Federal Aviation Administration March 2021 – Federal Register Recent Federal Regulation Documents

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments concerning our intention to request the Office of Management and Budget (OMB) approval of a new generic information collection. As part of a Federal Government-wide effort to streamline the process to seek feedback from the public, FAA is requesting approval of a New Generic Information Collection Request: ``Generic Clearance for Customer Interactions''.

The FAA is adopting a new airworthiness directive (AD) for all Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes. This AD was prompted by a report that electronic circuit breakers (ECBs) were found in a locked state after maintenance, but before flight. This AD requires revising the airplane flight manual (AFM) to incorporate a procedure to check for the ECB status. 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 for a new information collection. The collection involves data and report submissions by State, local and tribal participants in the UAS BEYOND program, and by industry participants in the Partnership for Safety Plan (PSP) program. UAS BEYOND and PSP participants will also conduct qualitative, non- statistical surveys of the general public. The information to be collected will be used to inform FAA policy and decision-making regarding integrating UAS into the National Airspace System.

The FAA proposes to supersede airworthiness directive (AD) 2020-13-07, which applies to all Rolls-Royce Deutschland Ltd & Co KG (RRD) Trent 1000-D2, Trent 1000-J2, and Trent 1000-K2 model turbofan engines with a certain part-numbered fuel pump installed. AD 2020-13-07 requires removal and replacement of the fuel pump with a part eligible for installation. Since the FAA issued AD 2020-13-07, the manufacturer determined that an additional part-numbered fuel pump is subject to the same unsafe condition identified in AD 2020-13-07. This proposed AD would add an additional part-numbered fuel pump and additional Trent 1000 model turbofan engines to the applicability. This proposed AD would require new and reduced life limits, depending on the engine model, for affected fuel pumps. The FAA is proposing this AD to address the unsafe condition on these products.

This action withdraws the final rule published in the Federal Register on August 20, 2020, removing Jet Route J-590, amending VHF Omnidirectional Range (VOR) Federal airways V-11 and V-70, and establishing area navigation (RNAV) routes T-362 and T-365 due to the planned decommissioning of the VOR portion of the Greene County, MS, VOR/Tactical Air Navigation (VORTAC) navigation aid. Unanticipated issues affecting the completion of related VOR Minimum Operational Network (MON) Program instrument procedure amendments and the associated flight inspection activities required to adopt those amendments continue and have made this withdrawal action necessary.

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS332L, AS332L1, AS332C, and AS332C1 helicopters. This AD was prompted by the failure of a second stage planet gear installed in the main gearbox (MGB). This AD requires identifying the part number of each second stage planet gear assembly installed in the MGB, replacing an MGB having certain second stage planet gear assembly part numbers with a serviceable MGB, modifying the helicopter by installing a full flow magnetic plug (FFMP), repetitively inspecting the FFMP and the MGB bottom housing and conical housing for metal particles, analyzing any metal particles that are found, and applying corrective actions if necessary, as specified in European Union Aviation Safety Agency (EASA) ADs, which are 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 Airbus Helicopters Deutschland GmbH Model MBB-BK 117 A-1, MBB-BK 117 A-3, MBB-BK 117 A-4, MBB-BK 117 B-1, MBB-BK 117 B-2, and MBB-BK 117 C-1 helicopters. This proposed AD was prompted by an analysis of the main rotor (M/R) blade loop area. This proposed AD would require repetitive inspections of certain M/R blade thimble areas and corrective actions if necessary, as specified in a European Aviation Safety Agency (now 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.

This amendment adopts miscellaneous amendments to the required IFR (instrument flight rules) altitudes and changeover points for certain Federal airways, jet routes, or direct routes for which a minimum or maximum en route authorized IFR altitude is prescribed. This regulatory action is needed because of changes occurring in the National Airspace System. These changes are designed to provide for the safe and efficient use of the navigable airspace under instrument conditions in the affected areas.

