Federal Aviation Administration December 14, 2020 – Federal Register Recent Federal Regulation Documents

The FAA proposes to supersede Airworthiness Directive (AD) 2016-23-05, which applies to certain Airbus Helicopters Model SA-365N1, AS-365N2, AS 365 N3, SA-366G1, EC 155B, and EC155B1 helicopters. AD 2016-23-05 requires repetitive checks of the oil level of the tail rotor gearbox and, if necessary, filling the oil to the maximum level; and replacement of a certain control rod double bearing (bearing) with a new bearing. Since issuing AD 2016-23-05, the FAA has determined additional inspections, replacements, and modifications are necessary to address the unsafe condition. This proposed AD would retain the requirements of AD 2016-23-05 and would add helicopters to the applicability. This proposed AD would also require modifying the helicopter by replacing the tail gearbox (TGB) control shaft guide bushes; repetitive inspections of the TGB magnetic plug and corrective actions if necessary; repetitive replacements of the bearing; and modifying the helicopter by replacing the TGB; 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.

This notice announces a meeting of the Women in Aviation Advisory Board (WIAAB).

This action modifies two high altitude United States Area Navigation (RNAV) Air Traffic Service (ATS) routes (Q-13 and Q-15), establishes one high altitude RNAV ATS route (Q-174), and establishes five low altitude RNAV ATS routes (T-338, T-357, T-359, T-361, and T- 363) in the western United States. These Q and T routes facilitate the movement of aircraft to, from, and through the Las Vegas terminal area. Additionally, the routes promote operational efficiencies for users and provide connectivity to RNAV enroute procedures while enhancing capacity for adjacent airports.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Garmin International (Garmin) GMN-00962 GTS processor units (GTS 825, GTS 855, GTS 8000). This proposed AD was prompted by reports of GTS processor units issuing resolution advisories (RAs) when no risk of collision or loss of separation exists between the airplanes involved. This proposed AD would require updating the software version of the affected GTS Processor units. The FAA is proposing this AD to address the unsafe condition on these products.

This action modifies the Class D airspace at Glacier Park International Airport. This action also modifies the Class E airspace, designated as a surface area. Additionally, this action modifies the Class E airspace, extending upward from 700 feet above the surface. Further, this action modifies the Class E airspace, extending upward from 1,200 feet above the surface. This action also removes the Smith Lake NDB from the Class E airspace legal descriptions. Lastly, this action implements several administrative corrections to the airspaces' legal descriptions.

The FAA proposes to supersede Airworthiness Directive (AD) AD 2019-12-09, which applies to certain Rockwell Collins, Inc. (Rockwell Collins) FDSA-6500 flight display system applications installed on airplanes. AD 2019-12-09 imposes 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 proposed AD would retain the requirements of AD 2019-12-09 until a software upgrade is completed. The FAA is proposing this AD to address the unsafe condition on these products.
