Proposed Amendment of Class E Airspace; Casper, WY
This action proposes to modify the Class E airspace areas at Casper, Natrona County International Airport, Casper, WY, to facilitate vectoring of Instrument Flight Rules (IFR) traffic from en route airspace to the airport. Decommissioning of the Muddy Mountain VOR Omnidirectional Range Tactical Air Navigation (VORTAC) has made reconfiguration necessary for the safety and management of aircraft operations at Casper, Natrona County International Airport, Casper, WY.
Public Notice for Waiver of Aeronautical Land-Use Assurance; J. Douglas Bake Memorial Airport (OCQ) Oconto, WI
The Federal Aviation Administration (FAA) is considering a proposal to authorize the release of 0.32 acres of airport property (Parcel No. 18) at the J. Douglas Bake Memorial Airport, Oconto, WI. Parcel No. 18 is located outside of the airport fence along the west edge of the airport and contains a part of a road used to access a land-locked parcel of private property located adjacent to the airport. Using the piece of airport property as an uncontrolled access road has resulted in a non-aeronautical use of airport property and a compliance issue for the airport. In addition, the uncontrolled access raises liability concerns for the airport. The land release would bring the airport into compliance with grant assurances and assure compatible land use. It would also remove the liability issue related to the unauthorized use of the access road. A categorical exclusion for this land release action was prepared by Wisconsin Dept. of Transportation-Bureau of Aeronautics and issued on June 22, 2011. The aforementioned land is not needed for aeronautical use. The parcel is depicted on the Airport Layout Plan and Exhibit ``A'' property map dated July 12, 2011. There are no impacts to the airport by allowing the airport to dispose of this parcel. The subject parcel was originally acquired on September 10, 2002, as part of Airport Improvement Program grant No. 04 and is described in the warranty deed recorded in Volume 933 pages 480-481, Oconto County, Wisconsin. The value of the parcel is $600. In accordance with section 47107(h) of title 49, United States Code, this notice is required to be published in the Federal Register 30 days before modifying the land-use assurance that requires the property to be used for an aeronautical purpose.
Airworthiness Directives; Pratt & Whitney Division Turbofan Engines
We are adopting a new airworthiness directive (AD) for all Pratt & Whitney Division PW4050, PW4052, PW4056, PW4060, PW4060A, PW4060C, PW4062, PW4062A, PW4152, PW4156, PW4156A, PW4158, PW4160, PW4460, PW4462, and PW4650 turbofan engines, including models with any dash number suffix. This AD was prompted by 16 reports of damaged or failed 3rd stage low-pressure turbine (LPT) duct segments. This AD requires removing from service certain part numbers (P/Ns) of 3rd stage LPT duct segments. We are issuing this AD to prevent failure of the 3rd stage LPT duct segments, which could lead to LPT rotor damage, uncontained engine failure, and damage to the airplane.
Airworthiness Directives; PIAGGIO AERO INDUSTRIES S.p.A Airplanes
We are revising an existing airworthiness directive (AD) for certain Piaggio Aero Industries S.p.A. Model P-180 airplanes. That AD currently requires replacement of any firewall shutoff or crossfeed valve with a serial number in a certain range even if it has been previously modified. The way the applicability was written includes valves that should not be affected and are not included in the referenced service information. This AD requires the same actions as the current AD, but only affects those firewall shutoff valves referenced in the referenced service information. We are issuing this AD to clarify the affected parts required to correct the unsafe condition on these products.
