Airworthiness Directives; Cirrus Design Corporation Model SR22 Airplanes

Thu, Nov 29 2007 11:00:00 GMT

The FAA is adopting a new airworthiness directive (AD) for certain Cirrus Design Corporation (Cirrus) Model SR22 airplanes. This AD requires you to install a drain hole in the left and right outboard wing tips. This AD results from reports of pilots' inability to move the aileron control without using excessive force when flying in freezing conditions. Moisture from a prior rain shower entered through a gap at the interface of the left and right outboard wing tips and wing structure. The moisture traveled along the aft wing shear web, accumulated below the aileron control pulley, and froze at an altitude with an outside air temperature below freezing. When this moisture is exposed to freezing conditions, operation of the aileron control pulley is impaired. We are issuing this AD to prevent moisture from accumulating along the wing shear web where it may freeze in certain conditions. This condition could result in operational failure of the aileron control pulley, which could lead to loss of con

Airworthiness Directives; GROB-WERKE GMBH & CO KG Models G102 CLUB ASTIR III, G102 CLUB ASTIR IIIb, and G102 STANDARD

Thu, Nov 29 2007 11:00:00 GMT

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

GROB received isolated difficulty reports regarding cracks on welded parts of the flight control system of the type G102, model CLUB ASTIR III & IIIb, and STANDARD ASTIR III. The cracks progress slowly from the welding seams periphery, and may eventually result in rupture at a matured stage.

We are issuing this AD to require actions to correct the unsafe condition on these products.

Airworthiness Directives; Hartzell Propeller Inc. Model HC-E5N-3( ), HC-E5N-3( )(L), and HC-E5B-5( ) Propellers

Thu, Nov 29 2007 11:00:00 GMT

The FAA is adopting a new airworthiness directive (AD) for Hartzell Propeller Inc. Model HCE5N3( ), HCE5N3( )(L), and HCE5B 5( ) propellers. This AD requires a onetime eddy current inspection of the propeller hub mounting bolt holes and replacement of the propeller hub if cracked. This AD results from the discovery of a fivebladed propeller hub with a large crack on the mounting flange of the hub. We are issuing this AD to prevent propeller hub failure, blade separation, damage to the airplane, and possible loss of airplane control.

Information Collection Available for Public Comments and Recommendations

Thu, Nov 29 2007 11:00:00 GMT

In accordance with the Paperwork Reduction Act of 1995, this notice announces the Maritime Administration's (MARAD's) intention to request extension of approval for three years of a currently approved information collection.

Airworthiness Directives; Rolls-Royce plc, RB211 Trent 768-60, 772-60, and 772B-60 Turbofan Engines

Thu, Nov 29 2007 11:00:00 GMT

The FAA is superseding an existing airworthiness directive (AD) for RollsRoyce plc (RR) RB211 Trent 76860, 77260, and 772B60 turbofan engines. That AD currently requires initial and repetitive on wing or inshop inspections of the high pressure/intermediate pressure (HP/IP) turbine bearing oil feed tube heat shield. This AD requires the same actions but introduces a terminating action to the repetitive inspections. This AD results from RR introducing a revised HP/IP turbine bearing support structure as terminating action to the repetitive inspections of the HP/IP turbine bearing oil feed tube heat shield. We are issuing this AD to prevent an uncontained failure of the HP turbine disc and damage to the airplane.

Airworthiness Directives; Turbomeca Arriel 2S1 and 2S2 Turboshaft Engines

Thu, Nov 29 2007 11:00:00 GMT

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing [[Page 67563]]
airworthiness information (MCAI) provided by the European Aviation Safety Agency (EASA) to identify and correct an unsafe condition on Turbomeca Arriel 2S1 and 2S2 turboshaft engines. The MCAI states the following:

