Federal Aviation Administration 2009 – Federal Register Recent Federal Regulation Documents

The FAA is adopting a new airworthiness directive (AD) for General Electric Company (GE) CF6-45 and CF6-50 series turbofan engines. This AD requires replacing certain forward and aft centerbodies of the long fixed core exhaust nozzle (LFCEN) assembly. This AD results from the engine manufacturer issuing new service information. We are issuing this AD to prevent the forward and aft centerbody of the LFCEN assembly from separating due to high imbalance engine conditions, leading to damage to 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:

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), which applies to certain Boeing Model 767 series airplanes. That AD currently requires a one-time inspection for missing, damaged, or incorrectly installed parts in the separation link assembly on the deployment bar of the emergency escape system on the entry or service door, and installation of new parts if necessary. This new AD requires replacing the separation link assembly on the applicable entry and service doors with an improved separation link assembly, and doing related investigative and corrective actions if necessary; and inspecting for discrepancies of the unloaded spring dimensions in the separation link assembly, and doing corrective actions if necessary. This AD also removes certain airplanes from the applicability. This AD results from reports that entry and service doors did not open fully during deployment of emergency escape slides, and additional reports of missing snap rings. We are issuing this AD to prevent failure of an entry or service door to open fully in the event of an emergency evacuation, which could impede exit from the airplane. This condition could result in injury to passengers or crewmembers.

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.

The FAA invites public comments about our intention to request the Office of Management and Budget's (OMB) revision of a current information collection. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on October 31, 2008, vol. 73, no. 212, page 65003. 14 CFR Part 298 requires air carrier operators to obtain a certificate of public convenience and necessity from the DOT, with the exception of air taxi and commuter air operators.

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.

The FAA is adopting a new airworthiness directive (AD) for General Electric Company (GE) CF6-80C2 and CF6-80E1 series turbofan engines with fuel manifolds part numbers (P/Ns) 1303M31G12 and 1303M32G12, installed in drainless fuel manifold assemblies (introduced by GE Aircraft Engines (GEAE) Service Bulletins (SB) CF6-80C2 S/B 73- 0253 and CF6-80E1 S/B 73-0026). This AD requires removing the loop clamps that hold the fuel manifold to the compressor rear frame (CRF) damper brackets, inspecting the fuel manifold for wear at each clamp location, and replacing the clamps with new, zero-time parts. This AD also requires revising the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness (ICA) and air carrier's Continuous Airworthiness Maintenance Programs (CAMP) to require repetitive fuel manifold inspection and loop clamp replacement. This AD results from reports of fuel leaks during engine operation. We are issuing this AD to prevent fuel leaks that could result in an under- cowl fire and damage to the airplane.

This action revises Class D and E airspace at King Salmon, AK, to provide adequate controlled airspace to contain aircraft executing Standard Instrument Approach Procedures (SIAPs). Nine SIAPs, and a textual Obstacle Departure Procedure (ODP) are being amended for the King Salmon Airport. This action revises Class D and E airspace upward from the surface, and from 700 feet (ft.) and 1,200 ft. above the surface at King Salmon Airport, King Salmon, AK.

This action amends Class E airspace at Medford, WI. Additional controlled airspace is necessary to accommodate Area Navigation (RNAV) Standard Instrument Approach Procedures (SIAP) at Taylor County Airport, Medford, WI. This action also makes a minor change to the geographical coordinates of Taylor County Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at Taylor County Airport.

This action amends Class E airspace at Columbus, OH. Additional controlled airspace is necessary to accommodate Area Navigation (RNAV) Standard Instrument Approach Procedures (SIAP) at Rickenbacker International Airport, Columbus, OH. This action also makes a minor change to the geographical coordinates of Bolton Field Airport, Columbus, OH. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at Rickenbacker International Airport.

This action amends Class E airspace at Milwaukee, WI. Additional controlled airspace is necessary to accommodate Area Navigation (RNAV) Standard Instrument Approach Procedures (SIAP) at Waukesha County Airport, Waukesha, WI. Also, this rule changes an airport name from John H. Batten Field to John H. Batten Airport, Racine, WI. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at Waukesha County Airport.

This action proposes to amend Class E airspace at Coleman, TX. Controlled airspace is necessary to accommodate Standard Instrument Approach Procedures (SIAPs) at Coleman Municipal Airport, Coleman, TX. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) aircraft operations at Coleman Municipal Airport.

We are adopting a new airworthiness directive (AD) for certain McDonnell Douglas airplanes listed above. This AD requires installing a dam assembly for the container of the fuel boost pump of the center tank located in the right main tank, and doing the related investigative actions, and corrective actions if necessary. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent the center tank fuel boost pump from operating in a fuel vapor zone and becoming a potential ignition source in the right main tank, potentially resulting 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) 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 rule 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 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:

We propose to adopt a new Airworthiness Directive (AD) for the products listed above that would supersede an existing AD. 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 is superseding an existing airworthiness directive (AD) for General Electric Company (GE) CF6-80A, CF6-80C2, and CF6-80E1 series turbofan engines. That AD required revisions to the Airworthiness Limitations Section (ALS) of the manufacturer's Instructions for Continued Airworthiness (ICA) to include required inspection of selected critical life-limited parts at each piece-part exposure. This AD requires revisions to the CF6-80A, CF6-80C2, and CF6- 80E1 series engines ALS sections of the manufacturer's manuals and an air carrier's approved continuous airworthiness maintenance program to incorporate additional inspection requirements, and to update certain Engine Manual Inspection Task and Sub Task Number references. This AD results from the need to require enhanced inspection of selected critical life-limited parts of CF6-80A, CF6-80C2, and CF6-80E1 series engines. We are issuing this AD to prevent critical life-limited rotating engine part failure, which could result in an uncontained engine failure and damage to the airplane.

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by the 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 revising an earlier proposed airworthiness directive (AD) for all Boeing Model 747 airplanes. The original NPRM would have required inspecting for cracks in the left- and right-side Stringer 11 longeron adjacent to the horizontal stabilizer pivot bulkhead, and related investigative and corrective actions if necessary. The original NPRM resulted from a report of a crack found in the right-side Stringer 11 longeron horizontal flange, adjacent to the horizontal stabilizer pivot bulkhead, during a routine maintenance inspection. This action revises the original NPRM by reducing the compliance times for certain airplanes. We are proposing this supplemental NPRM to detect and correct fatigue cracking of the longeron, which can propagate and cause damage to the adjacent horizontal stabilizer pivot bulkhead. This damage could result in loss of structural integrity and consequent inability of the bulkhead to carry flight loads, which could adversely affect controllability of the airplane.

The FAA proposes to adopt a new airworthiness directive (AD) for Hamilton Sundstrand Propellers model 247F propeller assemblies with certain part number (P/N) and serial number (SN) blades. This proposed AD would require removing affected propeller blades from service. This proposed AD results from reports of blades with corrosion pits in the tulip area of the blades. We are proposing this AD to prevent cracks from developing in the tulip area of the blade, which could result in separation of the blade and possible loss of airplane control.
