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

We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. 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 supersede an existing airworthiness directive (AD) that applies to certain Model 747-100, 747-200B, and - 200F series airplanes. The existing AD currently requires inspections to detect cracking in the upper row of fasteners holes of the skin lap joints in the fuselage lower lobe, and repair, if necessary. This proposed AD would reduce the maximum interval of the post-modification inspections. This proposed AD results from reports of fatigue cracking on modified airplanes. We are proposing this AD to detect and correct fatigue cracking in the longitudinal lap joints of the fuselage lower lobe, which could lead to the rapid decompression of the airplane and the inability of the structure to carry fail-safe loads.

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: During a maintenance check performed by an A310 operator, the recommended modification of the lower attachment beam of rack 101VU by accomplishment of Airbus Service Bulletin (SB) A310-53-2076 was embodied on the aeroplane, leading the operator to find three cracks on the FR15A crossbeam above the NLG [nose landing gear] box at the splicing with rack 107VU fitting. This condition, if not detected and corrected, could degrade the structural integrity of the crossbeam on NLG FR15A web attachment fitting of rack 107VU. Rack 107VU contains major airworthiness system components whose functioning could be adversely affected by the loss of the attachment fitting. As the A300 and A300-600 aeroplanes share this design feature, they are also affected. The proposed AD would require actions that are intended to

This action amends Class E airspace for Llano, TX, adding additional controlled airspace to accommodate Area Navigation (RNAV) Standard Instrument Approach Procedures (SIAPs) at Llano Municipal Airport, Llano, TX, and updates the airport's geographic coordinates. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at the airport.

This action amends Class E airspace for Stamford, TX, adding additional controlled airspace to accommodate Area Navigation (RNAV) Standard Instrument Approach Procedures (SIAPs) at Arledge Field Airport, Stamford, TX. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at the airport.
