This notice announces a meeting of the ARAC.

The FAA is adopting a new airworthiness directive (AD) for certain Diamond Aircraft Industries GmbH (DAI) Model DA 42, DA 42 M-NG, and DA 42 NG airplanes. This AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as dissolved or detached fuel tank hose material entering the main fuel tank chambers, which could result in restricted fuel flow with consequent fuel starvation. This AD requires removing the fuel tank connection hoses from service and inspecting the fuel tank connection hoses for damage and detached rubber material. 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 Pilatus Aircraft Ltd. (Pilatus) Model PC-12/47E airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as a batch of incorrectly sized fuel transfer ejector nozzles that were installed on Model PC-12/47E airplanes during production. This proposed AD would require removing the affected fuel transfer ejectors from service and prohibiting installation of the affected fuel transfer ejectors. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for Airbus Helicopters Model EC120B helicopters. This AD was prompted by a report of corrosion found on the external tail boom skin, under the Very High Frequency (VHF) antenna. This AD requires inspecting the tail boom at the VHF antenna attachments and depending on the results, repairing or modifying the tail boom skin, 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 Leonardo S.p.a. Model AB139 and AW139 helicopters. This AD was prompted by the identification of certain parts needing maintenance actions, including life limits and maintenance tasks. This AD requires incorporating into maintenance records requirements (airworthiness limitations), as specified in a European Aviation Safety Agency (now 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 proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 and -1041 airplanes. This proposed AD was prompted by a report indicating that on the A350 final assembly line (FAL), certain load sensing drive struts (LSDS) and drive struts (DS) were found not adjusted (the nut was not torqued) and not locked. Investigation revealed that the LSDS and DS had been changed as re-work action due to pre-installation damage, but production operations (adjustment and locking) were not done afterwards. This proposed AD would require, for certain airplanes, inspection of the LSDS for correct adjustment and locking, and replacement if necessary, and, for certain other airplanes, replacement of each affected DS with a serviceable part, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. 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 Helicopters Model AS350B, AS350B2, AS350B3, and AS350BA helicopters. This AD was prompted by a report that a modification of the electrical wiring of the hydraulic system was wrongly embodied on certain helicopters, and a wiring non-conformity caused the solenoid of the tail rotor (TR) load compensator to de-energize when the ``HYD'' cut-off switch was activated. This AD requires installing a placard in the cockpit, in full view of the pilots; a functional check of the main rotor (MR) and TR servo actuator solenoids, and corrective actions (modification) if necessary; a modification (unless already done); and, after corrective actions or modification, optional removal of the placard, 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 Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by a report indicating that during maintenance, a fuse pin retaining the main landing gear support structure (MLGSS) was found incorrectly engaged in the trunnion block and improperly secured with the associated retaining pin, due to incorrect installation during assembly. This AD requires inspecting the fuse pins and associated retaining pins of the MLGSS for such discrepancies, and corrective action 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.

The FAA is adopting a new airworthiness directive (AD) for certain De Havilland Aircraft of Canada Limited Model DHC-8-401 and - 402 airplanes. This AD was prompted by reports of a possible hard contact between the #2 top high level sensor (HLS) terminal screw head and the #6 outer wing fuel access panel stiffener flange. This AD requires removing and replacing or reworking the #6 outer wing fuel access panel assembly. 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 Airbus Helicopters Deutschland GmbH (AHD) Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, and EC135T3 helicopters. This AD was prompted by a report of restricted collective lever movement caused by entanglement of the emergency flashlight strap with the cargo hook emergency release lever, causing the emergency flashlight to leave its seat. This AD requires replacing each affected emergency flashlight with a serviceable part, 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 proposes to supersede Airworthiness Directive (AD) 2020-22-01 which applies to all Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. AD 2020-22-01 requires inspecting the affected parts and associated frame bores for discrepancies, applicable corrective actions, and reporting certain information if necessary. Since the FAA issued AD 2020-22-01, a significant number of reports were received of finding corrosion on the affected parts. This proposed AD would retain the requirements of AD 2020-22-01, add recurring inspections, and update the applicable service information. 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 Office of Management and Budget (OMB) approval to renew an information collection. Fractional Ownership is a program that offers increased flexibility in aircraft ownership. Owners purchase shares of an aircraft and agree to share their aircraft with others having an ownership share in that same aircraft. Owners agree to put their aircraft into a ``pool'' of other shared aircraft and to lease their aircraft to another owner in that pool. This collection is necessary to ensure compliance with relevant safety regulations. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on September 21, 2021.

The FAA proposes to supersede Airworthiness Directive (AD) 2021-13-06, which applies to certain Airbus SAS Model A350-941 and - 1041 airplanes. AD 2021-13-06 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2021-13-06, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would continue to require the actions in AD 2021-13-06 and 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. The FAA is proposing this AD to address the unsafe condition on these products.

