Federal Aviation Administration – Federal Register Recent Federal Regulation Documents

On October 17, 2023, the Federal Aviation Administration (FAA) published the subject direct final rule in the Federal Register, confirmed on November 29, 2023. In that direct final rule, the FAA redesignated two paragraphs in one section of the Code of Federal Regulations but failed to amend cross-references to those paragraphs. This document corrects those errors.

The FAA proposes to adopt a new airworthiness directive (AD) for certain MHI RJ Aviation ULC Model CL-600-2D15 (Regional Jet Series 705) and CL-600-2D24 (Regional Jet Series 900) airplanes. This proposed AD was prompted by a report that torque wrenches used during production installation of bulkhead fittings on the oxygen lines of the flight crew oxygen mask stowage boxes and adapter fitting on the oxygen pressure gauge were out of calibration during production installation, which resulted in a higher torque level setting than required. This proposed AD would require replacement of the affected oxygen line fittings, 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.

This action proposes to modify the Class E airspace designated as a surface area, modify the airspace designated as an extension to a Class E surface area, modify the Class E airspace extending upward from 700 feet above the surface, and remove the Class E airspace extending upward from 1,200 feet above the surface at Bishop Airport, Bishop, CA. These actions would support the safety and management of instrument flight rules (IFR) operations at the airport.

The FAA is superseding Airworthiness Directive (AD) 2010-18- 06, which applied to all GA8 Airvan (Pty) Ltd Model GA8 and GA8-TC320 airplanes. AD 2010-18-06 required inspections and a minor design change to the forward slide of the cargo door with corrective action as necessary. Since the FAA issued AD 2010-18-06, the Civil Aviation Safety Authority (CASA), which is the aviation authority for Australia, superseded the previous CASA Australia AD to incorporate more detailed inspections and additional modifications as specified in updated service information published by the manufacturer. This AD was prompted by reports of in-flight cargo door separation. This AD requires inspections and rework (modifications) of the cargo door with corrective action as necessary. The FAA is issuing this AD to address the unsafe condition on these products.

This AD was prompted by a report of multiple aborted takeoffs and air turn-backs (ATBs) caused by high-pressure compressor (HPC) stall, which was induced by high levels of non-synchronous vibration (NSV). Additional manufacturer investigation revealed that wear on the No. 3 bearing spring finger housing can lead to high levels of NSV. This AD requires initial and repetitive calculations of the levels of NSV, inspection of the stage 2 high-pressure turbine (HPT) nozzle assembly honeycomb and HPT stator stationary seal honeycomb and, depending on the results of the calculations and inspections, replacement of certain parts. This AD also requires replacement of certain No. 3 bearing spring finger housings at a certain time. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain International Aero Engines, LLC (IAE) Model PW1124G1-JM, PW1127G-JM, PW1127GA-JM, PW1129G-JM, PW1130G-JM, PW1133G-JM, and PW1133GA-JM engines. This AD was prompted by a report that certain high-pressure compressor (HPC) 2nd stage rotors and HPC 4th stage rotors have potentially degraded knife-edge seals and abrasive coating of the rear wing 4th stage rotor due to having been cleaned in alkaline solution without masking the knife-edge seal coating. Operating in this condition could result in material degradation and fracture of the HPC 2nd stage rotor and HPC 4th stage rotor. This AD requires replacement of certain HPC 2nd stage rotors and HPC 4th stage rotors. 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 Hamilton Sundstrand Corporation (Hamilton Sundstrand) Model 14SF-7, 14SF-15, and 14SF-23 propellers.

These actions support Next Generation Air Transportation System (NextGen) which provides a modern RNAV route structure to improve the efficiency of the National Airspace System (NAS).

The FAA is withdrawing the Notice of Proposed Rulemaking (NPRM) published in the Federal Register on June 15, 2023, proposing to amend Very High Frequency Omnidirectional Range (VOR) Federal Airway V- 469; and to revoke VOR Federal Airways V-164, V-423, and V-576; due to the planned decommissioning of the Williamsport, PA (FQM), VOR/Distance Measuring Equipment (DME); Stonyfork, PA (SFK), VOR/DME; Danville, VA (DAN), VOR; Hancock, NY (HNK), VOR/DME; and Delancey, NY (DNY), VOR/ DME.

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 various helicopters modified by certain supplemental type certificates (STCs) that approve the installation of an emergency float kit or an emergency float with liferaft kit. This proposed AD was prompted by the results of an accident investigation and subsequent reports of difficulty pulling the emergency float kit float activation handle installed on the pilot cyclic. This proposed AD would require repetitively inspecting the pull force on the float activation handle and, depending on the results, accomplishing corrective actions. For certain model helicopters, this proposed AD would also require removing from service and replacing certain part-numbered float inflation reservoirs (reservoirs) and pull cable assemblies (cables) with certain other part-numbered reservoirs and cables. Finally, this proposed AD would prohibit installing certain part-numbered reservoirs and cables on certain helicopters. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2023-18-09, which applies to certain Dassault Aviation Model FALCON 900EX airplanes. AD 2023-18-09 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2023-18-09, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would continue to require certain actions in AD 2023-18-09 and would require 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 proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
