Federal Aviation Administration January 2022 – Federal Register Recent Federal Regulation Documents

This notice contains a summary of a petition seeking relief from specified requirements of Federal Aviation Regulations. The purpose of this notice is to improve the public's awareness of, and participation in, the FAA's exemption process. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of the petition or its final disposition.

The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This AD was prompted by a determination that radio altimeters cannot be relied upon to perform their intended function if they experience interference from wireless broadband operations in the 3.7-3.98 GHz frequency band (5G C-Band), and a recent determination that, during landings, as a result of this interference, certain airplane systems may not properly transition from AIR to GROUND mode when landing on certain runways, resulting in degraded deceleration performance and longer landing distance than normal due to the effect on thrust reverser deployment, speedbrake deployment, and increased idle thrust. This AD requires revising the limitations and operating procedures sections of the existing airplane flight manual (AFM) to incorporate limitations prohibiting certain landings and the use of certain minimum equipment list (MEL) items, and to incorporate operating procedures for calculating landing distances, when in the presence of 5G C-Band interference as identified by Notices to Air Missions (NOTAMs). The FAA is issuing this AD to address the unsafe condition on these products.

These special conditions are issued for the Bell Textron Inc. (Bell) Model 525 helicopter. This helicopter will have a novel or unusual design feature associated with a fly-by-wire (FBW) flight control system (FCS). The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

This action amends Class D airspace, Class E surface area, and Class E airspace extending upward from 700 feet above the surface for Columbus Airport and Lawson Army Air Field (AAF) (Fort Benning), Columbus, GA. This action merges Columbus Airport and Lawson AAF (Fort Benning) Class D airspace and Class E surface area airspace into one header under FAA Order JO 7400.11 and removes the header Columbus Lawson AAF under FAA Order JO 7400.11. This action also amends Columbus Airport's Class D by updating the name of Columbus Airport, (formerly Columbus Metropolitan Airport) and updating the name of Lawson Army Airfield (Fort Benning), (formerly Columbus Lawson AAF); the Lawson AAF (Fort Benning) Class D is amended by establishing an extension to the southeast. This action establishes Class E airspace designated as an extension to a Class D surface area for Columbus Airport, Columbus, GA. The Columbus Airport Class E surface area extension is eliminated and Lawson AAF (Fort Benning) Class E surface area is amended by establishing an extension to the southeast. Columbus Class E airspace extending upward from 700 feet above the surface and Lawson AAF (Fort Benning) Class E airspace extending upward from 700 feet above the surface is amended by increasing the radii and removing the Lawson Very High Frequency Omnidirectional Range with Distance Measuring Equipment (VOR/DME) and Lawson Localizer (LOC) from the description. In addition, this action also makes an editorial change replacing the term Airport/ Facility Directory with the term Chart Supplement in the legal descriptions of associated Class D airspace and Class E surface area. In addition, this action updates the geographic coordinates of the Lawson AAF (Fort Benning) to coincide with the FAA's database. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.

The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-400, -400D, and -400F series airplanes. This AD was prompted by reports of burned Boeing Material Specification (BMS) 8-39 urethane foam, and a report from the airplane manufacturer that airplanes were assembled with seals throughout various areas of the airplane (including flight deck and cargo compartments) made of BMS 8-39 urethane foam, a material with fire- retardant properties that deteriorate with age. This AD requires replacing the system tube/wire seals made of BMS 8-39 urethane foam in certain areas of the airplane. The FAA is issuing this AD to address the unsafe condition on these products.

This action amends the Class E airspace at Bonham, TX. This action is the result of an airspace review due to the decommissioning of the Bonham non-directional beacon (NDB). The geographic coordinates of the airport are also being updated to coincide with the FAA's aeronautical database.

This action proposes to amend the Class E airspace at Watonga, OK. The FAA is proposing this action due to an airspace review conducted as part of the decommissioning of the Kingfisher very high frequency (VHF) omnidirectional range (VOR) as part of the VOR Minimal Operational Network (MON) Program. The name and geographic coordinates of the airport would also be updated to coincide with the FAA's aeronautical database.

The FAA proposes to adopt a new airworthiness directive (AD) for all CFM International, S.A. (CFM) LEAP-1A23, LEAP-1A24, LEAP- 1A24E1, LEAP-1A26, LEAP-1A26CJ, LEAP-1A26E1, LEAP-1A29, LEAP-1A29CJ, LEAP-1A30, LEAP-1A32, LEAP-1A33, LEAP-1A33B2, and LEAP-1A35A model turbofan engines. This proposed AD was prompted by the detection of melt-related freckles in the billet, which may reduce the life of certain compressor rotor stages 6-10 spools, high pressure turbine (HPT) rotor interstage seals, HPT rotor stage 2 disks, low pressure turbine (LPT) stage 1 disks, LPT stage 2 disks, LPT stage 3 disks, and LPT stage 4 disks. This proposed AD would require revising the airworthiness limitations section (ALS) of the applicable CFM LEAP-1A Engine Shop Manual (ESM) and the operator's existing approved continuous airworthiness maintenance program (CAMP) to incorporate reduced life limits for these parts. This proposed AD would also require the removal of certain LPT stage 4 disks identified by serial number (S/N) prior to their new life limits. The FAA is proposing this AD to address the unsafe condition on these products.

This action proposes to amend United States Area Navigation (RNAV) route T-232 in the vicinity of Fairbanks, AK in support of a large and comprehensive T-route modernization project for the state of Alaska.

