Public Notice for Waiver of Aeronautical Land Use Assurance, Arlington Municipal Airport, Arlington, WA
Notice is being given that the FAA is considering a proposal from the City of Arlington Airport Director to change certain portions of the airport from aeronautical use to non-aeronautical use at Arlington Municipal Airport, Arlington, WA. The proposal consists of approximately 52,500 square feet on the west side of the airfield adjacent to 51st Avenue, Northeast.
Airworthiness Directives; Pacific Aerospace Limited Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Pacific Aerospace Limited Model 750XL airplanes. This proposed AD results from 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 airplane sound insulation materials attached to the aft face of the firewall not complying with the applicable burn testing criteria for materials on the cabin side of the firewall. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; Pratt & Whitney
We propose to adopt a new airworthiness directive (AD) for all Pratt & Whitney (PW) PW2037, PW2037M, and PW2040 turbofan engines. This proposed AD was prompted by an uncommanded high thrust event that occurred during approach on January 16, 2016, and during landing on April 6, 2016. This proposed AD would require removal of the metering valve pilot valve (MVPV) within certain fuel control units (FCUs) and the MVPV's replacement with a part eligible for installation. We are proposing this AD to address the unsafe condition on these products.
Proposed Establishment of the Hawaiian Islands High and the Hawaiian Islands Low Offshore Airspace Areas; Hawaii.
This action proposes to establish the Hawaiian High and Hawaiian Low Offshore airspace area. The proposed action would establish Class A airspace extending upward from 18,000 feet mean sea level (MSL) to and including flight level (FL) 600; and Class E airspace, extending upward from 1,200 feet MSL to and including 17,999 feet MSL around the Hawaiian Islands. The FAA is proposing this action to provide additional airspace within which domestic air traffic control (ATC) procedures would be used. Establishment of the Class A and Class E airspaces would enhance the management of air traffic operations and result in more efficient use of that airspace.
List of Units of the National Park System Exempt From the Provisions of the National Parks Air Tour Management Act
The National Parks Air Tour Management Act (NPATMA) requires the Federal Aviation Administration (FAA) and National Park Service (NPS) to develop an air tour management plan for units of the national park system where an operator has applied for authority to conduct commercial air tours. The FAA Modernization and Reform Act of 2012 amended various provisions of NPATMA. One provision exempted national park units with 50 or fewer annual flights from the requirement to prepare an air tour management plan or voluntary agreement and requires FAA and NPS to jointly publish a list of exempt parks. By Federal Register notice, FAA and NPS published an initial list of exempt parks in 2012 and subsequent lists for 2013 through 2015. This notice provides the annual updated list of parks that are exempt.
Airworthiness Directives; Agusta S.p.A. Helicopters
We are adopting a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model A109E, A109K2, A109S, AW109SP, A119, and AW119 MKII helicopters. This AD reduces the life limit of and requires inspecting a tail rotor blade retention bolt (bolt). This AD is prompted by the discovery of a cracked bolt. The actions of this AD are intended to address an unsafe condition on these products.
