Federal Aviation Administration July 6, 2009 – Federal Register Recent Federal Regulation Documents

This action proposes to establish Class E airspace at Chuathbaluk, AK. One Standard Instrument Approach Procedure (SIAP) is being developed for the Chuathbaluk Airport at Chuathbaluk, AK. Adoption of this proposal would result in creating Class E airspace upward from 700 feet (ft.) above the surface at the Chuathbaluk Airport, Chuathbaluk, AK.

This document corrects errors in the FAA regulations regarding amateur rockets. A section concerning unmanned rocket activities was inadvertently placed in the subpart for unmanned balloon activities. This correction moves that section to the correct subpart, so all the information relating to unmanned rocket activities will appear in the same subpart. Additionally, we are making minor editorial corrections.

We propose to adopt a new airworthiness directive (AD) for all Boeing 747-200C and -200F series airplanes. This proposed AD would require a high frequency eddy current inspection for cracks of certain fastener holes, and corrective action if necessary. This proposed AD would also require repetitive replacements of the upper chords, straps (or angles), and radius fillers of certain upper deck floor beams, and, for any replacement that is done, detailed and open-hole HFEC inspections for cracks of the modified upper deck floor beams, and corrective actions if necessary. This proposed AD results from a report from the manufacturer that the accomplishment of certain existing inspections, repairs, and modifications is not adequate to ensure the structural integrity of the affected 7075 series aluminum alloy upper deck floor beam upper chords on airplanes that have exceeded certain thresholds. We are proposing this AD to prevent cracking of the upper chords and straps (or angles) of the floor beams, which could lead to failure of the floor beams and consequent loss of controllability, rapid decompression, and loss of structural integrity of the airplane.

This action amends Class E airspace at Port Clinton, OH. Additional controlled airspace is necessary to accommodate Area Navigation (RNAV) Standard Instrument Approach Procedures (SIAP) at Carl R. Keller Field Airport, Port Clinton, OH. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at Carl R. Keller Field Airport.

This action establishes twenty two Area Navigation (RNAV) routes, and revises fourteen RNAV routes, in the State of Alaska. Additionally, this action removes four existing routes that are no longer required. Q & T-routes are Air Traffic Service (ATS) routes, based on RNAV, for use by aircraft having instrument flight rules (IFR)-approved Global Positioning System (GPS)/Global Navigation Satellite System (GNSS) equipment. The FAA is taking this action to enhance safety and to improve the efficient use of the navigable airspace in Alaska.
