Federal Aviation Administration June 2020 – Federal Register Recent Federal Regulation Documents

The FAA proposes to supersede Airworthiness Directive (AD) 2017-25-04, 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, 231, 232, and 233 airplanes; and Model A321 111, 112, 131, 211, 212, 213, 231, and 232 airplanes. The FAA also proposes to supersede AD 2019-03-17, 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, -233, -251N, and -271N airplanes; and Model A321 series airplanes. AD 2019-03-17 requires revising the existing maintenance or inspection program, as applicable, to incorporate new maintenance requirements and airworthiness limitations. Since the FAA issued AD 2019-03-17, the FAA has determined 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) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is superseding airworthiness directive (AD) 2011-20-01 for certain Empresa Brasileira de Aeron[aacute]utica S.A. (now Embraer S.A.) Model EMB-505 airplanes. AD 2011-20-01 required replacing the bolts that attach the balance mass weights to the elevator structure. This AD requires inspections of the mass-balance weights of the elevators, ailerons, and rudder (flight control surfaces) and their attachment parts and corrective actions if necessary, and revising the airworthiness limitation section of the existing maintenance manual or instructions for continued airworthiness to incorporate new airworthiness limitations. This AD also adds airplanes to the applicability. This AD was prompted by reports of corrosion in the mass-balance weights of the flight control surfaces, and a determination that new airworthiness limitations are necessary. 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 Bombardier, Inc., Model BD-100-1A10 airplanes. This AD was prompted by reports of the loss of all air data system information provided to the flightcrew, which was caused by icing at high altitudes. This AD requires revising the existing airplane flight manual (AFM) to provide the flightcrew with procedures to stabilize the airplane's airspeed and attitude. The FAA is issuing this AD to address the unsafe condition on these products.

This action proposes special conditions for the Bombardier Inc. (Bombardier) Model CL-600-2B19 airplane. This airplane, as modified by Aerospace Design and Compliance, LLC (Aerospace Design and Compliance), will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The design feature is an installation of a therapeutic oxygen system for medical use. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed 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.

The FAA is adopting a new airworthiness directive (AD) for certain Hamilton Sundstrand Corporation (Hamilton Sundstrand) 54H60 model propellers. This AD was prompted by the failure of a propeller blade that resulted in the loss of the airplane. This AD requires initial and repetitive eddy current inspections (ECIs) of the affected propeller blades and replacement of the propeller blades that fail the inspection. The FAA is issuing this AD to address the unsafe condition on these products.

This action proposes to establish area navigation (RNAV) routes T-301 and T-305 in the northcentral United States. The proposed new RNAV routes would expand the availability of RNAV routing in support of transitioning the National Airspace System (NAS) from ground-based to satellite-based navigation. Additionally, a portion of the new RNAV routes would provide enroute structure where VHF Omnidirectional Range (VOR) Federal airway segments were removed due to the Cape Girardeau, MO, VOR being decommissioned in support of the FAA's VOR Minimum Operational Network (MON) program.

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.

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.

This action proposes to remove two Colored Federal airways, A- 7 and G-11, and amend one Colored Federal airway, A-1 in Alaska. The modifications are necessary due to the planned decommissioning of to the Campbell Lake Non-Directional Beacon (NDB) in Anchorage, AK, which provides navigation guidance for portions of the affected routes. The Campbell Lake NDB is to be decommissioned effective November 5, 2020 due to ongoing maintenance problems.

The FAA proposes to adopt a new airworthiness directive (AD) for all Pratt & Whitney Division (PW) PW4164, PW4164-1D, PW4168, PW4168-1D, PW4168A, PW4168A-1D, and PW4170 model turbofan engines with a certain outer combustion chamber assembly and 3rd stage low-pressure turbine (LPT) duct segments installed. This proposed AD was prompted by reports of damaged or failed 3rd stage LPT duct segments on PW engines with the Talon IIB outer combustion chamber assembly configuration installed. This proposed AD would require removing and replacing certain 3rd stage LPT duct segments. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2011-12-08 for Bell Helicopter Textron Inc. (Bell), Model 205A, 205A-1, 205B, 212, 412, 412CF, and 412EP helicopters. AD 2011-12-08 required a one-time inspection of the tail rotor (T/R) blade for corrosion and pitting. This new AD retains the requirements of AD 2011-12-08 while excluding certain T/R blades from the applicability. This AD was prompted by new manufacturing and inspection procedures implemented by Bell that correct the unsafe condition on more recently manufactured T/R blades. The actions of this AD are intended to address an unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2018-26-02 for Airbus Helicopters (previously Eurocopter France) Model AS350B3, EC130B4, and EC130T2 helicopters. AD 2018-26-02 requires inspecting the pilot's and co-pilot's throttle twist for proper operation. Since the FAA issued AD 2018-26-02, the FAA received a public comment that prompted additional review. This proposed AD would retain the requirements of AD 2018-26-02 and add calendar time compliance times for the required actions. The actions of this proposed AD are intended to address an unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2010-23- 04, which applied to all De Havilland Aircraft of Canada Limited Model DHC-8-400 series airplanes. AD 2010-23-04 required repetitive detailed inspections of the nacelle attachment fittings for cracks, a conductivity inspection of the nacelle attachment fittings, and replacement if necessary. This AD continues to require these inspections and replacement if necessary, removes a certain inspection requirement for certain airplanes, and adds a new requirement to replace the rear spar fitting and nacelle attaching structure with a new nacelle attachment fitting. This AD was prompted by a determination that it is necessary to do a replacement with new nacelle attachment fittings. 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 Inc. (Type Certificate previously held by Bell Helicopter Textron Inc.) (Bell), Model 204B, 205A-1, and 212 helicopters. This proposed AD was prompted by reports of corrosion on main rotor hub tension-torsion strap (TT strap) assemblies. This proposed AD would require reducing the life limit of a certain part- numbered TT strap assembly and prohibit installing this TT strap assembly on any helicopter. The FAA is proposing this AD to address the unsafe condition on these products.

This action proposes to modify the Class D and Class E surface area at Bethel Airport, Bethel AK, by redefining the Hangar Lake exclusion area and eliminating the use of the VORTAC in the descriptions. This action also proposes to remove Class E airspace as an extension to the Class D and Class E surface area and modify the Class E airspace extending upward from 700 feet above the surface at the Airport. After a biennial review of the airspace, the FAA found it necessary to amend the existing airspace for the safety and management of Instrument Flight Rules (IFR) operations at this airport. This action would also update the geographical coordinates and make a minor editorial change replacing the outdated term Airport/Facility Directory with the term Chart Supplement.

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model EC120B helicopters. This AD was prompted by a report that a changed manufacturing process for the tail rotor blades (TRB) was implemented, affecting the structural characteristics of the blades and generating a new part number for these blades. This AD requires re-identifying each affected TRB having a certain part number and serial number and establishing a life limit for the new part numbers. This AD also prohibits installation of any affected TRB identified with the old part number on any helicopter. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2017-18-17, which applies to all Airbus SAS Model A300 B4-603, A300 B4- 620, A300 B4-622, A300 B4-605R, A300 B4-622R, A300 F4-605R, A300 F4- 622R, and A300 C4-605R Variant F airplanes. AD 2017-18-17 requires modifying certain fuselage frames and a repair on certain modified airplanes. Since AD 2017-18-17 was issued, the FAA has determined that, for certain airplanes, a rotating probe inspection must be performed prior to oversizing of the open-holes, and consequently more work is necessary for airplanes that have previously been modified. This proposed AD would continue to require the actions in AD 2017-18-17. This proposed AD would also require, for certain airplanes, an inspection to determine if rotating probe inspections were performed prior to oversizing of the open-holes, and repair if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2018-15-04, which applies to certain General Electric Company (GE) CF6- 80A, CF6-80A1, CF6-80A2, CF6-80A3, CF6-80C2A1, CF6-80C2A2, CF6-80C2A3, CF6-80C2A5, CF6-80C2A5F, CF6-80C2A8, CF6-80C2B1, CF6-80C2B1F, CF6- 80C2B2, CF6-80C2B2F, CF6-80C2B4, CF6-80C2B4F, CF6-80C2B5F, CF6-80C2B6, CF6-80C2B6F, CF6-80C2B6FA, CF6-80C2B7F, CF6-80C2D1F, CF6-80C2L1F, and CF6-80C2K1F model turbofan engines. AD 2018-15-04 requires ultrasonic inspection (UI) of high-pressure turbine (HPT) stage 1 and stage 2 disks. Since we issued AD 2018-15-04, GE determined the need to expand the population of affected disks. This proposed AD would retain the required inspections while expanding the population of affected disks. The FAA is proposing this AD to address the unsafe condition on these products.

The Federal Aviation Administration (FAA) is considering a proposal and invites public comment to change a portion of the airport from aeronautical use to non-aeronautical use at Salinas Municipal Airport (SNS), Salinas, Monterey County, California. The proposal consists of one parcel containing 13.25 acres of airport land, located outside of the airfield, south of Airport Boulevard, between Mercer Way and Skyway Boulevard, and north of Mortensen Avenue.

This action amends the Class D airspace at Fort Worth Spinks Airport, Fort Worth, TX, and the Class E airspace extending upward from 700 feet above the surface at Bourland Field, Fort Worth, TX, and Mesquite Metro Airport, Mesquite, TX, and Stephenville Clark Regional Airport, Stephenville, TX. These actions are the result of airspace reviews caused by the decommissioning of the Glen Rose VHF omnidirectional range (VOR) navigation aid as part of the VOR Minimum Operational Network (MON) Program. The geographic coordinates and names of several airports are also being updated to coincide with the FAA's aeronautical database.

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. The collection aids to make the aircraft noise certification information easily accessible to the flight crew and presentable upon request to the appropriate foreign officials for international airline operation of U.S. carriers. The information to be collected upholds the U.S. obligations under the Convention on International Civil Aviation and for which FAA policy comply with International Civil Aviation Organization (ICAO) Standards and Recommended Practices to the maximum extent practicable. Thus the FAA has adopted ICAO's Standards and Recommended Practices as US regulations as a means of compliance with Annex 16 and requires noise documentation be carried on board aircraft that leave the United States.

These special conditions are issued for the Leonardo Model AW169 helicopter. This model helicopter will have the novel or unusual design feature associated with a 30-minute all engines operating (AEO) power rating. 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.

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. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on March 31, 2020. The reporting and recordkeeping requirements of this collection are related to FAA rules governing the operation of aircraft (other than moored balloons, kites, rockets, unmanned free balloons, and small unmanned aircraft) within the United States. These reporting and recordkeeping requirements are necessary for the FAA to assure compliance with these provisions.
