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.
Airworthiness Directives; General Electric Company Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) CF34-8C and CF34-8E model turbofan engines. This AD was prompted by an in-flight shutdown of an engine and subsequent investigation by the manufacturer that revealed a broken variable geometry (VG) actuator rod end caused by corrosion and seizure of the rod end bearing. This AD requires performing an inspection of the master compressor VG actuator and slave compressor VG actuator and, depending on the results of the inspection, replacement of the part with a part eligible for installation. This AD also requires reporting the results of the inspection to GE. The FAA previously sent an emergency AD to all known U.S. owners and operators of these GE CF34-8C and CF34-8E model turbofan engines and is now issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bell Textron Canada Limited Helicopters
The FAA is adopting a new airworthiness directive (AD) for Bell Textron Canada Limited Model 206L-1, 206L-3, and 206L-4 helicopters with certain Air Comm Corporation air conditioning systems installed. This AD was prompted by reports of damage to the drive ring spline teeth and the mating spline teeth. This AD requires visually inspecting the drive ring spline teeth and the mating area spline teeth on the oil cooler blower shaft for signs of deformation and fretting and depending on the results of the inspection, removing certain parts from service. This AD also requires reinstalling certain parts, applying torque, and aligning certain bolt holes. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Diamond Aircraft Industries GmbH Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Diamond Aircraft Industries GmbH (DAI) Model DA 42, DA 42 NG, and DA 42 M-NG airplanes. This proposed 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 a loose rudder T-yoke axle nut. This proposed AD would require replacing the rudder T-yoke axle with an improved rudder T-yoke axle. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters Deutschland GmbH Helicopters
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, and EC135T3 helicopters. This AD was prompted by reduced life limits being established for certain part-numbered tail rotor (TR) blades. This AD requires determining the total hours time-in-service (TIS) of certain part- numbered TR blades, establishing a life limit for certain part-numbered TR blades, removing from service any TR blade that has reached or exceeded its life limit, creating a component history card, re- identifying certain part-numbered TR blades, and removing any TR blade from service before reaching its retirement life. This AD also prohibits installing certain TR blades on certain model helicopters. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Leonardo S.p.a. Helicopters
The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. Model AB139 and AW139 helicopters. This AD was prompted by reports of failed main rotor (MR) dampers. This AD requires various inspections of certain MR dampers, 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.
Airworthiness Directives; Daher Aerospace (Type Certificate Previously Held by SOCATA) Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Daher Aerospace (type certificate previously held by SOCATA) Model TB 20 and TB 21 airplanes. This AD was prompted by 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 cracks on the main landing gear (MLG) legs. This AD requires repetitively inspecting the MLG and performing all applicable corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
Proposed Amendment of Class C Airspace at Nashville International Airport, TN; Informal Airspace Meeting
This notice announces a fact-finding informal airspace meeting regarding a plan to modify the Class C Airspace at Nashville International Airport, TN (KBNA). The meeting will be a virtual format via the Zoom platform. The purpose of the meeting is to solicit aeronautical comments on the proposal's effects on local aviation operations. All comments received during the meeting, and the subsequent comment period, will be considered prior to the issuance of a notice of proposed rulemaking.
Proposed Amendment and Removal of VOR Federal Airways V-18, V-115, V-222, V-241, V-245, V-311, V-321, V-325, V-333, V-415, V-417, and V-463 in the Southeastern United States
This action proposes to modify 7 VHF Omnidirectional Range (VOR) Federal Airways, (V-18, V-115, V-222, V-241, V-245, V-321, and V- 333) and remove 5 VOR Federal Airways, (V-311, V-325, V-415, V-417, and V-463) in association with the Atlanta VOR Minimum Operation Network (MON) project in the southeastern United States. This action is necessary due to the planned decommissioning of the following five ground-based navigational aids (NAVAIDs): Dyersburg, TN, (DYR) VOR and Tactical Air Navigational System (VORTAC); Crimson, AL, (LDK) VORTAC; Malden, MO, (MAW) VORTAC; Monticello, AR, (MON) VOR/DME; and the Muscle Shoals, AL, (MSL) VOR/Distance Measuring Equipment (DME). This proposal would provide for the safe and efficient use of navigable airspace within the National Airspace System (NAS) while reducing NAVAID dependencies throughout the NAS as part of the FAA VOR MON program.
Proposed Amendment of VOR Federal Airways V-7, V-9, and V-11; Eastern United States
This action proposes to modify VHF Omnidirectional Range (VOR) Federal airways V-7, V-9, and V-11. This action is necessary due to the planned decommissioning of the Dyersburg, TN, (DYR); Malden, MO, (MAW); and the Muscle Shoals, AL, (MSL), VOR and Tactical Air Navigation (VORTAC) facilities, under the FAA's VOR Minimum Operational Network (MON) program, which provide navigation guidance for segments of the routes.
