Airworthiness Directives; Air Tractor, Inc. Models AT-400, AT-401, AT-401B, AT-402, AT-402A, and AT-402B Airplanes
We are adopting a new airworthiness directive (AD) to revise AD 2006-08-08, which applies to certain Air Tractor, Inc. (Air Tractor) Models AT-400, AT-401, AT-401B, AT-402, AT-402A, and AT-402B airplanes. AD 2006-08-08 currently requires you to repetitively eddy current inspect the wing lower spar cap in order to reach the safe life and, for certain Models AT-402A and AT-402B airplanes and those that incorporate or have incorporated Marburger Enterprises, Inc. (Marburger) winglets, lowers the safe life for the wing lower spar cap. Since we issued AD 2006-08-08, we have received information to update inspection intervals for the Models AT-401B, AT-402A, and AT-402B airplanes based on a revised damage tolerance analysis. Consequently, this AD would not only retain the actions of AD 2006-08-08, but would reduce the number of repetitive inspections for all affected Model AT- 401B airplanes and certain Models AT-402A and AT-402B airplanes. We are issuing this AD to prevent fatigue cracks from occurring in the wing lower spar cap before the originally established safe life is reached. Fatigue cracks in the wing lower spar cap, if not detected and corrected, could result in wing separation and loss of control of the airplane.
Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments
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.
International Standards on the Transport of Dangerous Goods; Public Meeting
This notice is to advise interested persons that PHMSA will conduct a public meeting in preparation for the 35th session of the United Nations Sub-Committee of Experts on the Transport of Dangerous Goods (UNSCOE TDG) to be held June 22-26, 2009 in Geneva, Switzerland. During this meeting, PHMSA is also soliciting comments relative to potential new work items which may be considered for inclusion in its international agenda, and comments relative to a potential future rulemaking action regarding the use and applicability of international standards.
Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments
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.

Airworthiness Directives; McDonnell Douglas Model 717-200 Airplanes
We are adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model 717-200 airplanes. This AD requires modifying the wire installation of the auxiliary hydraulic pump in the right wheel well of the main landing gear (MLG). This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent a tire burst when the MLG is in the retracted position from causing damage to the wire assembly of the auxiliary hydraulic pump and subsequent electrical arcing, creating the potential of an ignition source to the center wing tank, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; Piper Aircraft, Inc. Models PA-46-350P and PA-46R-350T Airplanes
We are adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc. Models PA-46-350P and PA-46R-350T airplanes. This AD requires you to inspect the 35-amp and 250-amp current limiters to verify they are installed in the proper locations and correct the installation if the current limiters are not installed in the proper locations. This AD also limits operation to ``only under day visual flight rules (VFR)'' until the current limiter installation is inspected and corrected. This AD results from three reports of incorrectly installed current limiters. We are issuing this AD to detect and correct incorrect installation of 35-amp and 250-amp current limiters, which could result in failure of the 35-amp current limiter if installed in the 250-amp location. This failure could lead to a total loss of electrical power.
Environmental Impact Statement: St. Clair County, MI
This notice announces the availability of a Final Environmental Impact Statement (FEIS) and Section 4(f) Evaluation for the Blue Water Bridge Plaza Study (BWB). This action is pursuant to the National Environmental Policy Act (NEPA) of 1969, 42 U.S.C. 4321 et seq., as amended and the Council on Environmental Quality Regulations (40 CFR Parts 1500-1508). The FEIS discusses the recommended alternative to improve the United States inspection Facility at the Blue Water Bridge Plaza and the I-94/I-69 corridor in St. Clair County, Michigan; describes the environmental impacts of the proposed project
Airworthiness Directives; ATR Model ATR72 Airplanes
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:
Airworthiness Directives; McDonnell Douglas Model MD-90-30 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model MD-90-30 airplanes. This AD requires modifying the auxiliary hydraulic power system (including doing all applicable related investigative and corrective actions). This AD results from fuel system reviews conducted by the manufacturer, as well as reports of shorted wires in the right wheel well and evidence of arcing on the power cables of the auxiliary hydraulic pump. We are issuing this AD to prevent shorted wires or electrical arcing at the auxiliary hydraulic pump, which could result in a fire in the wheel well; and to reduce the potential of an ignition source adjacent to the fuel tanks, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; Pratt & Whitney (PW) JT9D-7 Series Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for PW models JT9D-7, -7A, -7AH, -7H, -7F, and -7J turbofan engines. This AD requires initial and repetitive borescope inspections of the 2nd stage high-pressure turbine (HPT) rotor and stator assembly. This AD results from an uncontained failure of a 2nd stage HPT rotor disk that caused the engine to separate from the airplane. We are issuing this AD to prevent failure of the 2nd stage HPT rotor disk, which could result in uncontained engine failure, damage to the airplane, and the engine separating from the airplane.
Filing Requirements of 49 U.S.C. 14123; The Motor Carrier Financial and Operating Statistics Program (the Annual Form M Filing); Application for Exemption From Swift Transportation Corporation
The Federal Motor Carrier Safety Administration (FMCSA) published a Federal Register notice of an application by Swift Transportation Corporation (Swift Transportation) for an exemption from the requirement annually to report certain financial information (49 CFR 369.1). Swift Transportation stated that disclosing this information would cause competitive harm. The Agency received one comment to the public docket. The Agency has considered the comment and grants Swift Transportation's request for exemption.
