Federal Aviation Administration 2007 – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747SR, and 747SP series airplanes. This proposed AD would require repetitive inspections for cracking of the station (STA) 1241 bulkhead fittings just above the canted pressure deck; a one-time determination of the edge margin at seven fastener positions on each side of the airplane; and related investigative/ corrective actions if necessary. This proposed AD results from a report that an operator found a 1.65-inch crack on the STA 1241 bulkhead fitting on the left side of a Boeing Model 747-200F series airplane that had accumulated 17,332 total flight cycles. We are proposing this AD to detect and correct cracking in the STA 1241 bulkhead fittings, which could result in reduced structural integrity of the airplane.

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: To prevent the cockpit door windows separating from their frames, * * * The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.

The FAA invites public comments about our intention to request the Office of Management and Budget (OMB) to approve a new information collection. This project involves collecting data from individual applicants who have recently taken, for the first time, and passed an oral and/or practical Airframe and/or Powerplant (A and/or P) Mechanic Certification test.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 737-600, -700, -700C, -800, and -900 series airplanes. This proposed AD would require revising the Airworthiness Limitations (AWLs) section of the Instructions for Continued Airworthiness by incorporating new limitations for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. This proposed AD would also require the initial inspection of a certain repetitive AWL inspection to phase in that inspection, and repair if necessary. This proposed AD results from a design review of the fuel tank systems. We are proposing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

The FAA proposes to adopt a new airworthiness directive (AD) for all Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD would require revising the FAA-approved maintenance program to incorporate new airworthiness limitations (AWLs) for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. This proposed AD would also require the initial inspection of a certain repetitive AWL inspection to phase in that inspection, and repair if necessary. This proposed AD results from a design review of the fuel tank systems. We are proposing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

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 certain Hawker Beechcraft Corporation F33 Series and Models G33, V35B, A36, A36TC, B36TC, 95-B55, D55, E55, A56TC, 58, and G58 airplanes and Raytheon Aircraft Company Models 58P, 58TC, and 77 airplanes. This proposed AD would require you to replace certain circuit breaker toggle switches with improved design circuit breaker toggle switches. This proposed AD results from reports of certain circuit breaker toggle switches used in various electrical systems throughout the affected airplanes overheating. We are proposing this AD to prevent failure of the circuit breaker toggle switch, which could result in smoke in the cockpit and the inability to turn off the switch.

We are adopting a new airworthiness directive (AD) that supersedes AD 2006-22-08, which applies to all Air Tractor, Inc. (Air Tractor) Models AT-602, AT-802, and AT-802A airplanes. AD 2006-22-08 currently requires you to repetitively inspect the engine mount for any cracks, repair or replace any cracked engine mount, and report any cracks found to the FAA. Since we issued AD 2006-22-08, the FAA has received reports of two Model AT- 802A airplanes with cracked engine mounts below the initial compliance time in AD 2006-22-08. The FAA has determined that an initial inspection is required when the airplane reaches a total of 1,300 hours time-in-service (TIS) instead of 4,000 hours TIS required by AD 2006- 22-08. Consequently, this AD retains the actions of AD 2006-22-08 while requiring the initial inspection when the airplane reaches a total of 1,300 hours TIS. We are issuing this AD to detect and correct cracks in the engine mount, which could result in failure of the engine mount. Such failure could lead to separation of the engine from 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 action revises Class E airspace at Red Dog, AK to provide adequate controlled airspace to contain aircraft executing Instrument Approach Procedures. Two Area Navigation (RNAV) Required Navigation Performance (RNP) Special Instrument Approach Procedures and an RNAV RNP Special Departure Procedure (DP) are being developed for the Red Dog Airport. This action revises existing Class E airspace upward from 1,200 feet (ft.) above the surface at Red Dog Airport, Red Dog, AK.