This notice announces a meeting of the AAAC.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. This proposed AD was prompted by a report of smoke in the aft cabin during a maintenance activity, which an investigation determined was caused by a faulty drain line ribbon heater. This proposed AD would require a general visual inspection of all affected potable water-line ribbon heater installations and corrective actions and other specified actions. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2021-11-15 for certain International Aero Engines AG (IAE) V2500 model turbofan engines. AD 2021-11-15 required performance of an ultrasonic inspection (USI) of the high-pressure turbine (HPT) 1st-stage disk and HPT 2nd- stage disk and, depending on the results of the inspections, replacement of the HPT 1st-stage disk or HPT 2nd-stage disk. Since the FAA issued AD 2021-11-15, the FAA determined the need to clarify the compliance time for inspection of any HPT 1st-stage disk or HPT 2nd- stage disk that is installed on a low-thrust model engine but had been previously operated on a high-thrust model engine. This AD requires performance of a USI of the HPT 1st-stage disk and HPT 2nd-stage disk and, depending on the results of the inspections, replacement of the HPT 1st-stage disk or HPT 2nd-stage disk. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2019-20- 10, 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 2019-20-10 required repetitive rototest inspections of the holes at the door stop fittings for any cracking, and corrective actions if necessary. Since the FAA issued AD 2019-20-10, a clarification of a certain compliance time for the rototest inspection was added. This AD clarifies a certain compliance time and continues to require repetitive rototest inspections of the holes at the door stop fittings for any cracking, and repair 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.

The FAA proposes to adopt a new airworthiness directive (AD) for Viking Air Limited (Viking) (type certificate previously held by Bombardier Inc. and de Havilland, Inc.) Model DHC-3 airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as corrosion, wear, and fatigue- related degradation in aging aircraft. This proposed AD would require establishing a corrosion prevention and control program to identify and correct corrosion and cracking. This proposed AD would also require completing all of the initial tasks identified in the program and reporting corrosion findings to Viking. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2020-20-13 for certain General Electric Company (GE) CF6-80A and CF6-80C model turbofan engines. AD 2020-20-13 required ultrasonic inspection (UI) of high-pressure turbine (HPT) stage 1 and stage 2 disks and replacement of any HPT stage 1 or stage 2 disk that fails the inspection. This AD was prompted by an uncontained failure of an HPT stage 2 disk and the manufacturer's subsequent determination to expand the population of affected HPT disks requiring UI inspection. This AD requires UI of HPT stage 1 and stage 2 disks and replacement of any HPT stage 1 or stage 2 disk that fails the inspection. This AD also expands the applicability to include an additional population of affected HPT stage 1 and 2 disks requiring UI inspection. 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 Viking Air Limited (type certificate previously held by Bombardier Inc. and de Havilland, Inc.) Model DHC-6-1, DHC-6-100, DHC- 6-200, DHC-6-300, and DHC-6-400 airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as loose quadrants on the rudder pedal torque tube and signs of loose rivets or rivet joint wear due to inadequate manufacturing tolerances. This proposed AD would require inspecting the rudder pedal torque tube quadrant for looseness and taking corrective action as necessary. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2020-21-06, which applies to certain Airbus SAS Model A350-941 and - 1041 airplanes. AD 2020-21-06 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2020-21-06, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would revise the applicability by adding airplanes and 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. The FAA is proposing this AD to address the unsafe condition on these products.

This action amends the Class D and Class E airspace at Rochester International Airport, Rochester, MN, and St. Cloud Regional Airport, St. Cloud, MN, and revokes the Class E airspace at Rochester International Airport. This action is the result of biennial airspace reviews. The geographic coordinates of St. Cloud Regional Airport are also being updated to coincide with the FAA's aeronautical database.

This action revokes the Class E airspace at Glass Ranch Airport, Carrizo Spring, TX. This action is the result of the cancellation of the instrument procedures and closure of the airport. The geographic coordinates of the Indio-Faith Airport, Carrizo Spring, TX, are also being updated to coincide with the FAA's aeronautical database.

This action amends the Class D and Class E airspace and revokes Class E airspace at Hammond, LA. This action is the result of an airspace review due to the decommissioning of the Hammond very high frequency (VHF) omnidirectional range (VOR).

The FAA is adopting a new airworthiness directive (AD) for certain Textron Aviation Inc. (type certificate previously held by Raytheon Aircraft Company, Hawker Beechcraft Corporation, and Beechcraft Corporation) (Textron) Model 300, 300LW, B300, and B300C airplanes. This AD was prompted by a report of a timing issue where the yaw servo software can generate a motor position fault when the pilot applies rudder input at the same time the rudder boost system is activated, which disables the rudder boost function and leads to a reduced ability of the flight crew to maintain the safe flight and landing of the airplane or loss of control of the airplane. This AD requires updating the software version of the yaw servo. The FAA is issuing this AD to address the unsafe condition on these products.
