Modification to Restricted Areas R-3602A and R-3602B; Manhattan, KS
This action amends Restricted Areas R-3602A and R-3602B, Manhattan, KS, to accurately identify the R-3602A and R-3602B boundary segments described using the Chicago, Rock Island and Pacific Railroad right-of-way, the R-3602A and R-3602B shared boundary segment described using Old U.S. Highway 77, and the R-3602A and Riley Military Operations Area (MOA) shared boundary segment described using the Milford Reservoir shoreline. The restricted area ceilings are also amended to be expressed as flight levels (FL), the Marshall Army Air Field Radio Beacon (RBN) referenced in R-3602B is changed to the Cavalry Nondirectional Beacon (NDB), and the restricted areas using agency information is updated to include the military service of the using agency. This action does not affect the overall restricted area boundaries, designated altitudes, times of designation, or activities conducted within the restricted areas. Additionally, boundary segment amendments of the Riley MOA, ancillary to the restricted area amendments, are being made. Since the R-3602A and R-3602B restricted areas share boundaries with the Riley MOA, the FAA included discussion of the Riley MOA amendments in this rule. Lastly, the MOA using agency is being amended to match the restricted areas using agency information.
Notice of Availability of the Final Re-Evaluation of the O'Hare Modernization Environmental Impact Statement (Final Re-Evaluation)
The Federal Aviation Administration (FAA) announces that the Final Written Re-Evaluation of the O'Hare Modernization Environmental Impact Statement (Final Re-Evaluation) for Chicago O'Hare International Airport, Chicago, Illinois is available. The Final Re-Evaluation identifies the potential environmental impacts associated with the construction schedule modification that alters the timing for commissioning new Runway 10R/28L, new Runway 9C/ 27C, and the extension of Runway 9R/27L at O'Hare International Airport pursuant to the National Environmental Policy Act.
Airworthiness Directives; Piper Aircraft, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc. Models PA-28-161, PA-28-181, and PA-28R-201 airplanes. This AD requires inspecting the right wing rib at wing station 140.09 for cracks and taking necessary corrective action. This AD was prompted by a report of cracks found in the wing rib bead radius that were formed during production. We are issuing this AD to correct the unsafe condition on these products.
Airworthiness Directives; General Electric Company Turboshaft Engines
We are superseding airworthiness directives (AD) 2001-18-06 and AD 2008-22-16, for all General Electric Company (GE) CT58 turboshaft engines. AD 2001-18-06 and AD 2008-22-16 required recalculating the lives of life-limited rotating parts using a repetitive heavy-lift (RHL) multiplying factor and removal from service of parts that exceed the recalculated cyclic or hourly life limit. This new AD would consolidate AD 2001-18-06 and AD 2008-22-16, and further reduce the life capability of certain parts. This AD was prompted by recalculation of life for parts installed on engines used in Utility operations, and a reduced life for compressor spools in all operations. We are issuing this AD to prevent failure of life-limited rotating parts, uncontained part release, damage to the engine, and damage to the aircraft.
Airworthiness Directives; Pratt & Whitney Canada Corp. Turboprop Engines
We are superseding airworthiness directive (AD) 2014-14-02 for certain Pratt & Whitney Canada Corp. (P&WC) PW120, PW121, PW121A, PW124B, PW127, PW127E, PW127F, PW127G, and PW127M turboprop engines. AD 2014-14-02 required removal of the O-ring seal from the fuel manifold fitting. This new AD requires replacement of the fuel nozzle and the fuel manifold flow adapter. This AD was prompted by reports of fuel leaks at the interface between the fuel manifold and the fuel nozzle that resulted in engine fire. We are issuing this AD to correct the unsafe condition on these products.
Airworthiness Directives; Pratt & Whitney Canada Corp. Turboshaft Engines
We are adopting a new airworthiness directive (AD) for certain Pratt & Whitney Canada Corp. (P&WC) PT6B-37A turboshaft engines. This AD requires initial and repetitive inspections until replacement of the No. 10 bearing, and eventual replacement of the No. 9 bearing, both located in the engine reduction gearbox (RGB) assembly. This AD was prompted by reports of incorrect engine torque for PT6B-37A engines. We are issuing this AD to prevent axial migration of the No. 10 bearing in the engine RGB assembly, which could result in engine overtorque, failure of the engine, in-flight shutdown, and loss of the rotorcraft.
Airworthiness Directives; Schempp-Hirth Flugzeugbau GmbH Sailplanes
We are adopting a new airworthiness directive (AD) for Schempp-Hirth Flugzeugbau GmbH Models Duo Discus and Duo Discus T powered sailplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 excessive load on the air brake system. We are issuing this AD to require actions to address the unsafe condition on these products.
