Federal Aviation Administration – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 767 airplanes. This proposed AD was prompted by a report of cracks on the forward entry door and forward service door cutout aft lower corner fuselage skin and bear strap. This proposed AD would require repetitive inspections for cracking at the affected area, 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 certain Airbus SAS Model A350-941 and A350-1041 airplanes. This AD is 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 AD requires 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 incorporated by reference. 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 MHI RJ Aviation ULC Model CL-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-2C11 (Regional Jet Series 550), CL-600-2D15 (Regional Jet Series 705), CL-600-2D24 (Regional Jet Series 900), and CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by a manufacturing quality escape concerning the installation of the Halon metering device on certain cargo fire extinguisher containers. This AD requires the inspection of cargo fire extinguisher container serial numbers and the replacement of the affected containers. This AD would also limit the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2022-18- 12, which applied to all Airbus SAS Model A330-841 and -941 airplanes. AD 2022-18-12 required installing serviceable engine electronic control (EEC) software or EEC units having the serviceable software, limiting certain parts installation configurations, and prior or concurrent modification of EEC software. This AD was prompted by a determination that engine crystal icing protection could be (temporarily) lost if an erroneous total pressure value is provided by the airplane system, which is addressed through EEC software. This AD continues to require certain actions in AD 2022-18-12 and requires adding new limitations for intermixing of certain EEC software standards and a new operational limitation for engines with certain EEC software installed, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also prohibits the installation of certain engines under certain conditions. The FAA is issuing 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 A320-214, A320-216, A320-251N, A320-271N, and A321-253NX airplanes. This proposed AD was prompted by a quality review of the forward cargo door frame-to-fuselage skin panel assembly identified several fastener holes that deviated from the manufacturing requirements. This proposed AD would require repetitive special detailed inspections of the affected area for discrepancies 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.

The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A330-202, A330-203, A330-223, A330-243, and A330-841 airplanes. This AD was prompted by a determination that the cold working process was partially completed on a certain circumferential joint. This AD requires modification of the circumferential joint, 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 is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) Model CF6-80C2B1F, CF6-80C2B2F, CF6-80C2B4F, CF6-80C2B5F, CF6-80C2B6F, CF6-80C2B7F, and CF6-80C2K1F engines. This AD was prompted by an uncontained engine fire and consequent manufacturer investigation, which revealed that certain bearings were installed improperly. This AD requires inspection of the magnetic chip detector (MCD) probe tip for metallic particles and, if necessary, removal of the engine from service. The FAA is issuing this AD to address the unsafe condition on these products.

This action extends the comment period for the NPRM titled ``Modernization of Special Airworthiness Certification,'' that was published on July 24, 2023. In that document, the FAA proposed to amend rules for the manufacture, certification, operation, maintenance, and alteration of light-sport aircraft. The proposed amendments would enable enhancements in safety and performance and would increase privileges under a number of sport pilot and light-sport aircraft rules. These enhancements include increasing suitability for flight training, limited aerial work, and personal travel. This proposed rule would expand what aircraft sport pilots may operate. The NPRM also proposed to amend the special purpose operations for restricted category aircraft; amend the duration, eligible purposes, and operating limitations for experimental aircraft; and add operating limitations applicable to experimental aircraft engaged in space support vehicle flights to codify statutory language. The FAA is extending the comment period for this NPRM to allow commenters additional time to analyze the proposed rule and prepare a response.

This action proposes to amend Very High Frequency Omnidirectional Range (VOR) Federal airway V-9 in Arkansas. V-9 currently exists as three separate route segments, and this proposed amendment would connect two of the route segments to create a longer contiguous airway.

This action proposes to amend Jet Route J-133 by revoking a portion of the airway and establishing Canadian Area Navigation Route (RNAV) Q-801 in the vicinity of Anchorage, AK. The proposed amendment of J-133 is due to the pending decommissioning of several Navigational Aids (NAVAID) that provide course guidance along the airway. The proposed establishment of RNAV route Q-801 serves as a mitigation to J- 133 and provides additional routing to the southeast for aircraft traveling to Canada or to the Pacific Northwest United States.

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.

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 to renew an information collection. The collection involves information from commercial air tour operators on the numbers and types of air tours over national park units. The information to be collected will be used by the FAA and the National Park Service to track air tour operations over national parks and as background information in the development of air tour management plans and voluntary agreements for purposes of addressing any potential significant impacts from commercial air tour operations on the natural or cultural resources or visitor experience at the parks.

