The FAA is issuing this notice to advise the public of a meeting of Twenty First RTCA SC-223 Internet Protocol Suite (IPS) and AeroMACS Plenary.
Sixty Ninth Plenary for RTCA SC-135 Environmental Testing
The FAA is issuing this notice to advise the public of a meeting of Sixty Ninth Plenary RTCA SC-135 Environmental Testing.
Proposed Amendment of Class D and Class E Airspace; Hailey, ID
This action proposes to modify Class D airspace, Class E surface area airspace, and Class E airspace extending upward from 700 feet above the surface at Friedman Memorial Airport, Hailey, ID, to support the implementation of new Area Navigation (RNAV) Global Positioning System (GPS) standard instrument approach procedures for Instrument Flight Rules (IFR) at the airport.
Airworthiness Directives; General Electric Company Turbofan Engines
We propose to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) CF6-80C2L1F turbofan engines. This proposed AD was prompted by a reduction in the life limit of the affected engines which is the result of a revised operating profile. This proposed AD would require replacement of the high-pressure turbine (HPT) spacer/impeller, part number (P/N) 1539M12P02, at a newer, lower life limit. We are proposing this AD to correct the unsafe condition on these products.
Proposed Establishment of Class E Airspace, Manti, UT
This supplemental notice of proposed rulemaking would establish Class E airspace upward from 700 feet above the surface within a 4.7-mile radius of Manti-Ephraim Airport, Manti, UT, with segments extending north and southwest of the airport. In an NPRM published in the Federal Register on November 22, 2016, the FAA proposed to establish Class E airspace extending upward from 700 feet above the surface within a 4-mile radius of Manti-Ephraim Airport, with extensions north and southwest. The FAA found additional airspace is necessary for new category D circling Instrument Flight Rules (IFR) operations for standard instrument approach procedures and to support the safety and management of IFR operations at the airport.
