We propose to adopt a new airworthiness directive (AD) for certain serial number Pratt & Whitney Canada Corp. (P&WC) PW206B, PW206B2, PW206C, PW207C, PW207D, PW207D1, PW207D2, and PW207E turboshaft engines. This proposed AD was prompted by the discovery that certain power turbine (PT) disks were made to specific heat codes that may not achieve the maximum in-service life. This proposed AD would require re-identification of the PT disk to a part number (P/N) with a lower life limit. We are proposing this AD to prevent possible uncontained PT disk failure and loss of helicopter control.

We propose to supersede an existing airworthiness directive (AD) that applies to certain The Boeing Company Model 737-200, -200C, - 300, -400 and -500 series airplanes. The existing AD currently requires a one-time mid-frequency eddy current (MFEC) inspection, a low frequency eddy current (LFEC) inspection, and a detailed inspection for damage or cracking of stringer S-4L and S-4R lap joints and stringer clips between body station (BS) 540 and BS 727, and follow-on inspections and repair if necessary. Since we issued that AD, we have received reports of cracking of the lap joint lower row. This proposed AD would instead require repetitive external eddy current inspections for cracking of certain fuselage crown lap joints and corrective actions; internal eddy current and detailed inspections for cracking of certain fuselage crown lap joints, and repair if necessary; and detailed inspections of certain stringer clips, and replacement with new stringer clips if necessary. This proposed AD would also add airplanes to the applicability. We are proposing this AD to detect and correct cracking of the fuselage lap joints, which could result in sudden decompression of the airplane.

We propose to adopt a new airworthiness directive (AD) for certain Model A330-200, -300 and -200 Freighter series airplanes; and all Model A340-200 and -300 series airplanes. This proposed AD was prompted by a determination that the bonding lead from a certain isolation valve to a frame was too close to an electrical harness, which might cause chafing between the electrical harness and the associated bonding lead. This chafing could lead to a short circuit of the isolation valve and consequent non-closure of the isolation valve, which would prevent the air-flow to be shut-off in case of fire. This proposed AD would require modifying the bonding lead installation of the isolation valve. We are proposing this AD to prevent such chafing, which could result in non-closure of the isolation valve in the event of a fire and consequent damage to the airplane and injury to its occupants.

We propose to adopt a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) BR700-710 series turbofan engines. This proposed AD was prompted by service experience that demonstrated premature wear of the splined coupling on the fuel pump. This proposed AD would require replacement of the affected fuel pump splined couplings. We are proposing this AD to prevent failure of the engine and loss of the airplane.

This rule establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures 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, adding new obstacles, or changing 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.

We propose to adopt a new airworthiness directive (AD) for Diamond Aircraft Industries GmbH Model H-36, HK 36 R, HK 36 TS, and HK 36 TTS airplanes. 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 installation of an unsuitable self-locking nut on the bell crank of the elevator push rod that can cause failure of the elevator, resulting in loss of control. We are issuing this proposed AD to require actions to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation (Type Certificate previously held by Raytheon Aircraft Company; Beech Aircraft Corporation) Model 400A airplanes. This proposed AD was prompted by a report that the wiring for the 5-volt direct current (DC) system is undersized and does not have adequate circuit protection for the smaller gauge wire. This proposed AD would require installing an in-line fuse in the 5-volt DC system for each of the five instrument lighting control power supplies. We are proposing this AD to prevent failure of the wiring, which could result in smoke in the cockpit, loss of cockpit lighting, and potential damage to surrounding wiring for other cockpit equipment such as the stick shaker function or angle-of-attack indicators.

The FHWA, on behalf of Caltrans, is issuing this notice to announce actions taken by Caltrans that are final within the meaning of 23 U.S.C. 139(l)(1). The actions relate to a proposed highway project, State Route 91 from the cities of Anaheim and Yorba Linda to the City of Riverside, in the counties of Orange and Riverside, State of California. Those actions grant licenses, permits, and approvals for the project.

