Federal Aviation Administration 2007 – Federal Register Recent Federal Regulation Documents

We propose to adopt a new airworthiness directive (AD) for the products listed above. 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:

The FAA adopts a new airworthiness directive (AD) for all Glasflugel Models H 301 ``Libelle,'' H 301B ``Libelle,'' Standard ``Libelle,'' and Standard Libelle-201B sailplanes. This AD requires you to replace the rudder actuator arm (manufactured according to drawing No. 301-45-10) with an improved design rudder actuator arm (manufactured following drawing No. 301-45-13). This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to detect and correct damage to the rudder actuator arm, which could result in failure of the rudder actuator arm. This failure could result in reduced or loss of rudder control.

This technical amendment corrects a final rule published in the Federal Register on August 1, 2006 (71 FR 43357), Docket No. FAA- 2006-24003, Airspace Docket No. 06-AAL-12. In that rule, the reference to FAA Order 7400.9 was published as FAA Order 7400.9N. The correct reference is FAA Order 7400.9P. Also, the corresponding dates that refer to the Order should state ``* * * September 1, 2006, and effective September 15, 2006 * * *'' instead of ``* * * September 1, 2005, and effective September 15, 2005''. This technical amendment corrects those errors.

This technical amendment corrects a final rule published in the Federal Register on July 17, 2006 (71 FR 40394), Docket No. FAA- 2006-24813, Airspace Docket No. 06-AAL-16. In that rule, the reference to FAA Order 7400.9 was published as FAA Order 7400.9N. The correct reference is FAA Order 7400.9P. Also, the corresponding dates that refer to the Order should state `` * * * September 1, 2006, and effective September 15, 2006 * * *'' instead of `` * * * September 1, 2005, and effective September 15, 2005''. This technical amendment corrects those errors.

This amendment establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and/or Weather Takeoff Minimums 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, addition of new obstacles, or changes in 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.

The Federal Aviation Administration (FAA) announces that it is reviewing a proposed noise compatibility program that was submitted for Laredo International Airport under the provisions of 49 U.S.C. 47501 et seq. (the Aviation Safety and Noise Abatement Act, hereinafter referred to as ``the Act'') and 14 CFR part 150 by the city of Laredo, Texas. This program was submitted subsequent to a determination by FAA that associated noise exposure maps submitted under 14 CFR Part 150 for Laredo International Airport were in compliance with applicable requirements, effective September 22, 2005, and announced in the Federal Register/Vol. 70, Nos. 189/Friday, September 30, 2005. The proposed noise compatibility program will be approved or disapproved on or before August 27, 2007.

The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 206: Aeronautical Information Services Data Link.

This technical amendment corrects a final rule published in the Federal Register on June 19, 2006 (71 FR 35151), Docket No. FAA- 2006-24004, Airspace Docket No. 06-AAL-13. In that rule, the reference to FAA Order 7400.9 was published as FAA Order 7400.9N. The correct reference is FAA Order 7400.9P. Also, the corresponding dates that refer to the Order should state ``* * *September 1, 2006, and effective September 15, 2006* * *'', instead of ``* * *September 1, 2005, and effective September 15, 2005''. This technical amendment corrects those errors.

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:

This action supersedes emergency airworthiness directive (AD) 2007-04-51 that was sent previously to all known U.S. owners and operators of GE CF34-3A1/-3B/-3B1 turbofan engines. That action required a onetime visual and tactile inspection of certain areas of certain serial number (SN) fan disks for an arc-out defect, within 20 engine flight hours after the effective date of that AD. This AD supersedes AD 2007-04-51 and adds eight SNs to the list of suspect fan disks. This AD results from GE discovering eight additional SNs of fan disks suspected of having an arc-out defect, and from the original report that a GE CF34-3B1 turbofan engine experienced an uncontained fan disk failure during flight operation. We are issuing this AD to prevent an uncontained fan disk failure and airplane damage.

Under the provisions of Title 49, U.S.C., Section 47153(c), notice is being given that the FAA is considering a request from the City of Laurinburg and Town of Maxton to waive the requirement that approximately 0.807 acres of airport property, located at the Laurinburg-Maxton Airport, be used for aeronautical purposes.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 747-100, 747-100B, 747-200B, 747-200C, 747- 200F, 747-300, 747SR, and 747SP series airplanes. This proposed AD would require repetitive high frequency eddy current inspections for cracks of the fuselage skin at stringer 5 left and right between stations 340 and 350, and corrective actions if necessary. This proposed AD results from reports of fatigue cracks in the fuselage skin near stringer 5 between stations 340 and 350. We are proposing this AD to detect and correct fatigue cracking of the fuselage skin near stringer 5. Cracks in this area could join together and result in in- flight depressurization of the airplane.

