Airworthiness Directives; Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes
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 reports of the failure of emergency locator transmitter (ELT) antennas. This AD requires repetitive replacements of the ELT antenna and repetitive inspections for damage of the exterior fuselage skin around the ELT antenna attachment area, as specified in a Transport Canada Civil Aviation (TCCA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Agency Information Collection Activities: Requests for Comments; Clearance of a Renewed Approval of Information Collection: Commercial Air Tour Limitations in the Grand Canyon National Park Special Flight Rules Area
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 Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on November 23, 2020. The FAA will use the information it collects and reviews to monitor compliance with the regulations regarding air tours in the Grand Canyon National Park.
Special Conditions: Airbus Helicopters Model H160B Helicopter; Use of 30-Minute All Engines Operating Power Rating
These special conditions are issued for the Airbus Helicopters (Airbus) Model H160B helicopter. This model helicopter will have a 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.
Amendment of Class E Airspace; Kremmling, CO
This action modifies the Class E airspace extending upward from 700 feet above the surface at Mc Elroy Airfield Airport, Kremmling, CO. Modification of this airspace is necessary to properly contain instrument flight rules (IFR) aircraft departing and arriving at the airport. Additionally, this action implements administrative updates to the airport's name and geographic coordinates.
Amendment of Class E Airspace; Meeker, CO
This action modifies the Class E airspace extending upward from 700 feet above the surface at Meeker Coulter Field Airport, Meeker, CO, by reducing the dimensions of the airspace area. Additionally, this action implements an administrative update to the airport's name.
Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments
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.

Airworthiness Directives; Leonardo S.p.a. Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for all Leonardo S.p.a. Model AW189 helicopters. This proposed AD was prompted by the identification of misleading information in the emergency procedure for the ``1(2) FUEL LOW'' caution message. This proposed AD would require revising the existing Rotorcraft Flight Manual (RFM) for your helicopter. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters Deutschland GmbH (AHD) Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH (AHD) Model BO-105A, BO-105C, BO-105S, and BO-105LS A-3 helicopters equipped with a certain hoist system. This AD was prompted by an uncommanded activation of the hoist cable cutter function on an MBB-BK117 C-1 helicopter, which prompted a design review of the BO105 hoist control grip with coiled cable. This proposed AD would require inspections of the hoist control grip with coiled cable and deactivation of the hoist cuter function, 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.
Airworthiness Directives; Leonardo S.p.a. (Type Certificates Previously Held by Agusta S.p.A. and AgustaWestland S.p.A.) Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for Leonardo S.p.a. (Type Certificate previously held by Agusta S.p.A.) Model AB139 and AW139 helicopters and Leonardo S.p.a. (Type Certificate previously held by AgustaWestland S.p.A.) Model AW189 helicopters. This proposed AD was prompted by reports of missing lock wire and loose fasteners. This proposed AD would require a one-time inspection of the main rotor (M/R) slip ring and depending on the outcome, removing the M/R slip ring from service, removing screws and washers from service, applying torque, installing lock wire, and re-identifying the M/R slip ring. This proposed AD would also prohibit the installation of certain M/R slip rings. The FAA is proposing this AD to address the unsafe condition on these products.
