Department of Transportation August 8, 2007 – Federal Register Recent Federal Regulation Documents

In accordance with the Paperwork Reduction Act of 1995, this notice announces the U.S. Department of Transportation's (DOT) intention to request extension of a previously approved information collection.

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:

This amendment establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and/or Weather Takeoff Minimums for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, addition of new obstacles, or changes in air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

DOT is providing notice of a petition from the Board of Commissioners in Perry County, IN, to change the time zone boundary for the County from the Central Time Zone to the Eastern Time Zone, and DOT's request for additional information from Perry County to aid in its determination of whether this change would serve the convenience of commerce, the statutory standard for a time zone change. Other persons supporting or opposing the change to Perry County's time zone boundary are also requested to provide comment. The final rule will be based on all of the information received during the entire rulemaking proceeding and whether the statutory standard has been met.

This action modifies the Phoenix, AZ, Class B airspace area. Specifically, this action lowers the ceiling to 9,000 feet mean sea level (MSL) and expands the arrival extension boundaries to 30 nautical miles (NM). This will ensure the containment of the Standard Terminal Arrival Routes (STAR) at the Phoenix Sky Harbor International Airport (PHX), and correct the inefficiencies of several existing areas identified during public meetings, and reviews of the airspace by the Phoenix Airspace Users Work Group (PAUWG) and Phoenix Terminal Radar Approach Control (TRACON). The FAA is taking this action to improve the flow of air traffic, enhance safety, and reduce the potential for midair collision in the PHX Class B airspace area, while accommodating the concerns of airspace users. Further, this effort supports the FAA's national airspace redesign goal of optimizing terminal and en route airspace areas to reduce aircraft delays and improve system capacity.