FHWA is informing the public of their intention to request the Office of Management and Budget's (OMB) approval for a new information collection, which is summarized below under SUPPLEMENTARY INFORMATION. We are required to publish this notice in the Federal Register by the Paperwork Reduction Act of 1995.

We propose to adopt a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ series airplanes. This proposed AD was prompted by a report that certain ceramic terminal blocks, through which the wiring for the engine fire extinguishers, fire detection circuits, and engine and intake anti-ice system are routed, have been found to have moisture ingress which can degrade the insulation resistance of the ceramic terminal blocks. This proposed AD would require a one-time insulation resistance test of ceramic terminal blocks, and if necessary, replacement of the blocks. We are proposing this AD to prevent latent failure of the number 2 fire bottle, which, in the event of an engine fire, could result in failure of the fire bottle to discharge when activated and possibly preventing the flightcrew from extinguishing an engine fire.

Through this Notice of Proposed Rulemaking (NPR), the Board is proposing a rule establishing additional disclosure requirements for notices and petitions for exemption where the underlying lease or line sale includes an interchange commitment.

By this notice, the FHWA is advising the public of final agency actions subject to 23 U.S.C. 139(l)(1). The actions relate to a proposed project to improve the Brent Spence Bridge over the Ohio River, as well as improvements to Interstate Routes 71 and 75 and interchanges in the City of Cincinnati, Hamilton County, State of Ohio and City of Covington, Kenton County, Commonwealth of Kentucky, including a new bridge over the Ohio River. This notice covers those Federal agency actions to grant licenses, permits, and approvals for the project.

This action amends Class E airspace at Boone, IA. Decommissioning of the Boone non-directional beacon (NDB) at Boone Municipal Airport has made reconfiguration necessary for standard instrument approach procedures and for the safety and management of Instrument Flight Rule (IFR) operations at the airport.

The FAA is issuing this notice to advise the public of the tenth meeting of the RTCA Special Committee 225, Rechargeable Lithium Battery and Battery SystemsSmall and Medium Size.

This notice provides information regarding the FHWA's finding that a Buy America waiver is appropriate for the use of non-domestic Technologie Alpine De Securite (TAS) Gazex[supreg] Avalanche Exploder in the State of Utah and TAS O'Bell Avalanche Initiating Blaster for the State of Wyoming.

FMCSA announces receipt of applications from 12 individuals for exemption from the prohibition against persons with insulin-treated diabetes mellitus (ITDM) operating commercial motor vehicles (CMVs) in interstate commerce. If granted, the exemptions would enable these individuals with ITDM to operate CMVs in interstate commerce.

FMCSA announces its decision to exempt 7 individuals from the vision requirement in the Federal Motor Carrier Safety Regulations (FMCSRs). They are unable to meet the vision requirement in one eye for various reasons. The exemptions will enable these individuals to operate commercial motor vehicles (CMVs) in interstate commerce without meeting the prescribed vision requirement in one eye. The Agency has concluded that granting these exemptions will provide a level of safety that is equivalent to or greater than the level of safety maintained without the exemptions for these CMV drivers.

We are adopting a new airworthiness directive (AD) for certain Airbus Model A320-214 and -232 airplanes. This AD was prompted by reports that medium-head fasteners were installed in lieu of shear-head fasteners on a certain upper panel, which manufacturer fatigue and damage tolerance analyses demonstrated could have an effect on panel fatigue life. This AD requires repetitive inspections for cracking of certain fasteners, and repairs if necessary. We are issuing this AD to detect and correct such cracking, which could result in the loss of structural integrity of the airplane.

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model MD-90-30 airplanes. This AD was prompted by reports of fatigue cracks found in Stringer 11 at the outboard flap, inboard drive hinge at Station Xrs=164.000. This AD requires repetitive inspections for cracks in Stringer 11, and a splice repair if necessary; and repetitive post-repair inspections, and repair if necessary. We are issuing this AD to detect and correct such cracking, which could result in the wing structure not supporting the limit load condition, which could lead to loss of the structural integrity of the wing.
