The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD- 500-1A11 airplanes. This proposed AD was prompted by reports of mechanical wear damage on the motive flow fuel-feed tubes that were secured by bonding clamps and clamp blocks inside the collector tank. This proposed AD would require repetitive operational checks of the gravity cross flow shut-off valve and, for certain airplanes, a one- time inspection of the motive flow fuel-feed tubes at the clamp blocks location, and corrective action if necessary, as specified in a Transport Canada AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

The FAA has determined to extend through October 28, 2023, the limited, conditional waiver of the minimum usage requirement that applies to Operating Authorizations or ``slots'' at John F. Kennedy International Airport (JFK), New York LaGuardia Airport (LGA), and Ronald Reagan Washington National Airport (DCA) due to post-pandemic effects on Air Traffic Controller (ATC) staffing at the New York Terminal Radar Approach Control (TRACON) facility (N90) the FAA has already made available through September 15, 2023. Carriers will be permitted to voluntarily turn in up to 10 percent of their slots held at JFK and LGA as well as impacted slots at DCA for the period from September 16, 2023, through October 28, 2023. In addition, the FAA has determined to extend through October 28, 2023, the limited policy for prioritizing returned operations at Newark Liberty International Airport (EWR) due to post-pandemic effects on ATC staffing at N90 for purposes of establishing a carrier's operational baseline in the next corresponding season. Carriers will be permitted to voluntarily turn in up to 10 percent of their approved operating timings at EWR for the period from September 16, 2023, through October 28, 2023. These extensions through October 28, 2023, are available on the same conditions and limitations as the relief that the FAA already has announced through September 15, 2023. Carriers seeking to take advantage of this relief must identify the slots and approved operating timings they wish to return to the FAA before September 2, 2023.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. This proposed AD was prompted by reports from the supplier that sensing elements of the bleed air leak detection system were manufactured with insufficient salt fill, which can result in an inability to detect hot bleed air leaks. This proposed AD would require testing of all affected overheat detection sensing elements of the bleed air leak detection system, and replacement if necessary. 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 supersede Airworthiness Directive (AD) 2020-23-10, which applies to certain Dassault Aviation Model FAN JET FALCON and FAN JET FALCON SERIES C, D, E, F, and G airplanes. AD 2020- 23-10 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2020-23-10, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would continue to require the actions in AD 2020-23-10 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.

The FAA proposes to adopt a new airworthiness directive (AD) for certain ATRGIE Avions de Transport R[eacute]gional Model ATR42- 500 and ATR72-212A airplanes. This proposed AD was prompted by reports of loose fasteners and cracks in the horizontal stabilizer (HS) left- and right-hand leading edge lateral ribs, the box in between, the center box upper panel, and HS forward back-up fitting. This proposed AD would require an inspection of the HS affected areas for discrepancies and applicable corrective action, as specified in a European Union Aviation Safety Agency (EASA), which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

This action proposes to amend Class D airspace, remove Class D airspace, amend Class E surface airspace, and amend Class E airspace designated as an extension to a Class D surface area at Capital City Airport, Harrisburg, PA. In addition, this action would make administrative updates.

The Secretary of Transportation, as represented by the Maritime Administration (MARAD), is authorized to issue coastwise endorsement eligibility determinations for foreign-built vessels which will carry no more than twelve passengers for hire. A request for such a determination has been received by MARAD. By this notice, MARAD seeks comments from interested parties as to any effect this action may have on U.S. vessel builders or businesses in the U.S. that use U.S.-flag vessels. Information about the requestor's vessel, including a brief description of the proposed service, is listed below.

This action proposes to amend Very High Frequency Omnidirectional Range (VOR) Federal airways V-44, V-128, and V-493, and United States Area Navigation (RNAV) routes T-315 and T-323. The FAA is proposing this action due to the planned decommissioning of the VOR portion of the York, KY (YRK), VOR/Tactical Air Navigation (VORTAC) navigational aid (NAVAID). The York VOR is being decommissioned in support of the FAA's VOR Minimum Operational Network (MON) program.
