Department of Transportation June 11, 2010 – Federal Register Recent Federal Regulation Documents

The Surface Transportation Board seeks comments on a request from the Association of American Railroads that the Board restate the previously published productivity adjustment for the 2003-2007 averaging period (2007 productivity adjustment) so that it tracks the 2007 productivity adjustment figure used in the Board's March 26, 2010 calculation of the modified 2008 productivity adjustment, and restate any quarterly RCAF (Adjusted) and RCAF-5 calculations that would be affected by a restatement of the 2007 productivity adjustment.

This action modifies Jet Routes J-32 and J-38 by terminating portions of the routes that are no longer needed at the Duluth, MN, VHF omnidirectional range/tactical air navigation (VORTAC) that are no longer needed. This action also modifies the J-538 airway description to align it with the corresponding segment of J-538 contained in Canadian airspace. This action is necessary for the safety and management of instrument flight rules (IFR) operations within the National Airspace System (NAS).

The FAA publishes a monthly notice, as appropriate, of PFC approvals and disapprovals under the provisions of the Aviation Safety and Capacity Expansion Act of 1990 (Title IX of the Omnibus Budget Reconciliation Act of 1990) (Pub. L. 101-508) and Part 158 of the Federal Aviation Regulations (14 CFR Part 158). This notice is published pursuant to paragraph d of Sec. 1A158.29.

This amendment supersedes an existing airworthiness directive (AD) for the specified Bell Helicopter Textron Canada (BHTC) helicopters, that currently requires certain checks and inspections of the tail rotor blades. If a crack is found, the existing AD requires replacing the tail rotor blade (blade) with an airworthy blade before further flight. This amendment requires the same checks and inspections of the blades until they are required to be replaced and removes certain serial numbered and specifically coded blades from the applicability of the AD. This amendment is prompted by the approved rework of certain blades and two newly redesigned blades, which, if installed, constitute terminating action for the inspection requirements. The actions specified by this AD are intended to detect a crack in a blade, and to prevent loss of a blade and subsequent loss of control of the helicopter.
