Department of Transportation November 19, 2007 – Federal Register Recent Federal Regulation Documents

In accordance with the Paperwork Reduction Act of 1995 and its implementing regulations, the Federal Railroad Administration (FRA) hereby announces that it is seeking approval of the following information collection activities. Before submitting these information collection requirements for clearance by the Office of Management and Budget (OMB), FRA is soliciting public comment on specific aspects of the activities identified below.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 737-600, 737-700, 737-700C, 737-800, and 737- 900 series airplanes. This proposed AD would require an inspection of the vertical fin lugs, skin, and skin edges for discrepancies, an inspection of the flight control cables, fittings, and pulleys in section 48 for signs of corrosion, an inspection of the horizontal stabilizer jackscrew, ball nut, and gimbal pins for signs of corrosion, and corrective actions if necessary. This proposed AD results from reports indicating that moisture was found within the section 48 cavity. We are proposing this AD to ensure that the correct amount of sealant was applied around the vertical fin lugs, skin and the skin edges. Missing sealant could result in icing of the elevator cables, which could cause a system jam and corrosion of structural and flight control parts, resulting in reduced controllability of the airplane.

This document announces a reopening of the comment period for the above-referenced NPRM. The NPRM proposed the adoption of a new airworthiness directive for all ATR Model ATR42 and ATR72 airplanes. That NPRM invites comments concerning the proposed requirements for revising the Airworthiness Limitations Section of the Instructions for Continued Airworthiness to incorporate new limitations for fuel tank systems. This reopening of the comment period is necessary to provide additional opportunity for public comment on the proposed requirements of that NPRM.

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Boeing Model 767-200, -300, and -300F series airplanes. The existing AD currently requires reworking the surface of the ground stud bracket of the left and right transformer rectifier units (TRUs) and the airplane structure mounting surface, and measuring the resistance from the bracket to the structure and the ground lugs to the bracket using a bonding meter. This proposed AD would revise the applicability of the existing AD to include additional airplanes and would also require, among other actions, installation of a new ground stud bracket using faying surface bonding. This proposed AD results from a report of loss of all direct current (DC) power generation during a flight, due to inadequate electrical ground path between the ground bracket of the TRUs/main battery charger (MBC) and the structure. We are proposing this AD to prevent depletion of the main battery while in flight, resulting from the loss of both TRUs and the MBC, and consequent loss of all DC power, which could impact the safe flight and landing of the airplane due to the loss of function or malfunction of essential/critical systems and displays in the cockpit.

In accordance with the Paperwork Reduction Act of 1995, this notice announces the Maritime Administration's (MARAD's) intention to request extension of approval (with modifications) for three years of a currently approved information collection.

The Federal Aviation Administration (FAA) is issuing this notice to advise the public of the approval of a Finding of No Significant Impact (FONSI) on an Environmental Assessment for proposed Federal actions at Greater Peoria Airport, Peoria, Illinois. The FONSI specifies that the proposed federal actions and local development projects are consistent with existing environmental policies and objectives as set forth in the National Environmental Policy Act of 1969 and will not significantly affect the quality of the environment. A description of the proposed Federal actions is : (a) To issue an environmental finding to allow approval of the Airport Layout Plan (ALP) for the development items listed below; (b) Approval of the Airport Layout Plan (ALP) for the development items listed below; and (c) Establish eligibility of the Greater Peoria Airport Authority to compete for Federal funding for the development projects depicted on the Airport Layout Plan. The specific item in the local airport development project is to acquire approximately 34 acres of land in fee simple title off the Runway 31 end. Copies of the environmental decision and the Short Form EA are available for public information review during regular business hours at the following locations: 1. Greater Peoria Regional Airport, 6100 West Everett McKinley Dirksen Parkway, Peoria, Illinois 61607. 2. Division of Aeronautics-Illinois Department of Transportation, One Langhorne Bond Drive, Capital Airport, Springfield, Illinois 62707. 3. Chicago Airports District Office, Room 320, Federal Aviation Administration, 2300 East Devon Avenue, Des Plaines, Illinois 60018.