The FAA proposes to supersede Airworthiness Directive (AD) 2019-21-11 and AD 2020-07-02. AD 2019-21-11 applies to all Pratt & Whitney (PW) PW1519G, PW1521G, PW1521G-3, PW1521GA, PW1524G, PW1524G-3, PW1525G, PW1525G-3, PW1919G, PW1921G, PW1922G, PW1923G, and PW1923G-A model turbofan engines. AD 2020-07-02 applies to all PW PW1519G, PW1521G, PW1521G-3, PW1521GA, PW1524G, PW1524G-3, PW1525G, and PW1525G- 3 model turbofan engines. AD 2019-21-11 requires initial and repetitive borescope inspections (BSIs) of the low-pressure compressor (LPC) rotor 1 (R1) and, depending on the results of the inspections, replacement of the LPC. AD 2020-07-02 requires the removal from service of certain electronic engine control (EEC) full authority digital electronic control (FADEC) software and the installation of a software version eligible for installation. Since the FAA issued AD 2019-21-11 and AD 2020-07-02, the manufacturer developed a new version of EEC FADEC software, which terminates the need for repetitive BSIs of the LPC R1. This proposed AD would continue to require repetitive BSIs of certain LPC R1s until replacement of EEC FADEC software with the updated software. This proposed AD would require a BSI after installation of the updated EEC FADEC software if certain Onboard Maintenance Message fault codes are displayed and meet specified criteria. 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 certain Airbus SAS Model A350-941 and -1041 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), which is proposed for incorporation by reference. This proposed AD would also require, for certain airplanes, an update of the hydraulic monitoring system to include additional redundancy. 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 type certificated Model UH-1H restricted category helicopters. This proposed AD was prompted by multiple reports of failure of the main driveshaft. This proposed AD would require establishing a life limit for certain main driveshafts, and a one-time and repetitive inspections of the main driveshafts. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) AD 2019- 12-09 for certain Rockwell Collins, Inc. (Rockwell Collins) FDSA-6500 flight display system applications installed on airplanes. AD 2019-12- 09 imposed operating limitations on the traffic collision avoidance system (TCAS). AD 2019-12-09 was prompted by conflict between the TCAS display indications and aural alerts that may occur during a resolution advisory (RA) scenario. This AD retains the requirements of AD 2019-12- 09 until a software upgrade is completed. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2019-06-06 for all International Aero Engines AG (IAE) V2500-A1, V2522-A5, V2524- A5, V2525-D5, V2527-A5, V2527E-A5, V2527M-A5, V2528-D5, V2530-A5, and V2533-A5 model turbofan engines. AD 2019-06-06 required initial and repetitive borescope inspections (BSIs) of the M-flange and, if it fails the inspection, replacement of the diffuser case with a part eligible for installation. This AD requires an initial BSI of the M- flange and, if it fails the inspection, repetitive BSIs of the M-flange until replacement of the diffuser case M-flange. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2007-26-52 which applied to certain Agusta S.p.A. (now Leonardo) Model A109C, A109E, and A109K2 helicopters. AD 2007-26-52 required inspecting for swelling, deformation, bonding separation, and for a crack on each main rotor blade (MRB) with a certain part-numbered tip cap installed, and removing the MRB from service before further flight if any of these conditions exist and exceed the prescribed limits. This AD retains all inspections for certain serial-numbered MRBs, but for MRBs with a certain tip cap installed, this AD requires dye-penetrant inspections rather than visual inspections. This AD was prompted by additional reports of in-flight loss of part of a tip cap. The FAA is issuing this AD to address the unsafe condition on these products.

This rule establishes, amends, suspends, or removes Standard Instrument Approach Procedures (SIAPS) and associated Takeoff Minimums and Obstacle Departure procedures (ODPs) 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 safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 747 series airplanes and Model 767 series airplanes. This AD was prompted by a report of an un-commanded fuel transfer between the main and center fuel tanks. This AD prohibits operation of an airplane with any inoperative refuel valve (fueling shut-off valve) failed in the open position. The FAA is issuing this AD to address the unsafe condition on these products.

This action proposes to amend the Class D and Class E airspace at Sioux Gateway Airport/Brigadier General Bud Day Field, Sioux City, IA. The FAA is proposing this action as the result of an airspace review caused by the decommissioning of the Sioux City VHF omnidirectional range (VOR) navigation aid as part of the VOR Minimum Operational Network (MON) Program. The name and geographic coordinates of the airport would also be updated to coincide with the FAA's aeronautical database.

