Airworthiness Directives; General Electric Company (GE) CF6-80C2D1F Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for GE CF6-80C2D1F turbofan engines, installed on McDonnell Douglas Corporation MD-11 series airplanes. This proposed AD would require removing previous software versions from the engine electronic control unit (ECU). Engines with new version software will have increased margin to flameout. This proposed AD results from reports of engine flameout events during flight, including reports of events where all engines simultaneously experienced a flameout or other adverse operation. Although the root cause investigation is not yet complete, we believe that exposure to ice crystals during flight is associated with these flameout events. We are proposing this AD to minimize the potential of an all-engine flameout event caused by ice accretion and shedding during flight.
Public Notice for Waiver of Aeronautical Land-Use Assurance; North Vernon Municipal Airport; North Vernon, IN
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 lease of the airport property. The area is a 224-acre parcel of vacant land located west of the airport. The land is presently subject to a farm lease. The land was acquired via quitclaim deed dated February 13, 1948, recorded February 27, 1948, in Jennings County, Deed Record No. 78, Page No. 634-636. There are no impacts to the airport by allowing the airport to lease the property. The land is not needed for aeronautical use, and will be sub-let to various future developers as an industrial airpark. Approval does not constitute a commitment by the FAA to financially assist in the disposal of the subject airport property nor a determination of eligibility for grant-in-aid funding from the FAA. The disposition of the 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.
