Federal Aviation Administration June 28, 2007 – Federal Register Recent Federal Regulation Documents

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed 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:

The FAA proposes to adopt a new airworthiness directive (AD) for GE CF6-80C2A5F turbofan engines installed on Airbus A300 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.

This action amends Class D airspace at Valdosta, Moody AFB, GA. The Air Education Training Command (AETC) T-6 mission at Moody AFB has been eliminated. Therefore, the requirement for a 7-mile radius of Moody AFB is no longer required. The Moody AFB Class D airspace is amended to airspace upward from the surface up to and including 2,700 MSL within a 5-mile radius of the airport.