During assembly of a new HP/LP fuel pump, the drain screw on the fuel filter unit failed when it was tightened to the torque value specified in the assembly schedule (12 Nm). Investigation of the screw showed that it was fully conformed to its specification, in terms of both dimensions and material. The mechanical calculations show, however, that a torque value of 12 Nm is too high for this screw, exceeding the elastic limit of the material. Failure of the affected screw could cause a fuel leak, resulting in an engine flameout or engine fire.
We are issuing this AD to prevent a fuel leak as a result of a ruptured fuel filter drain screw that co

IFR Altitudes; Miscellaneous Amendments

Thu, Nov 29 2007 11:00:00 GMT

This amendment adopts miscellaneous amendments to the required IFR (instrument flight rules) altitudes and changeover points for certain Federal airways, jet routes, or direct routes for which a minimum or maximum en route authorized IFR altitude is prescribed. This regulatory action is needed because of changes occurring in the National Airspace System. These changes are designed to provide for the safe and efficient use of the navigable airspace under instrument conditions in the affected areas.

Proposed Modification of Class E Airspace; Hollister, CA

Thu, Nov 29 2007 11:00:00 GMT

This action proposes to modify the Class E airspace area at Hollister, CA. Establishment of an Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP) at Hollister Municipal Airport, Hollister, CA, has made this proposal necessary. Additional controlled airspace is needed for the safety and management of aircraft executing the new RNAV (GPS) SIAPs at Hollister Municipal Airport, Hollister, CA.

Proposed Establishment of Low Altitude Area Navigation Routes (T- Routes); St. Louis, MO

Thu, Nov 29 2007 11:00:00 GMT

This action proposes to establish two low altitude Area Navigation (RNAV) routes, designated T251 and T272, in the St. Louis, MO, terminal area. Troutes are low altitude Air Traffic Service routes, based on RNAV, for use by aircraft that have instrument flight rules (IFR) approved Global Positioning System (GPS)/Global Navigation Satellite System (GNSS) equipment. The FAA is proposing this action to enhance safety and improve the efficient use of the navigable airspace in the St. Louis, MO, terminal area.

Noise Compatibility Program Notice Baton Rouge Metropolitan Airport, Ryan Field, Baton Rouge, LA

Thu, Nov 29 2007 11:00:00 GMT

The Federal Aviation Administration (FAA) announces its findings on the noise compatibility program submitted by the Greater Baton Rouge Airport District under the provisions of 49 U.S.C. (the Aviation Safety and Noise Abatement Act, hereinafter referred to as ``the Act'') and 14 CFR part 150. These findings are made in recognition of the description of Federal and nonfederal
responsibilities in Senate Report No. 9652 (1980). On July 30, 2007, the FAA determined that the noise exposure maps submitted by the Greater Baton Rouge Airport District under part 150 were in compliance with applicable requirements. On November 13, 2007, the FAA approved the Baton Rouge Metropolitan Airport, Ryan Field noise compatibility program. Most of the recommendations of the program were approved. No program elements relating to new or revised flight procedures for noise abatement were proposed by the airport operator.

Canadian National Railway Company and Grand Trunk Corporation-- Control--EJ&E West Company \1\

Thu, Nov 29 2007 11:00:00 GMT

The Surface Transportation Board (Board) is accepting for consideration the primary application filed October 30, 2007, by Canadian National Railway Corporation (CNR) and Grand Trunk Corporation (GTC), a noncarrier holding company through which CNR controls its U.S. rail subsidiaries, and seven related filings. The primary application seeks Board approval under 49 U.S.C. 1132126 of the acquisition of control of EJ&E West Company (EJ&EW), a wholly owned noncarrier subsidiary of Elgin, Joliet and Eastern Railway Company (EJ&E), by CNR and GTC. This proposal is referred to as the Control Transaction, and CNR and GTC are referred to collectively as applicants.

The related filings are notices of exemption involving an intra corporate family transaction and the granting of trackage rights. The SubNo. 1 filing provides for EJ&E to transfer property to EJ&EW, which, at that time, would become a rail common carrier, prior to applicants acquiring control of EJ&EW. The SubNos. 2 through 7 filings provi
