August 11, 2008 – Federal Register Recent Federal Regulation Documents

The Bureau of the Census (Census Bureau) is amending its regulations to establish cutoff dates for the recognition of boundary changes for the 2010 Census. This amendment is necessary, as the existing cutoff dates are out of date. Upon effectiveness of this rule, the Census Bureau will recognize only those boundaries legally in effect on January 1, 2010, that have been reported officially to the Census Bureau no later than March 1, 2010.

The Department of Defense is publishing the unclassified text of a section 36(b)(1) arms sales notification. This is published to fulfill the requirements of section 155 of Public Law 104-164 dated 21 July 1996.

This document makes a correction to Airworthiness Directive (AD) 2008-02-04, which was published in the Federal Register on January 22, 2008 (73 FR 3618), and applies to all Eclipse Aviation Corporation (Eclipse) Model EA500 airplanes. This AD requires incorporating a modification of the angle of attack (AOA) system, limits the applicability to airplanes under S/N 000065, and retains the operating limitations from AD 2007-13-11 until the modification is incorporated. The FAA incorrectly referenced the issue date of the AD as ``January 9, 2007'' instead of ``January 9, 2008.'' This document corrects the issue date.

In accordance with Section 610(b)(2) of the Millennium Challenge Act of 2003 (Pub. L. 108-199, Division D), the Millennium Challenge Corporation (MCC) is publishing a summary and the complete text of the Millennium Challenge Compact between the United States of America, acting through the Millennium Challenge Corporation, and the Republic of Namibia. Representatives of the United States Government and the Republic of Namibia executed the Compact documents on July 28, 2008.

This action modifies Class E Airspace at Rome, New York to support the amendment of the current Terminal Visual Flight Rule (VFR) Radar Service Area (TRSA) and to allow for a lower vectoring altitude known as the Minimum Vectoring Altitude (MVA) for vectoring of both VFR and Instrument Flight Rule (IFR) aircraft around the Rome, NY area. This action will enhance the safety and airspace management around the Griffiss Airport area.

We are adopting a new airworthiness directive (AD) for BHTC Model 222, 222B, and 222U helicopters. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The aviation authority of Canada, with which we have a bilateral agreement, states in the MCAI: ``It has been determined that the existing rigging procedures for the tail rotor pitch change mechanism have to be changed due to possibility of parts interference.'' The cumulative effect of individual part tolerances resulting in the total assemblage of those parts being out of tolerance could result in the tail rotor yoke striking another part other than the flapping stop (parts interference) cited in the MCAI. Also, the misalignment of the tail rotor counterweight bellcrank may result in higher tail rotor pedal forces and a higher pilot workload after failure of the No. 1 hydraulic system. Both parts interference and the misaligned counterweight bellcrank create an unsafe condition. We are issuing this AD to require actions that are intended to address these unsafe conditions.

The FAA is superseding two existing airworthiness directives (ADs), which apply to all Short Brothers Model SD3-60 airplanes. One of the ADs currently requires inspection of the welded joints of the balance weight brackets for the elevator trim tabs for cracking; repetitive inspections, as applicable; and corrective actions including the eventual replacement of all brackets. The other AD currently requires, for certain airplanes, repetitive inspections for cracking of the balance weight brackets and replacement of any cracked bracket, and provides for an optional terminating action for the repetitive inspections. This new AD requires an additional inspection to detect cracks of the balance weight brackets, applicable related investigative and corrective actions, and replacement of a certain balance weight bracket when it has reached its maximum life limit. This AD results from a report indicating that several reworked balance weight brackets have exhibited signs of premature failure. We are issuing this AD to prevent failure of the balance weight brackets of the elevator trim tabs, which could cause loss of the balance weight. This could result in incorrect trim during takeoff and landing, and reduced controllability of the airplane.
