Federal Aviation Administration February 2009 – Federal Register Recent Federal Regulation Documents

We are adopting a new airworthiness directive (AD) to supersede AD 2008-06-28 R1, which applies to certain Avidyne Corporation (Avidyne) Primary Flight Displays (PFDs) (part numbers (P/Ns) 700-00006-000, -001, -002, -003, and -100) that are installed on airplanes. AD 2008-06-28 R1 currently requires you to do a check of the maintenance records and inspection of the PFD (if necessary) to determine if an affected serial number PFD is installed and incorporate (if necessary) operational limitations. Since we issued AD 2008-06-28 R1, Avidyne developed a factory modification that will correct the problems on these Avidyne PFDs and also factory modified certain serial number PFDs. To terminate the operational limitations of AD 2008-06-28 R1, this AD adds actions to assure any affected serial number PFD complies with one of the following: Passes the air data system performance verification test, receives the factory modification, or is replaced with a PFD that has complied with one of the previous two conditions or is not one of the affected serial number PFDs. Consequently, this AD will retain the actions from the previous AD until the added terminating action has been complied with. We are issuing this AD to prevent certain conditions from existing when PFDs display incorrect attitude, altitude, and airspeed information. This could result in airspeed/altitude mismanagement or spatial disorientation of the pilot with consequent loss of airplane control, inadequate traffic separation, or controlled flight into terrain.

We are adopting a new airworthiness directive (AD) for certain Boeing Model 727 airplanes. This AD requires among other actions, installing new ground fault interrupter (GFI) relays for the main fuel tanks and the auxiliary fuel tank pumps. This AD also requires revising the FAA-approved maintenance program to incorporate new Airworthiness Limitations for the GFI of the boost pumps and for the uncommanded on system for the auxiliary fuel tank pumps. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent an electrical fault in the fuel pump system, which might cause a connector or end cap to burn through and a subsequent fire or explosion inside the fuel pump or wing spar area. We are also issuing this AD to prevent uncommanded operation of the auxiliary fuel tank pumps, which can cause them to run dry. This condition will increase pump temperature and could supply an ignition source to fumes in the fuel tank, which can result in a consequent fire or explosion.

The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model CL-215-6B11 (CL-215T variant) and CL-215-6B11 (CL-415 variant) airplanes. This AD requires repetitive inspections for contamination of grease, bearing wear checks, grease applications of the rudder lower torque tube upper bearing, and a rudder upper hinge gap check; and related investigative and corrective actions if necessary. This AD results from a report of corrosion on the rudder lower torque tube upper bearing. We are issuing this AD to detect and correct corroded bearings which could lead to hinge deformation, and could result in a rudder jam and consequent reduced controllability of the airplane.

This action amends Class E Airspace at Roanoke Rapids, NC, to accommodate Standard Instrument Approach Procedures (SIAPs) at Halifax County Airport. The controlled airspace previously associated with this airport was removed in anticipation of the airport's scheduled closure. The closure of Halifax County Airport has been delayed because the opening of its replacement, Halifax-Northampton Regional Airport, has been delayed. Controlled airspace is necessary for the safety and management of SIAPs and for Instrument Flight Rule (IFR) operations to the airport.

This action amends the legal descriptions for Anderson AFB, and the Guam and Saipan International Airports. The Guam Air Route Traffic Control Center personnel conducted a review of their airspace and determined that current airspace descriptions needed to be updated. These are editorial revisions to reflect name changes and to update coordinates of the facilities. The changes will not affect the current area boundaries, altitudes, or the times of designation.

The FAA is superseding an existing airworthiness directive (AD) that applies to certain British Aerospace (Jetstream) Model 4100 series airplanes. The existing AD currently requires an eddy current conductivity test to measure the conductivity of the upper splice plate of the wing, and related investigative and corrective actions if necessary. This AD revises the applicability to include additional airplanes. This AD results from reports of exfoliation corrosion of the upper splice plate of the wing. We are issuing this AD to detect and correct such corrosion, which could result in reduced structural integrity of the airplane.

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD requires repetitive internal eddy current and detailed inspections to detect cracked stringer tie clips; measuring the fastener spacing and the edge margin if applicable, and doing applicable corrective and related investigative actions. As a temporary alternative to doing the actions described previously, this AD requires repetitive external general visual inspections of the skin and lap joints and repetitive external eddy current sliding probe inspections, as applicable, of the lap joints for cracks and evidence of overload resulting from cracked stringer tie clips, and applicable corrective actions if necessary. This AD results from a report of several cracked stringer tie clips. We are issuing this AD to detect and correct multiple adjacent cracked stringer tie clips and damaged skin and frames, which could lead to the skin and frame structure developing cracks and consequent decompression of the airplane.

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:
