May 28, 2009 – Federal Register Recent Federal Regulation Documents

These special conditions are issued for the Embraer S.A. Model EMB-505 airplane. This airplane will have a novel or unusual design feature(s) associated with the use of an electronic engine control system instead of a traditional mechanical control system. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

This action proposes to establish Class E airspace at Quinhagak, AK. Two Standard Instrument Approach Procedures (SIAPs) are being developed for the Quinhagak Airport at Quinhagak, AK. Additionally, one textual Obstacle Departure Procedure (ODP) is being developed. Adoption of this proposal would result in creating Class E airspace upward from 700 feet (ft.) above the surface at the Quinhagak Airport, Quinhagak, AK.

The Federal Energy Regulatory Commission (Commission) adopts reporting requirements under the expanded blanket authorization established in Order No. 708-A, which amends section 33.1(c)(12) of the Commission's regulations.

Pursuant to section 215 of the Federal Power Act (FPA), the Federal Energy Regulatory Commission (Commission) approves regional Reliability Standard BAL-004-WECC-01 (Automatic Time Error Correction), as submitted by the North American Electric Reliability Corporation. As a separate action, pursuant to section 215(d)(5) of the FPA, the Commission directs the Western Electricity Coordinating Council to develop several modifications to the regional Reliability Standard. The regional Reliability Standard requires balancing authorities within the Western Interconnection to maintain interconnection frequency within a predefined frequency profile and ensure that time error corrections are effectively conducted in a manner that does not adversely affect the reliability of the Interconnection.

Pursuant to section 215 of the Federal Power Act, the Federal Energy Regulatory Commission hereby approves the North American Electric Reliability Corporation's (NERC) interpretation of one Commission- approved Reliability Standard, BAL-003-0, Frequency Response and Bias; and remands NERC's proposed interpretation of VAR-001-1, Voltage and Reactive Control, for reconsideration consistent with this Final Rule.

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 Eurocopter Deutschland GmbH (Eurocopter) Model EC135 helicopters. This AD results from a report of abnormal main rotor blade vibrations on a Eurocopter Model EC135 helicopter. This AD also results from mandatory continuing airworthiness information (MCAI) issued by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community. The MCAI states that an operator reported unusual vibrations during the start phase of the main rotor blade on one helicopter. The vibrations stopped after the application of torque. Subsequent maintenance personnel found that six of the eight attachment screws of the lower hub-shaft bearing support were loose. This condition was discovered in two additional helicopters. Loose screws in the bearing support, if not detected and corrected, could result in abnormal main rotor blade vibrations and subsequent damage to the main transmission.

This 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 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) to supersede AD 2008-12-16, which applies to certain M7 Aerospace LP SA226 and SA227 series airplanes. AD 2008-12-16 currently requires you to inspect wires and tube assemblies for chafing, arcing, or insufficient clearance between components. If chafing, arcing, or insufficient clearance between components is found, AD 2008-12-16 requires you to clear, repair, and/or replace all chafed wires, components, and tube assemblies. AD 2008-12-16 also requires you to cover the four-gauge wires leaving the battery box with firesleeving and secure them with a clamp. Since we issued AD 2008-12-16, M7 Aerospace LP has notified us that Model SA227-BC (C-26A) was inadvertently left out of the Applicability section of the AD, and they updated some of the service information due to parts availability. Operators have also identified issues with model applicability that needed clarification. Consequently, this AD retains the actions of AD 2008-12-16, adds Model SA227-BC (C-26A) to the Applicability section, and regroups the models for clarification. We are issuing this AD to detect and correct chafing of electrical wires, components, and tube assemblies. This condition could result in arcing of exposed wires with consequent burning of a hole in a hydraulic line or the bleed air line. This failure could lead to a hydraulic fluid leak and a possible fire in the engine nacelle compartment.

The Department of the Treasury's Office of Foreign Assets Control (``OFAC'') is adding a new part to the Code of Federal Regulations to implement Executive Order 13400 of April 26, 2006, ``Blocking Property of Persons in Connection With the Conflict in Sudan's Darfur Region.''