The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.a. Model AW169 helicopters. This AD was prompted by a report of a broken adjustable device that is part of the pilot and co- pilot yaw pedal assemblies. This AD requires modification of certain pilot and co-pilot yaw pedal assemblies with an improved design and re- identification of affected parts, 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.

This action proposes to amend Class E airspace extending upward from 700 feet above the surface at Claremont Airport, Elkton, MD, as an airspace review found the airspace radius required an increase, as well as updating the airport's name. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.

This action amends Jet Route J-181 and VHF Omnidirectional Range (VOR) Federal airways V-13, V-14, V-15, and V-307; establishes Area Navigation (RNAV) routes T-411 and T-413; and removes VOR Federal airway V-506. The FAA is taking this action due to the planned decommissioning of the VOR portion of the Neosho, MO, VOR/Distance Measuring Equipment (VOR/DME) navigational aid (NAVAID). The Neosho VOR is being decommissioned in support of the FAA's VOR Minimum Operational Network (MON) program.

This action proposes to establish United States Area Navigation (RNAV) route T-370 in the vicinity of Kenai, AK in support of a large and comprehensive T-route modernization project for the state of Alaska.

This action proposes to modify the Class E airspace extending upward from 700 feet above the surface at Rifle Garfield County Airport, Rifle, CO. This action would ensure the safety and management of instrument flight rules (IFR) operations at the airport.

This action amends VHF Omnidirectional Range (VOR) Federal airways V-37 and V-270, and removes VOR Federal airway V-43, in the vicinity of Erie, Pennsylvania. The airway amendments are necessary due to the planned decommissioning of the VOR portion of the Erie, PA, VOR/ Tactical Air Navigation (VORTAC), which provides navigational guidance for these airways. The Erie VOR is being decommissioned as part of the FAA's VOR Minimum Operational Network (MON) program.

This action modifies the Class D airspace at China Lake NAWS (Armitage Field) Airport, China Lake, CA. This action also modifies the Class E airspace extending upward from 700 feet above the surface. Additionally, this action removes the China Lake (Navy) TACAN from the Class E5 text header and airspace description. Lastly, this action implements numerous administrative updates to the Class D and Class E5 text headers and the Class D airspace description. This action ensures the safety and management of instrument flight rule (IFR) operations at the airport.

The FAA proposes to supersede Airworthiness Directive (AD) 2020-20-06, which applies to certain Bell Helicopter Textron Canada Limited (now Bell Textron Canada Limited) Model 429 helicopters. AD 2020-20-06 requires repetitive inspections of certain cyclic and collective assembly bearings. Since the FAA issued AD 2020-20-06, the collective and cyclic bellcrank assemblies have been upgraded with corrosion resistant steel bearings. This proposed AD would retain some of the requirements of AD 2020-20-06 and depending on the inspection results, would require removing certain parts from service and installing the upgraded cyclic and collective bellcrank assemblies. This proposed AD would also require installing the upgraded collective and cyclic bellcrank assemblies on certain helicopters if not already installed, and would prohibit installing certain bellcrank assemblies. The FAA is proposing this AD to address the unsafe condition on these products.

This action amends Class E airspace extending upward from 700 feet above the surface for Covington Municipal Airport, Covington, GA. This action is the result of an airspace review caused by the decommissioning of the ALCOVY Non-directional Beacon (NDB) and cancellation of the associated approaches. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.

This action proposes to establish United States Area Navigation (RNAV) route T-367 in the vicinity of St. Mary's, AK in support of a large and comprehensive T-route modernization project for the state of Alaska.

This action proposes to establish Class E airspace extending upward from 700 feet above the surface to accommodate Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures (SIAPs) serving Iuka Airport, Iuka, MS. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.

The FAA is adopting a new airworthiness directive (AD) for certain Stemme AG Model Stemme S 10-VT and Stemme S 12 gliders. This 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 unintended slipping of the freewheel clutch with overheating (burnishing) of the friction pads inside of the clutch. This AD requires removing the affected freewheel clutch from service. 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 A300 series airplanes Model 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 reports of cracking in the main landing gear (MLG) support rib 5 lower flange. This proposed AD would require a one-time detailed inspection (DET) of the affected area, and applicable corrective actions, 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 superseding Airworthiness Directive (AD) 2021-15- 51, which applied to Bell Textron Inc. (type certificate previously held by Bell Helicopter Textron Inc.) Model 204B, 205A, 205A-1, 205B, and 212 helicopters. AD 2021-15-51 required removing certain main rotor hub strap pins (pins) from service and prohibited installing them on any helicopter. Since the FAA issued AD 2021-15-51, it was determined that a defective pin could also be installed on Bell Textron Inc. Model 210 helicopters. This AD continues the required actions in AD 2021-15- 51 and expands the applicability to add Model 210 helicopters. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2018-25- 16, which applied to certain Airbus Defense and Space S.A. Model CN- 235, CN-235-200, and CN-235-300 airplanes. AD 2018-25-16 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2018-25-16, the FAA has determined that additional new or more restrictive airworthiness limitations, including inspections for discrepancies (cracking) of certain structural elements, are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate additional new or more restrictive airworthiness limitations, and repetitive inspections for discrepancies (cracking) of certain structural elements and 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 certain km, Vulcanair S.p.A. Model P.68C, P.68C-TC, P.68 ``OBSERVER,'' P.68 OBSERVER 2, P.68R, and P.68TC OBSERVER 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 identifies the unsafe condition as a damaged stabilator trim control cable. This AD requires inspecting the stabilator trim control cables and replacing if necessary. This AD also requires reporting the results of each inspection to Vulcanair S.p.A. The FAA is issuing this AD to address the unsafe condition on these products.