This action revokes the Class E airspace established for Bedard Field Airport, Kayenta, AZ. The special instrument procedures that were developed for the private airport have been canceled. The Class E airspace is no longer required.

This action modifies the Class E airspace extending upward from 700 feet above the surface at Central Colorado Regional Airport, Buena Vista, CO. This action modifies the airspace to properly contain instrument flight rules (IFR) aircraft departing and arriving at the airport. Additionally, this action removes the Class E airspace extending upward from 1,200 feet above the surface. This airspace is wholly contained within the Denver en route airspace area and duplication is not necessary. Lastly, this action implements an administrative update to the airport's name.

The FAA proposes to supersede Airworthiness Directive (AD) 79- 01-03, which applies to certain Piper Aircraft, Inc. (Piper) Model PA- 36-285 airplanes, and AD 83-20-03, which applies to Piper Models PA-36- 285, PA-36-300, and PA-36-375 airplanes. AD 79-01-03 requires repetitive inspections of the spar carry through assembly until it is replaced with a different part numbered spar carry through assembly. AD 83-20-03 establishes life limits for the wing spar structural components. Since the FAA issued AD 79-01-03 and AD 83-20-03, the FAA identified inspection and life limit requirements that were inadvertently omitted from those ADs. This proposed AD would retain the requirements in AD 79-01-03 and AD 83-20-03 and require the spar carry through assembly inspection from AD 79-01-03 for additional airplanes and add life limits for certain wing structural components previously omitted from AD 83-20-03 for certain serial numbered airplanes. 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 Canada Limited Partnership Model BD-500-1A10 and BD-500- 1A11 airplanes. This AD was prompted by a report that threaded fuel couplings were incorrectly installed at final assembly and in service. This AD requires repetitive functional tests of the auxiliary power unit (APU) fuel feed line shroud, a general visual inspection of the APU fuel feed line shroud for any loose couplings; and tightening any loose couplings, which would terminate the repetitive functional tests. 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 Bell Textron Canada Limited (type certificate previously held by Bell Helicopter Textron Canada Limited) (Bell) Model 505 helicopters. This proposed AD was prompted by the discovery of a gap between the transmission restraint assembly aft attachment hardware lower washer and mating airframe truss assembly (truss assembly) clevis lower lug. This proposed AD would require inspecting the transmission restraint aft attachment hardware installation for a gap and corrective action depending on the inspection results. 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 Airbus SAS Model A330-200, A330-200 Freighter, A330-300, A340- 200, and A340-300 series airplanes. This proposed AD was prompted by a report that the auxiliary power unit (APU) aft fuel pump printed circuit board (PCB) varnish had deteriorated; the varnish is one of the layers of protection against development of an ignition source. This proposed AD would require replacing each affected APU aft fuel pump, 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 proposes to adopt a new airworthiness directive (AD) for certain De Havilland Aircraft of Canada Limited Model DHC-8-400 series airplanes. This proposed AD was prompted by a report that a number of nacelle A-frames were not manufactured in accordance with engineering drawings. This proposed AD would require, depending on airplane configuration, removing the fasteners on the nacelle A-frame side brace sub-assemblies, doing an eddy current inspection for cracking, cold-working the holes, installing oversize fasteners, re- identifying the reworked side brace fitting and A-frame, and repair if necessary. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is issuing this notice under the provisions of the National Environmental Policy Act (NEPA) of 1969, as amended, to announce the availability of the Final Environmental Impact Statement (EIS) for the proposed LaGuardia Airport (LGA) Access Improvement Project and its connected actions (the Proposed Action). The Proposed Action would provide direct access between LGA and the Metropolitan Transportation Authority (MTA) Long Island Rail Road (LIRR) Mets- Willets Point Station and the New York City Transit (NYCT) 7 Line Mets- Willets Point Station. FAA is the lead federal agency in the preparation of the EIS, with cooperating agencies including National Park Service (U.S. Department of the Interior); U.S. Army Corps of Engineers; U.S. Environmental Protection Agency; New York State Department of Environmental Conservation; New York State Department of Transportation; and New York State Office of Parks, Recreation and Historic Preservation. The Final EIS was prepared to disclose the potential environmental impacts resulting from the Proposed Action, including real property transactions under the New York State Eminent Domain Procedures Law.
