Airworthiness Directives; Airbus Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model EC155B1 helicopters. This proposed AD was prompted by reports of failure of the main gearbox (MGB) oil cooling fan hub (fan hub). This proposed AD would require for helicopters with an affected part (fan hub) installed, using an endoscope, repetitively inspecting the fan hub, including the area around the fan hub attachment screws, for a crack. Depending on the inspection results, this proposed AD would require performing additional inspections and replacing an affected fan hub. This proposed AD would also allow an affected fan hub to be installed on a helicopter if certain actions are accomplished, 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.
Notice of Final Policy and Procedures on the Temporary Closure of Airports for Nonaeronautical Purposes
This notice announces the Final Policy and procedures for an airport sponsor requesting approval of the temporary closure of a federally obligated airport for a nonaeronautical purpose. Under federal law, the Secretary of Transportation may approve a project grant application for an airport development project only if the Secretary receives written assurances that a proposal to close the airport temporarily for a nonaeronautical purpose must first be approved by the Secretary. Airport operators that have accepted Federal financial assistance are obligated to maintain the airport for public aviation use. Under certain conditions, an airport sponsor may temporarily close the airport or part of the airport for a nonaeronautical event, if the FAA approves the airport sponsor's request in advance of a nonaeronautical event. The Secretary's review and approval, delegated to the Federal Aviation Administration, constitutes a Federal Action that requires an assessment under the National Environmental Policy Act. The FAA adopts this policy statement to provide additional guidance for airport operators to comply with the requirements of the statute and obtain an FAA decision in a timely manner for the conduct of their nonaeronautical event at the airport.
Special Conditions: Airbus Helicopters Model H160B Helicopter; Extended Duration of Flight After Loss of Main Gearbox Lubrication
This action proposes special conditions for the Airbus Helicopters (Airbus) Model H160B helicopter. This helicopter will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for helicopters. This design feature is the extended duration of safe flight beyond 30 minutes after the loss of main gearbox lubrication. 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.
Amendment of Class D and Class E Airspace; Beaufort, SC
This action amends Class D airspace, Class E surface airspace, and Class E airspace extending upward from 700 feet above the surface at Beaufort Marine Corps Air Station (MCAF)/Merritt Field, Beaufort, SC, by updating the airport's geographic coordinates. This action also updates the name of Beaufort Executive Airport (formerly Beaufort Count Airport) and removes unnecessary verbiage from the Class E airspace extending upward from 700 feet above the surface. In addition, this action makes the editorial changes replacing the term Notice to Airmen with Notice to Air Missions and replacing the term Airport/Facility Directory with Chart Supplement. This action does not change the airspace boundaries or operating requirements.
Modification of Class E Airspace; Ralph M. Calhoun Memorial Airport, Tanana, AK
This action proposes to modify the Class E airspace designated as a surface area and modify the Class E airspace extending upward from 700 feet above the surface at Ralph M. Calhoun Memorial Airport, Tanana, AK. Additionally, this action proposes several administrative amendments to update the airport's existing Class E airspace legal descriptions. These actions would support the safety and management of instrument flight rules (IFR) operations at the airport.
Airworthiness Directives; MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all MHI RJ Aviation ULC Model CL-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-2D15 (Regional Jet Series 705), CL-600-2D24 (Regional Jet Series 900), and CL-600-2E25 (Regional Jet Series 1000) airplanes. This proposed AD was prompted by a manufacturing quality escape concerning the installation of the Halon metering device on certain cargo fire extinguisher containers. This proposed AD would require the inspection of cargo fire extinguisher container serial numbers and the replacement of the affected containers. This proposed AD would also limit the installation of affected parts. The FAA is proposing this AD to address the unsafe condition on these products.