This amendment removes an obsolete reference in Special Federal Aviation Regulation 50-2, Special Flight Rules in the Vicinity of Grand Canyon National Park, AZ. In section 9 of that SFAR, there is a ``Note'' that refers to an informational map of the Special Flight Rules Area (SFRA). This map is no longer available; however, there is an illustrational map of the SFRA in Part 93, Subpart U. Therefore, this technical amendment deletes the reference in SFAR 50-2, which is no longer needed and is confusing to the public.

This amendment amends Standard Instrument Approach Procedures (SIAPs) for operations at certain airports. These regulatory actions are needed because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, addition of new obstacles, or changes in 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.

The FAA is superseding two existing airworthiness directives (ADs), that apply to certain Bombardier Model CL-600-2B16 (CL-604) airplanes and Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. These models may be referred to by their marketing designations as RJ100, RJ200, RJ440, CRJ100, CRJ200, CRJ440, and CL-65. One existing AD requires replacing the horizontal stabilizer trim control unit (HSTCU) with a new HSTCU. The other existing AD requires revising the airplane flight manual (AFM) to advise the flightcrew of procedures to follow in the event of stabilizer trim runaway, and in the event of MACH TRIM, STAB TRIM, and horizontal stabilizer trim malfunctions; and revising the AFM to require a review of the location of certain circuit breakers. That AD also requires doing a functional check of the stabilizer trim system and installing circuit breaker identification collars, and provides an optional terminating action. This new AD requires the previously optional terminating action and requires further revisions to the AFM. This AD also requires the removal of certain AFM revisions. This AD results from reports of trim problems including uncommanded trim, trim in the opposite direction to that selected, loss of trim position indication and, in one case, potential loss of trim disconnect capability. We are issuing this AD to prevent these events, which could result in conditions that vary from reduced controllability of the airplane to loss of control of the airplane.

The FAA adopts a new airworthiness directive (AD) for certain Mooney Airplane Company, Inc., Models M20M and M20R airplanes. This AD requires you to remove the upper left and upper right engine mount attaching hardware, cut out and remove the upholstery and insulation between the fuselage tubular frame and the firewall, and replace the upper left and upper right engine mount attaching hardware with the new parts kit. This AD results from failure of the engine mount attaching hardware to maintain torque as a result of firewall insulation and upholstery being compressed between the fuselage tubular frame and the firewall at the upper left and upper right engine mount attach points. We are issuing this AD to prevent the upper right and upper left engine mounting hardware from losing torque, which could result in a reduction in engine mount load carrying capability and could lead to engine mount failure.

The FAA is adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model 717-200 airplanes. This AD requires replacing certain attaching hardware of the bulkhead nipple assemblies of the left and right wing vent boxes with new electrical bonding attaching hardware, doing resistance testing of the new electrical bonds, and doing fuel leakage testing of the reworked nipple assemblies. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to provide a conductive path, from the bulkhead nipple assemblies of the left and right wing vent boxes to the airframe structure inside the wing fuel tanks, to dissipate high- amperage lightning-induced currents, which might otherwise create an ignition source for fuel vapors inside the wing vent boxes and lead to an explosion of the fuel tanks.

The FAA is adopting a new airworthiness directive (AD) for GE CF6-80C2 series turbofan engines. This AD requires replacing certain installed part number (P/N) and serial number (SN) cast titanium weld- repaired forward engine mount platforms and cast titanium forward mount yokes, with a forged titanium or a non-welded cast titanium part. This AD results from the discovery of cracks, in a weld-repaired area on a forward engine mount platform and a forward engine mount yoke, found during a fluorescent penetrant inspection (FPI). These parts were weld- repaired during manufacture. We are issuing this AD to prevent cracks in the forward engine mount platform and forward engine mount yoke that could result in possible separation of the engine from the airplane.

This action proposes special conditions for the Dassault Aviation Model Falcon 7X airplane. This airplane will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. These design features include engine size and torque load, which affect sudden engine stoppage; electrical and electronic systems which perform critical functions, which affect operation without normal electrical power; and dive speed definition with speed protection system. These proposed special conditions pertain to their effects on the structural performance of the airplane. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for these design features. These proposed 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.

The FAA is adopting a new airworthiness directive (AD) for all EMBRAER Model ERJ 170 and ERJ 190 airplanes. This AD requires repetitive detailed inspections for blockage of the pitot drain holes of certain air data smart probes (ADSPs), removing accumulated moisture from the pneumatic passages of the ADSPs, related investigative actions, and corrective actions if necessary. This AD results from reports of erroneous air speed indications caused by blockage of the pitot sensors due to freezing of accumulated moisture in the ADSP pneumatic passages. We are issuing this AD to prevent an erroneous air speed indication, which could reduce the flightcrew's ability to control the airplane.

This document confirms the effective date of the direct final rule which revises Class E airspace at Thedford, NE.

This notice announces a public meeting of the FAA's Aviation Rulemaking Advisory Committee (ARAC) to discuss transport airplane and engine (TAE) issues.

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed 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:
