Department of Transportation May 2010 – Federal Register Recent Federal Regulation Documents

We propose to supersede an existing airworthiness directive (AD) for Tay 650-15 turbofan engines. That AD currently requires initial and repetitive inspections of the low-pressure (LP) turbine discs stage 2 and stage 3 for corrosion, on certain Tay 650-15 serial number engines. This proposed 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 MCAI describes the unsafe condition as: Strip results from some of the engines listed in the applicability section of this AD revealed excessively corroded low-pressure turbine disks stage 2 and stage 3. The corrosion is considered to be caused by the environment in which these engines are operated. Following a life assessment based on the strip findings it is concluded that inspections for corrosion attack are required. The action specified by this European Aviation Safety Agency (EASA) AD 2008-0122 was intended to avoid a failure of a low- pressure turbine disk stage 2 or stage 3 due to potential corrosion problems which could result in uncontained engine failure and damage to the airplane. It has been later realized that the same unsafe condition could potentially occur on more serial numbers for the Tay 650-15 engines and on the Tay 651-54 engines. This AD, superseding EASA AD 2008-0122, retaining its requirements, is therefore issued to expand the Applicability in adding further engine serial numbers for the Tay 650-15 engines and in adding the Tay 651-54 engines.

In compliance with the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.), this notice announces that the Information Collection Request (ICR) abstracted below has been forwarded to the Office of Management and Budget (OMB) for review and comment. The ICR describes the nature of the information collection and the expected burden. The Federal Register Notice with a 60-day comment period was published on February 24, 2010 (75 FR 8426-8472).

This action modifies Jet Route J-3 by terminating the route at the Spokane, WA, VHF omnidirectional range/tactical air navigation (VORTAC) instead of the Canadian border. This action is necessary for the safety and management of instrument flight rules (IFR) operations within the National Airspace System (NAS).

This action extends the comment period for a NPRM that was published on March 12, 2010. In that document, the FAA proposed to amend the airworthiness standards for fatigue tolerance evaluation (FTE) of transport category metallic rotorcraft structures. This notice responds to a request from the European Aviation Safety Agency (EASA) to extend the comment period to the proposal.

We are adopting a new airworthiness directive (AD) for the products listed above. This 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:

We are adopting a new airworthiness directive (AD) for certain Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, DC-10-40F, MD-10-10F, MD-10-30F, MD-11, and MD-11F airplanes. This AD requires a one-time installation of electrical bonding jumpers for the fill valve controllers of fuel tanks. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent point-of-contact arcing or filament heating damage in the fuel tanks, which could result in fuel tank explosions and consequent loss of the airplane.

This document corrects a typographical error that appeared in airworthiness directive (AD) 2002-23-20 that was published in the Federal Register on November 29, 2002 (67 FR 71098). The typographical error resulted in an incorrect part number. This AD is applicable to Model FALCON 900EX and MYSTERE-FALCON 900 airplanes. This AD requires repetitive operational tests of the flap asymmetry detection system to verify proper functioning, and repair if necessary; repetitive replacement of the inboard flap jackscrews with new or reconditioned jackscrews; and repetitive measurement of the screw/nut play of the jackscrews on the inboard and outboard flaps to detect discrepancies, and corrective action if necessary. This AD also requires revision of the Airplane Flight Manual.

In accordance with the Paperwork Reduction Act of 1995 and its implementing regulations, the Federal Railroad Administration (FRA) hereby announces that it is seeking renewal of the following currently approved 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.

This action amends Class E airspace for Emmetsburg, IA, adding additional controlled airspace to accommodate Area Navigation (RNAV) Standard Instrument Approach Procedures (SIAPs) at Emmetsburg Municipal Airport, Emmetsburg, IA. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at the airport.

This action amends Class E airspace for Mapleton, IA, adding additional controlled airspace to accommodate Area Navigation (RNAV) Standard Instrument Approach Procedures (SIAPs) at James G. Whiting Memorial Field Airport, Mapleton, IA. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at the airport.

The FAA proposes to rule and invite public comment on the release of land at the Reading Regional Airport, Reading, Pennsylvania under the provisions of Section 47125(a) of Title 49 United States Code (U.S.C.).

The FAA is superseding an existing airworthiness directive (AD) for CFM International, S.A. CFM56-5B series turbofan engines. That AD requires reviewing exhaust gas temperature (EGT) monitoring records to determine EGT margin deterioration, and for airplanes where both engines have greater than 80 [deg]centigrade (C) of EGT margin deterioration, borescope-inspecting the high-pressure compressor (HPC) of both engines. That AD also requires removing from service any engine that does not pass the borescope inspection and, if both engines pass, replacing one of the engines with an engine that has 80 [deg]C or less of EGT margin deterioration. That AD also requires continuous monitoring of EGT margin deterioration on engines in service to prevent two engines on an airplane from having greater than 80 [deg]C of EGT margin deterioration. This AD:

The Department of Transportation (DOT), Office of the Secretary (OST), Office of Small and Disadvantaged Business Utilization (OSDBU) announces the opportunity for; (1) Business centered community- based organizations; (2) transportation-related trade associations; (3) colleges and universities; (4) community colleges or; (5) chambers of commerce, registered with the Internal Revenue Service as 501 C(6) or 501 C(3) tax-exempt organizations, to compete for participation in OSDBU's Small Business Transportation Resource Center (SBTRC) program in the Central Region, the Southeast Region, and the West Central Region. The Southwest, South Atlantic, and Mid-South Atlantic Regions have previously been competed in Fiscal Year 2010. The Great Lakes, Gulf, Mid Atlantic, Northeast, and Northwest Regions will be competed at a later date as their cooperative agreements expire.