The FAA is superseding Airworthiness Directive (AD) 2018-21- 11, which applied to all Pratt & Whitney Division (PW) Model PW4074D, PW4077D, PW4084D, PW4090, and PW4090-3 engines with a low-pressure compressor (LPC) fan hub, part number (P/N) 51B821 or P/N 52B521, installed. AD 2018-21-11 required performing repetitive eddy current inspections (ECIs) and fluorescent penetrant inspections (FPIs) for cracks in certain LPC fan hubs and removing LPC fan hubs from service that fail any inspection. Since the FAA issued AD 2018-21-11, the FAA determined that affected LPC fan hub assemblies can meet the published certificated life limit without the need for the required repetitive FPI inspections in AD 2018-21-11, and the repetitive ECI inspections require shortened intervals. Based on a report of another incident, the FAA determined that the unsafe condition is likely to exist or develop on additional LPC fan hub assemblies and PW model engines. This AD expands the applicability to include Model PW4074, PW4074D, PW4077, PW4077D, PW4084D, PW4090, and PW4090-3 engines with any part number LPC fan hub assembly installed and requires performing repetitive ECIs of the LPC fan hub assembly and, depending on the results of the inspections, removing the LPC fan hub assembly from service. 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 Dassault Aviation Model MYSTERE-FALCON 900, FALCON 900EX, FALCON 2000, and FALCON 2000EX airplanes. This AD was prompted by reports of the wing anti-icing (WAI) system leaking in the wing leading edge. This AD requires a one-time inspection of the WAI system, and corrective actions if necessary, 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.

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 to renew an information collection. The information collection involves a survey of uncrewed- aircraft-systems (UAS) operators within the United States. The information gathered through the survey's questionnaire on flight behavior and fleet characteristics is used to inform UAS rule making and guide investment in UAS research and infrastructure. This renewal seeks to continue the survey and improve the survey design to increase the generalization of survey results.

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS 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 proposed AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This proposed AD 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.

The FAA is superseding Airworthiness Directive (AD) 64-09-03, which applied to all de Havilland (type certificate now held by Viking Air Limited (Viking)) Model DHC-2 ``Beaver'' airplanes. AD 64-09-03 required inspecting the aileron mass balance weight arms for cracks and corrosion and replacing any damaged part. Since the FAA issued AD 64- 09-03, Transport Canada superseded its mandatory continuing airworthiness information (MCAI) to correct an unsafe condition on these products. This AD requires incorporating into the existing maintenance records for your airplane the actions and associated thresholds and intervals, including life limits, specified in a supplemental inspection and corrosion control manual for Model DHC-2 airplanes. This AD also requires completing all of the initial tasks identified in this manual and reporting certain corrosion findings to Viking. The actions in this supplemental inspection and corrosion control manual include the inspection of the aileron balance weight arms required by AD 64-09-03. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2020-24- 04, which applied to all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. AD 2020-24-04 required revising the existing airplane flight manual (AFM) to incorporate procedures for an approach with a localizer-based navigation aid, monitoring localizer raw data, calling out any significant deviations, and performing an immediate go around under certain conditions. This AD was prompted by the development of a modification to address the previously identified unsafe condition, and the identification of a separate unsafe condition where misleading vertical flight director (FD) guidance can be presented to the flightcrew under certain conditions. This AD continues to require the actions specified in AD 2020-24-04 and requires installing applicable software updates to the flight control module (FCM). Using updated software terminates the retained AFM requirement in this AD. The FAA is issuing this AD to address the unsafe condition on these products.

This action proposes to modify the Class E airspace extending upward from 700 feet above the surface and remove the Class E airspace extending upward from 1200 feet above the surface at Klawock Airport, Klawock, AK. Additionally, this action proposes administrative amendments to update the airport's existing Class E airspace legal description. These actions would support the safety and management of instrument flight rules (IFR) operations at the airport.

The FAA proposes to adopt a new airworthiness directive (AD) for all Bombardier, Inc., Model BD-100-1A10 airplanes. This proposed AD was prompted by reports from the supplier that some overheat detection 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 revising the existing airplane flight manual (AFM) to include procedures to prevent takeoff with an active bleed air leak annunciated while on the ground. This proposed AD would also require testing the overheat detection sensing elements, marking each serviceable sensing element with a witness mark, and replacing each nonserviceable part with a serviceable part. 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 is superseding Airworthiness Directive (AD) 2023-04- 16, which applied to certain Dassault Aviation Model FALCON 900EX airplanes. AD 2023-04-16 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2023-04- 16, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This AD continues to require the actions in AD 2023-04-16, and also 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.

The FAA is correcting a Notice of Proposed Rulemaking (NPRM) that published in the Federal Register. The NPRM proposed to issue an airworthiness directive (AD) that would apply to all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211-Trent 800 engines. As published, the docket number referenced throughout the NPRM is incorrect. This document corrects that error. In all other respects, the original document remains the same; however, for clarity, the FAA is republishing the entire proposed rule in the Federal Register.

The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.a. Model A119 and AW119 MKII helicopters. This AD was prompted by a report of an electrical failure of a starter-generator caused by a ruptured drive shaft. This AD requires visually inspecting the drive shaft of an affected starter-generator and depending on the results, performing a dye penetrant inspection. Depending on the results of the dye penetrant inspection, this AD requires replacing the starter-generator, 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.
