Federal Aviation Administration October 11, 2007 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; McDonnell Douglas Model 717-200 Airplanes
Document Number: E7-20051
Type: Proposed Rule
Date: 2007-10-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain McDonnell Douglas Model 717-200 airplanes. This proposed AD would require electrical bonding of the fill valves for the right and left main fuel tanks, the fill valve and pipe assembly for the center wing fuel tank, and the defuel shutoff valve. This proposed AD results from a fuel system review conducted by the manufacturer. We are proposing this AD to prevent improper bonding of the fill valves and defuel shutoff valve for the main fuel tanks and center wing tank, which, in combination with a lightning strike, could result in a fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; McDonnell Douglas Model 717-200 Airplanes
Document Number: E7-20049
Type: Proposed Rule
Date: 2007-10-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain McDonnell Douglas Model 717-200 airplanes. This proposed AD would require modification of the conduit for the forward boost pump of the center fuel tank. This proposed AD results from the finding that a potential chafing condition exists in the volute assembly of the forward boost pump for the center fuel tank. We are proposing this AD to prevent chafing of the forward boost pump wiring that could lead to arcing to the inside of the 45-degree angle fitting, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; Boeing Model 737-100, -200, -200C, -300, -400, and -500 Series Airplanes
Document Number: E7-20048
Type: Proposed Rule
Date: 2007-10-11
Agency: Federal Aviation Administration, Department of Transportation
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 repetitive inspections for cracking in and around the upper and lower hinge cutouts of the forward entry and forward galley service doorways, and corrective actions if necessary. This proposed AD results from multiple reports of cracks found in the skin, bearstrap, and/or frame outer chord in the hinge cutout areas of the forward entry and forward galley service doorways. We are proposing this AD to detect and correct such cracking, which could result in rapid decompression of the airplane.
Airworthiness Directives; Alpha Aviation Design Limited (Type Certificate No. A48EU Previously Held by APEX Aircraft and Avions Pierre ROBIN) Model R2160 Airplanes
Document Number: E7-20047
Type: Proposed Rule
Date: 2007-10-11
Agency: Federal Aviation Administration, Department of Transportation
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:
Airworthiness Directives; General Electric Company (GE) CF6-80C2A5F Turbofan Engines
Document Number: E7-20036
Type: Rule
Date: 2007-10-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for GE CF6-80C2A5F turbofan engines installed on, but not limited to, Airbus A300F4-605R airplanes. This AD requires removing previous software versions from the engine electronic control unit (ECU). Engines with new version software will have increased margin to flameout. This 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 issuing this AD to minimize the potential of an all-engine flameout event caused by ice accretion and shedding during flight.
Special Conditions: Boeing Model 787-8 Airplane; Composite Wing and Fuel Tank Structure-Fire Protection Requirements
Document Number: E7-20031
Type: Rule
Date: 2007-10-11
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for the Boeing Model 787-8 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 novel or unusual design features are associated with composite materials chosen for the construction of the fuel tank skin and structure. For these design features, the applicable airworthiness regulations do not contain adequate or appropriate safety standards for wing and fuel tank structure with respect to postcrash fire safety. These 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 standards. We will issue additional special conditions for other novel or unusual design features of the Boeing Model 787-8 airplanes.
Special Conditions: Boeing Model 787-8 Airplane; Lithium Ion Battery Installation
Document Number: E7-19980
Type: Rule
Date: 2007-10-11
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for the Boeing Model 787-8 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. The Boeing Model 787-8 airplanes will use high capacity lithium ion battery technology in on- board systems. For these design features, the applicable airworthiness regulations do not contain adequate or appropriate safety standards. These 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 standards. Additional special conditions will be issued for other novel or unusual design features of the Boeing Model 787-8 airplanes.
Airworthiness Directives; International Aero Engines (IAE) V2500 Series Turbofan Engines
Document Number: E7-19924
Type: Rule
Date: 2007-10-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for International Aero Engines (IAE) V2500 series turbofan engines. This AD requires repetitive monitoring of N2 vibration on all IAE V2500 series engines to identify engines that might have a cracked high pressure turbine (HPT) stage 2 air seal. This AD results from a report that HPT stage 2 air seals have developed cracks. We are issuing this AD to prevent uncontained failure of the HPT stage 2 air seal.
Airworthiness Directives; Raytheon Aircraft Company Models 58P and 58TC Airplanes
Document Number: E7-19888
Type: Rule
Date: 2007-10-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA adopts a new airworthiness directive (AD) for certain Raytheon Aircraft Company (RAC) Models 58P and 58TC airplanes that were used as lead airplanes by the United States Forest Service (USFS). This AD establishes new limits for the structural life of the airframe (wing, fuselage, empennage, and associated structure) through the incorporation of a supplement to the Limitations Section of the pilot's operating handbook and airplane flight manual (POH/AFM). This AD results from the FAA's analysis and determination that the operational history and usage of the affected airplanes requires a reduction in the structural life limit to 4,500 hours time-in-service (TIS) for the airframe (wing, fuselage, empennage, and associated structure). We are issuing this AD to prevent structural failure of the airframe (wing, fuselage, empennage, or associated structure) based on the operational history and usage of the affected airplanes. Such failure could lead to loss of control.
