Federal Aviation Administration March 25, 2010 – Federal Register Recent Federal Regulation Documents

The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 186: Automatic Dependent SurveillanceBroadcast (ADS-B).

This action proposes to establish Class E airspace for the Lucin VHF Omni-Directional Radio Range Tactical Air Navigational Aid (VORTAC), Lucin, UT, to facilitate vectoring of Instrument Flight Rules (IFR) traffic from en route airspace to Salt Lake City, UT. This action would enhance the safety and management of IFR operations for the Salt Lake City, UT area.

This action proposes to amend Class E Airspace at Mount Airy, NC, to accommodate the additional airspace needed for the Standard Instrument Approach Procedures (SIAPs) developed for Mount Airy-Surry County Airport. This action enhances the safety and airspace management of Instrument Flight Rules (IFR) operations at the airport.

The FAA proposes to adopt a new airworthiness directive (AD) for PW Model PW2037, PW2037(M), and PW2040 turbofan engines. This proposed AD would require removing erosion damage on fan blades with cutback leading edges and restoring the leading edge contour. This proposed AD results from reports from PW that fan blade leading edge erosion can result in a fan thrust deterioration mode (FTDM) condition, which reduces the engine's capability of producing full rated take-off thrust. We are proposing this AD to prevent loss of engine thrust from an FTDM condition, which could result in an inability to maintain safe flight.

The Federal Aviation Administration (FAA) is considering a proposal to change a portion of the airport from aeronautical use to non-aeronautical use and to authorize the release of 9.167 acres of airport property for future non-aeronautical use. The land consists of portions of 2 original airport acquired parcels. These parcels were acquired by the City of Dayton from the U.S. Government, Department of Housing and Urban Development without federal participation. There are no requirements to retain the land for airport use. There are no impacts to the airport by allowing the City of Dayton to lease the property. The land is not needed for aeronautical use. Approval does not constitute a commitment by the FAA to financially assist in the lease of the subject airport property nor a determination of eligibility for grant-in-aid funding from the FAA. The disposition of proceeds from the lease of the airport property will be in accordance with FAA's Policy and Procedures Concerning the Use of Airport Revenue, published in the Federal Register on February 16, 1999. 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.

We are adopting a new airworthiness directive (AD) for the products listed above. This 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:
