May 8, 2008 – Federal Register Recent Federal Regulation Documents

We are adopting a new airworthiness directive (AD) to supersede AD 2007-13-17, which applies to certain Air Tractor, Inc. (Air Tractor) Models AT-602, AT-802, and AT-802A airplanes. AD 2007-13- 17 currently requires you to repetitively inspect the engine mount for any cracks, repair or replace any cracked engine mount, and report any cracks found to the FAA. Since we issued AD 2007-13-17, Air Tractor has learned of a Model AT-502B with a crack located where the lower engine mount tube is welded to the engine mount ring. In addition, Air Tractor has developed gussets that, when installed according to their service letter, terminate the repetitive inspection requirement. Consequently, this AD would retain the inspection actions of AD 2007-13-17 for Model AT-602, AT-802, and AT-802A airplanes, including the compliance times and effective dates; establish new inspection actions for the AT-400 and AT-500 series airplanes; incorporate a mandatory terminating action for all airplanes; and terminate the reporting requirement of AD 2007- 13-17. We are issuing this AD to detect and correct cracks in the engine mount, which could result in failure of the engine mount. Such failure could lead to separation of the engine from the airplane.

We are adopting a new airworthiness directive (AD) for certain Boeing Model 737-600, -700, -700C, -800, and -900 series airplanes. This AD requires revising the Airworthiness Limitations (AWLs) section of the Instructions for Continued Airworthiness by incorporating new limitations for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. This AD also requires the initial inspection of a certain repetitive AWL inspection to phase in that inspection, and repair if necessary. This AD results from a design review of the fuel tank systems. We are issuing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

We are adopting a new airworthiness directive (AD) for certain Boeing Model 747-400, -400D, and -400F series airplanes. This AD requires revising the FAA-approved maintenance program by incorporating new airworthiness limitations (AWLs) for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. This AD also requires the initial inspection of certain repetitive AWL inspections to phase in those inspections, and repair if necessary. This AD results from a design review of the fuel tank systems. We are issuing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

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:

The FAA is superseding an existing airworthiness directive (AD) that applies to certain EMBRAER Model EMB-135 airplanes; and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. The existing AD currently requires performing repetitive inspections for cracks, ruptures, or bends in certain components of the elevator control system; replacing discrepant components; and, for certain airplanes, installing a new spring cartridge and implementing new logic for the electromechanical gust lock system. The existing AD also requires eventual modification of the elevator gust lock system to replace the mechanical system with an electromechanical system, which terminates the repetitive inspections. This AD reduces the compliance time for doing the modification. This AD results from additional reports of failure of the mechanical gust lock system to protect the elevator control surfaces and components from high wind gusts. We are issuing this AD to prevent discrepancies in the elevator control system, which could result in reduced control of the elevator and consequent reduced controllability of the airplane.

This action confirms the effective date of a direct final rule published in the Federal Register (73 FR 9183) that establishes Class E Airspace at Swans Island, ME to support a new Area Navigation (RNAV) Global Positioning System (GPS) Special Instrument Approach Procedure (IAP) that has been developed for medical flight operations into the Swans Island Heliport.

This amendment adopts a new airworthiness directive (AD) for the specified Sikorsky Aircraft Corporation (Sikorsky) model helicopters that requires installing an electric chip detector on each engine and an on-board chip detector annunciation system. The AD also requires revising the Rotorcraft Flight Manual (RFM) to add procedures for crew response to the illumination of an on-board chip detector warning light. This AD also requires testing the engine chip detector system at specified intervals. This amendment is prompted by reports of Number 5 engine bearing failures. Failure of the bearing resulted in erratic movement of the high-speed, engine-to-transmission shaft (shaft), an oil leak, an in-flight fire, and an emergency landing. The actions specified by this AD are intended to detect an impending bearing failure, which if undetected and not addressed by appropriate crew action may result in an oil leak, a severed shaft housing, an uncontained in-flight fire, and a subsequent emergency landing.

This interim rule lists communities where modification of the Base (1% annual-chance) Flood Elevations (BFEs) is appropriate because of new scientific or technical data. New flood insurance premium rates will be calculated from the modified BFEs for new buildings and their contents.

Comments are requested on the proposed Base (1 percent annual- chance) Flood Elevations (BFEs) and proposed BFE modifications for the communities listed in the table below. The purpose of this notice is to seek general information and comment regarding the proposed regulatory flood elevations for the reach described by the downstream and upstream locations in the table below. The BFEs and modified BFEs are a part of the floodplain management measures that the community is required either to adopt or show evidence of having in effect in order to qualify or remain qualified for participation in the National Flood Insurance Program (NFIP). In addition, these elevations, once finalized, will be used by insurance agents, and others to calculate appropriate flood insurance premium rates for new buildings and the contents in those buildings.

The Bureau of Industry and Security published a final rule in the Federal Register on April 18, 2008 (73 FR 21035), that amended the Export Administration Regulations (EAR) to make various technical corrections and clarifications to the EAR as a result of a systematic review of the CCL. The amendments in that final rule included a revision to the ``Unit'' paragraph in the List of Items Controlled section of Export Control Classification Number (ECCN) 9A004. However, because of an inadvertent formatting error in a rule published on March 18, 1999 (64 FR 13338), the ``Related Controls'' paragraph in that CCL entry appeared to be a part of the ``Unit'' paragraph. This resulted in the inadvertent removal of the ``Related Controls'' paragraph in the List of Items Controlled section of that ECCN entry when the ``Unit'' paragraph was revised with the publication of the April 18, 2008, rule. Today's rule corrects that inadvertent removal by adding the ``Related Controls'' paragraph back into that ECCN entry.

The Coast Guard will implement a safety zone during the Hatteras Boat Parade and Firework Display, a motor yacht parade to be held on the waters of the Trent River, New Bern, North Carolina. Vessel traffic in portions on the Trent River adjacent to New Bern, North Carolina, will be restricted during the fireworks display.

Our regulations describe when a Social Security Administration (SSA) employee will testify or provide records or other information in a legal proceeding to which we are not a party. The regulations also describe how you request testimony of an SSA employee. This final rule updates the address you should use to request testimony of an SSA employee.

The Coast Guard is establishing special local regulations to regulate recurring marine events in the Fifth Coast Guard District. These regulations apply to all permitted events listed in the table attached to the regulation, and include events such as regattas, and marine parades. These regulations reduce the Coast Guard's administrative workload and expedite public notification of events.

The Coast Guard is establishing special local regulations during the ``Westville Parade of Lights'', a marine parade to be held on the waters of the Delaware River and Big Timber Creek, Westville, NJ. These special local regulations are necessary to provide for the safety of life on navigable waters during the event. This action is intended to restrict vessel traffic in a small portion of the Delaware River and Big Timber Creek during the event.

We propose to adopt a new airworthiness directive (AD) for certain Boeing Model 707 airplanes, and Model 720 and 720B series airplanes. This proposed AD would require repetitive detailed inspections to detect cracks and corrosion on any existing repairs and at certain body stations of the visible surfaces of the wing to body terminal fittings including the web, flanges, and ribs; and applicable related investigative and corrective actions. This proposed AD results from reports of cracks found in the wing to body terminal fittings during routine inspections. We are proposing this AD to prevent cracks and corrosion in the body terminal fittings, which could cause loss of support for the wing and could adversely affect the structural integrity of the airplane.

This action proposes to establish Class E airspace at Fort Collins-Loveland Municipal Airport, Fort Collins, CO. Additional controlled airspace is necessary to accommodate instrument flight rules (IFR) operations from this airport located in mountainous terrain and enable positive control at Fort Collins-Loveland Municipal Airport, Fort Collins, CO. The FAA is proposing this action to enhance the safety and management of aircraft operations at Fort Collins-Loveland Municipal Airport, Fort Collins, CO.

In this document, the Commission seeks comment on whether to assign Educational Broadband Service (EBS) spectrum in the Gulf of Mexico. It also seeks comment on how to license unassigned and available EBS spectrum. Specifically, we seek comment on whether it would be in the public interest to develop a scheme for licensing unassigned EBS spectrum that avoids mutual exclusivity; we ask whether EBS eligible entities could participate fully in a spectrum auction; we seek comment on the use of small business size standards and bidding credits for EBS if we adopt a licensing scheme that could result in mutually exclusive applications; we seek comment on the proper market size and size of spectrum blocks for new EBS licenses; and we seek comment on issuing one license to a State agency designated by the Governor to be the spectrum manager, using frequency coordinators to avoid mutually exclusive EBS applications, as well as other alternative licensing schemes. The Commission must develop a new licensing scheme for EBS in order to achieve the Commission's goal of facilitating the development of new and innovative wireless services for the benefit of students throughout the nation.

EPA is proposing to approve State Implementation Plans (SIPs) submitted by the States of South Dakota and Wyoming that address interstate transport with respect to the 1997 8-hour ozone and fine particulate matter (PM2.5) National Ambient Air Quality Standards. EPA has determined that the Interstate Transport declarations submitted by South Dakota on May 15, 2007, and by Wyoming on May 3, 2007, satisfy the requirements of the Clean Air Act section 110(a)(2)(D)(i) provisions, also known as the ``good neighbor'' provisions, that a state SIP contain adequate provisions prohibiting air pollutant emissions from sources or activities in the state from adversely affecting another state. This action is being taken under section 110 of the Clean Air Act. In the ``Rules and Regulations'' section of this Federal Register, EPA is approving the States' SIP revisions as a direct final rule without prior proposal because the Agency views these as non- controversial SIP revisions and anticipates no adverse comments. A detailed rationale for the approval is set forth in the preamble to the direct final rule. If EPA receives no adverse comments, EPA will not take further action on this proposed rule. If EPA receives adverse comments, EPA will withdraw the direct final rule and it will not take effect. EPA will address all public comments in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period on this action. Any parties interested in commenting must do so at this time. Please note that if EPA receives adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment.
