This supplemental NPRM revises an earlier proposed airworthiness directive (AD), for certain CFM International, S.A. models CFM56-3 and -3B turbofan engines. That proposed AD would have required initial and repetitive inspections for damage to the fan blades. That proposed AD resulted from a report of a failed fan blade with severe out-of-limit wear on the underside of the blade platform where it contacts the damper. This supplemental NPRM revises the proposed AD to reduce the initial inspection compliance threshold, to correct the engine model designations affected, and to clarify some of the inspection wording in the compliance section. This supplemental NPRM results from a report of a failed fan blade with severe out-of- limit wear on the underside of the blade platform where it contacts the damper. We are proposing this supplemental NPRM to prevent failure of multiple fan blades, which could result in an uncontained failure of the engine and damage to the airplane.

In accordance with National Environmental Policy Act regulations of 1969, as amended (NEPA) (42 U.S.C. 4321 et seq.), Council on Environmental Quality NEPA implementing regulations (40 CFR parts 1500-1508), and FAA Order 1050.1E, Change 1, the FAA is announcing the availability of and requesting comments on the Draft Supplemental Environmental Assessment (SEA) to the September 2008 Environmental Assessment for Space Florida Launch Site Operator License. The Draft SEA was prepared in response to an application for a Launch Site Operator License from Space Florida. Under the Proposed Action, the FAA would issue a Launch Site Operator License to Space Florida to operate a commercial space launch site at Launch Complex 36 (LC-36) and LC-46 at Cape Canaveral Air Force Station (CCAFS) in Brevard County, Florida. The license would allow Space Florida to support vertical launches of both solid and liquid propellant launch vehicles from LC-36 and LC-46. LC-46 is the easternmost launch complex at CCAFS, located at the tip of Cape Canaveral, and LC-36 is located in
