Federal Aviation Administration March 2024 – Federal Register Recent Federal Regulation Documents

The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by reports 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 AD requires maintenance records verification, and if an affected part is installed, would prohibit the use of certain Master Minimum Equipment List (MMEL) items under certain conditions by requiring revising the operator's existing Minimum Equipment List (MEL). This AD also requires 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 AD also prohibits the installation of affected parts 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 The Boeing Company Model 777 airplanes. This proposed AD was prompted by a report indicating multiple findings of cracks in the fuselage skin common to the underwing longeron (UWL). This proposed AD would require external or internal (depending on configuration) inspections for any cracking of the left and right side fuselage skin common to the UWL, and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2023-11-08, which applies to all Airbus SAS Model A330-841 and -941 airplanes. AD 2023-11-08 requires maintenance actions, including a high-pressure valve (HPV) seal integrity test, repetitive replacement of the HPV clips, revision of the existing airplane flight manual (AFM), and implementation of updates to the FAA-approved operator's minimum equipment list (MEL). Since the FAA issued AD 2023-11-08, the agency determined that the replacement intervals required by AD 2023- 11-08 must be reduced in order to address the unsafe condition. This proposed AD would continue to require the actions in AD 2023-11-08 and would reduce the HPV clip replacement intervals, and would require, for certain airplanes, an additional revision of the existing AFM. This proposed AD would also limit the installation of HPV clips, 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.

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 the renewal of an information collection. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on January 4, 2024. The collection involves information about requests for waivers from certain operational rules that apply to small unmanned aircraft systems (sUAS). The FAA uses the collected information to make determinations whether to authorize or deny the requested operations of sUAS. The information collected 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 adopting a new airworthiness directive (AD) for certain Pratt & Whitney (PW) Model PW1519G, PW1521G, PW1521GA, PW1521G- 3, PW1524G, PW1524G-3, PW1525G, PW1525G-3, PW1919G, PW1921G, PW1922G, PW1923G, and PW1923G-A engines. This AD was prompted by an updated analysis of an event involving an International Aero Engines, LLC (IAE LLC) Model PW1127GA-JM engine, which experienced a high-pressure compressor (HPC) 7th-stage integrally bladed rotor (IBR-7) separation that resulted in an engine shutdown and aborted takeoff. This AD requires performing an angled ultrasonic inspection (AUSI) of certain high-pressure turbine (HPT) 1st-stage hubs, HPT 2nd-stage hubs, and HPC 8th-stage disks for cracks and, depending on the results of the inspections, replacing the HPT 1st-stage hubs, HPT 2nd-stage hubs, or HPC 8th-stage disks. This AD also requires accelerated replacement of certain HPC 7th-stage rotors, HPC 8th-stage disks, HPC rear hubs, HPT 1st-stage hubs, HPT 2nd-stage hubs, HPT 1st-stage air seals, HPT 2nd- stage air seals, HPT 1st-stage blade retaining plates, and HPT 2nd- stage blade retaining plates. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2022-19-15 for certain International Aero Engines, LLC (IAE LLC) Model PW1100G series engines; and AD 2023-16-07 for certain IAE LLC Model PW1100G series engines and PW1400G series engines. AD 2022-19-15 required an angled ultrasonic inspection (AUSI) of the high-pressure turbine (HPT) 1st-stage disk and HPT 2nd-stage disk, and replacement, if necessary. AD 2023-16-07 required an AUSI of the HPT 1st-stage hub (also known as the HPT 1st-stage disk) and HPT 2nd-stage hub (also known as the HPT 2nd-stage disk) for cracks, and replacement, if necessary, which is terminating action for AD 2022-19-15. This AD was prompted by an investigation that determined an increased risk of powdered metal anomalies for all powdered metal parts in certain powdered metal production campaigns, which are susceptible to failure significantly earlier than previously determined. This AD retains the AUSI requirement for certain HPT 1st-stage and HPT 2nd-stage hubs from AD 2023-16-07. This AD requires performing an AUSI of the HPT 1st-stage hub, HPT 2nd-stage hub, high-pressure compressor (HPC) 7th-stage integrally bladed rotor (IBR-7), and HPC 8th-stage integrally bladed rotor (IBR-8) for cracks, and replacing if necessary. This AD also requires accelerated replacement of the HPC IBR-7, HPC IBR-8, HPC rear hub, HPT 1st-stage hub, and HPT 2nd-stage hub. 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 Embraer S.A. Model EMB-545 and EMB-550 airplanes. This AD was prompted by a report of a hard landing event with substantial damage to the airplane, in which the angle of attack (AOA) limiter was engaged during the final approach phase in unstable air conditions and remained engaged until the airplane touched down on the runway. This AD requires revising the Limitations and Normal Procedures sections of the existing airplane flight manual (AFM) to incorporate new operational airspeed limitations, and flight control limitations and approach procedures when AOA limiter protection is engaged, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is incorporated by reference. This AD also requires inspecting records for instances of AOA limiter engagement during a certain phase of flight and reporting findings to the FAA. The FAA is issuing this AD to address the unsafe condition on these products.

This action proposes to modify the Class E airspace area extending upward from 700 feet or more above the surface of the earth at Yerington Municipal Airport, Yerington, NV. This action would support the airport's transition from visual flight rules (VFR) to instrument flight rules (IFR) operations.

This proposed AD was prompted by a manufacturer evaluation that determined a lower life limit is necessary for certain stages 6-10 compressor rotor spools (stages 6-10 spools) than allowed by the engine shop manual (ESM). This proposed AD would require a one-time inspection of the stages 6-10 spools for previously accomplished blend repairs, a one-time inspection of the blend repairs on the stages 6-10 spools for compliance with the updated allowable limits, and replacement if necessary. The FAA is proposing 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. This collection involves two distinct methods of collecting. The first method of collecting uses the traditional paper/ hardcopy forms which is limited in scope. The second method is more expansive and uses online web-based forms or Application Programming Interface (API) upload functionality. The information can then be shared with a potential employer to aid them in their hiring decision- making process. The information collected can be release to a hiring employer by the pilot. Disclosure of their information is not possible unless the pilot first authorizes the release. The information to be collected will be used to and/or is necessary because before allowing an individual to begin service as a pilot, and air carrier or operator shall receive and evaluate all relevant information pertaining to the individual.

The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 757 airplanes. This proposed AD was prompted by reports of several occurrences of a power transfer unit (PTU) control valve that failed to open when commanded. This proposed AD would require installing new relays and changing certain wire bundles leading to the PTU control valve. 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 International Aero Engines, LLC (IAE LLC) Model PW1122G-JM, PW1124G1-JM, PW1124G-JM, PW1127G1-JM, PW1127G1A-JM, PW1127G1B-JM, PW1127G-JM, PW1127GA-JM, PW1129G-JM, PW1130G-JM, PW1133G-JM, and PW1133GA-JM engines. This proposed AD was prompted by an in-flight shutdown (IFSD) caused by the fracture of a low-pressure compressor (LPC) 1st-stage integrally bladed rotor (IBR-1). This proposed AD would require removal and replacement of affected LPC key washers and affected LPC IBR-1 and installation of inlet guide vane (IGV) spacers. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2022-14-10, which applies 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 2022-14-10 requires repetitive inspections for cracking of the radius of the front spar vertical stringers and the horizontal floor beam on a certain frame (FR), repetitive inspections for cracking of the fastener holes of the front spar vertical stringers on that frame, and repair if necessary. AD 2022-14-10 provides, for certain airplanes, a modification of the center wing box area that terminates the repetitive inspections under certain conditions. Since the FAA issued AD 2022-14-10, an additional airplane model has been identified that is also subject to the unsafe condition. This proposed AD would continue to require the actions in AD 2022-14-10 and would add Model A321-271N airplanes to the applicability, 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.
