable assemblies. In addition, this proposed AD would also require certain aircraft maintenance manuals tasks when installing the cam assembly or alternate release cable assembly. 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 certain Airbus SAS Model A350-941 and A350-1041 airplanes. This proposed AD was prompted by reports that excessively deep spot faces on the front engine mounting bolt holes on the wing pylon were detected on the production line. This proposed AD would require a one-time inspection for clash (interference) of the three front engine mounting bolt holes on both the left and right wing pylons, and, depending on findings, accomplishment of applicable corrective actions, 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.

This action amends Very High Frequency (VHF) Omnidirectional Range (VOR) Federal airway V-376 by removing the Nottingham, MD (OTT), VOR/Tactical Air Navigational System (VORTAC) from the route description and replacing it with the Casanova, VA (CSN), VORTAC. This action is required due to the planned decommissioning of the Nottingham, MD (OTT), VORTAC as part of FAA's VOR Minimum Operational Network (MON) program. This action does not change the alignment, altitudes, or operating requirements of V-376. In addition, language is added to exclude the airspace within restricted areas R-6601A, R-6601B, and R-6601C.