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 March 26, 2007, vol. 72, no. 57, page 14162. This collection establishes requirements for the certification, operation, and maintenance of light-sport aircraft.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 777-200, -200LR, -300, and -300ER series airplanes. This proposed AD would require revising the Airworthiness Limitations (AWLs) section of the Instructions for Continued Airworthiness by incorporating new limitations for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. This proposed AD also would require the initial performance of certain repetitive inspections specified in the AWLs to phase in those inspections, and repair if necessary. This proposed AD results from a design review of the fuel tank systems. We are proposing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 767-200, -300, -300F, and -400ER series airplanes. This proposed AD would require revising the FAA-approved maintenance program to incorporate new airworthiness limitations (AWLs) for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. This proposed AD would also require the initial inspection of certain repetitive AWL inspections to phase in those inspections, and repair if necessary. This proposed AD results from a design review of the fuel tank systems.

This action revises area navigation (RNAV) route Q-22 over the South Central United States by changing a waypoint name to eliminate confusion with similar sounding waypoints in close proximity to each other. The FAA is taking this action to enhance safety and to improve the efficient use of the navigable airspace.

This action confirms the effective date of a direct final rule that establishes a Class E airspace area at Dean Memorial Airport, Haverhill, NH (K5B9) to provide for adequate controlled airspace for those aircraft using the new Area Navigation (RNAV) Instrument Approach Procedure to the Airport.

This action revises Restricted Areas 3601A (R-3601A) and 3601B (R-3601B), at Brookville, KS, in response to a request from the United States Air Force (USAF). Specifically, this action revises R-3601A and R-3601B by combining their lateral boundaries, expanding the ceiling to flight level 230 (FL230), and re-designating the lower portion of the combined area as R-3601A and the upper portion as R-3601B. Additionally, this action changes the using agency of R-3601A and R- 3601B from ``Commander, Kansas ANG, McConnell AFB, KS'' to ``Air National Guard, 184th Air Refueling Wing, Detachment 1, Smoky Hill ANG Range, Salina, KS.'' These revisions will fulfill new USAF requirements for high altitude release bomb training for fighter aircraft and medium-to-high altitude release bomb training for bombers.

The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 207, Airport Security Access Control Systems.

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 airworthiness authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as an obstruction at the cargo compartment fire extinguisher system drier metering unit (DMU) inlet, affecting the system effectiveness and, consequently, making the fire extinguishing capability at those compartments inadequate should a fire erupt. We are issuing this AD to require actions to correct the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain McDonnell Douglas DC-10-30 and DC-10-30F airplanes. This AD requires installing Teflon sleeving around the fuel pump wire harness inside the conduit in the aft supplemental fuel tank. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.

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 proposes to adopt a new airworthiness directive (AD) for GE CF6-80C2A5F turbofan engines installed on Airbus A300 series airplanes. This proposed AD would require removing previous software versions from the engine electronic control unit (ECU). Engines with new version software will have increased margin to flameout. This proposed AD results from reports of engine flameout events during flight, including reports of events where all engines simultaneously experienced a flameout or other adverse operation. Although the root cause investigation is not yet complete, we believe that exposure to ice crystals during flight is associated with these flameout events. We are proposing this AD to minimize the potential of an all-engine flameout event caused by ice accretion and shedding during flight.

This action amends Class D airspace at Valdosta, Moody AFB, GA. The Air Education Training Command (AETC) T-6 mission at Moody AFB has been eliminated. Therefore, the requirement for a 7-mile radius of Moody AFB is no longer required. The Moody AFB Class D airspace is amended to airspace upward from the surface up to and including 2,700 MSL within a 5-mile radius of the airport.

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.

This notice proposes to amend Class E airspace at Mooresville, NC. Two Copter Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP) helicopter point in space approaches have been developed for Lowe's Mooresville Heliport, Mooresville, NC. As a result, additional controlled airspace extending upward from 700 feet Above Ground Level (AGL) is needed to accommodate the SIAPs and for Instrument Flight Rules (IFR) operations at Lowe's Mooresville Heliport. This action proposes to amend the Class E5 airspace for Mooresville, NC, to the south in order to include the point in space approaches serving Lowe's Mooresville Heliport.
