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

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS 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 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) 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 all Austro Engine GmbH E4 and E4P model diesel piston engines. This AD was prompted by a report of oil pressure loss on an E4 model diesel piston engine. This AD requires removing a certain oil pump from service and replacing it with a part eligible for installation. The FAA is issuing this AD to address the unsafe condition on these products.

This action proposes to remove Class E airspace in Concord, NH, as Class E surface airspace is no longer required at Concord Municipal Airport. This action would also amend the Class E airspace extending upward from 700 feet above the surface and update the geographic coordinates of the airport. This action would enhance the safety and management of controlled airspace within the national airspace system.

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 Airbus SAS Model A330-200, -300, -800, and -900 series airplanes; and Model A340-200, -300, -500, and -600 series airplanes. This AD was prompted by reports that certain oxygen supply solenoid valves are a potential source of increased flow resistance within the flightcrew oxygen system. This AD requires a special detailed inspection (flow test) of certain solenoid valves, and replacement 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 all Airbus SAS Model A330-841 and -941 airplanes. This AD was prompted by reports of missing or disbonded pressure seals on two thrust reverser (TR) translating cowls. This AD requires a one-time inspection of each thrust reverser for damage, seal bonding rework, and replacement of translating cowl pressure seals 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 all Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by a report that during an inspection of the flight deck escape hatches it was found that they were difficult to open from the inside, and several hatches were found impossible to open from the outside. Subsequent investigation revealed corrosion on the flight deck escape hatch mechanism due to condensation penetrating inside the mechanism. This AD requires replacing all affected flight deck escape hatches with serviceable hatches, 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 issue a new AD to supersede emergency Airworthiness Directive (AD) 2018-23-52, which applies to all Leonardo S.p.a. Model AW169 and AW189 helicopters. AD 2018-23-52 requires inspecting the nut, cotter pin, lock-wire, and hinge bracket connected to the tail rotor servo-actuator (TRA) feedback lever link, and each connection of the TRA feedback lever link, and repair if necessary. AD 2018-23-52 also requires applying a paint stripe or torque seal on the nut and reporting certain information. Since the FAA issued AD 2018-23- 52, the FAA has determined certain inspections and checks of the tail rotor duplex bearings (TR DB), installation of an improved TRA and TR DB, certain other actions, and applicable corrective actions are necessary to address the unsafe condition. This proposed AD would require repetitive inspections of the TRA, repetitive inspections and checks of the TR DB, installation of an improved TRA and TR DB, repetitive installations and checks of thermal strips, replacement of improved TR DB (life limit), and applicable corrective actions, as specified in a 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 notice corrects the Notice of Availability (NOA) for the Record of Decision for the Final Environmental Impact Statement (EIS) for the proposed LaGuardia Airport (LGA) Access Improvement Project. The original NOA was published in the Federal Register on July 23, 2021 and included an incorrect statement.

The FAA proposes to adopt a new airworthiness directive (AD) for all Diamond Aircraft Industries GmbH Models DA 42, DA 42 NG, and DA 42 M-NG airplanes. This proposed 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 failure of the nose landing gear (NLG) actuator attachment lever and detachment from the NLG leg. This proposed AD would require repetitively inspecting the NLG actuator attachment lever for cracks and damage and taking any necessary corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.

This action amends Area Navigation (RNAV) route Q-34 in the northeastern United States in support of the Northeast Corridor Atlantic Coast Route Project (NEC ACR) for improved efficiency of the National Airspace System (NAS) while reducing the dependency on ground based navigational systems.

This action amends the Class D and Class E airspace and establishes Class E airspace at airports in Waco, TX. This action is the result of a biennial airspace review. The name and geographic coordinates of various airports are also being updated to coincide with the FAA's aeronautical database.

This action amends the Class D airspace and Class E airspace at Columbus, OH, and revokes the Class E airspace extending upward from 700 feet above the surface at Darby Dan Airport, Columbus, OH. This action is the result of an airspace review caused by the decommissioning of the Rickenbacker International Airport runway 5R middle marker and the cancellation of the instrument procedures at Darby Dan Airport. The name and geographic coordinates of the various airports are also being updated to coincide with the FAA's aeronautical database.

This action amends Class E surface area and Class E airspace extending upward from 700 feet above the surface at Massena International-Richards Field Airport, Massena, NY. The FAA is taking this action as a result of an airspace review caused by the decommissioning of the Massena Very High Frequency Omnidirectional Range (VOR) Tactical Air Navigation (VORTAC) navigation aid as part of the VOR Minimum Operational Network (MON) Program. This action also updates the geographic coordinates of Massena International-Richards Field Airport, Massena, NY, 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.

This action proposes to amend Class E airspace extending upward from 700 feet above the surface for Lake Norman Airpark, Mooresville, NC, by removing Lowe's Mooresville Heliport from the description, as the heliport has closed and airspace is no longer required. This action would enhance the safety and management of controlled airspace within the national airspace system. Also, during the airspace review the FAA determined a radius increase was required at Lake Norman Airpark. In addition, the FAA proposes to remove unnecessary verbiage that references Class E airspace in Statesville, NC, and Concord, NC. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.
