Federal Aviation Administration October 24, 2007 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Rolls-Royce plc RB211-524 Series Turbofan Engines
Document Number: E7-20923
Type: Proposed Rule
Date: 2007-10-24
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) provided by the aviation authority of the United Kingdom to identify and correct an unsafe condition on an aviation product. The MCAI states the following:
Airworthiness Directives; Cessna Aircraft Company Models 172R and 172S Airplanes
Document Number: E7-20862
Type: Proposed Rule
Date: 2007-10-24
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) Models 172R and 172S. This proposed AD would require you to inspect the fuel return line assembly for chafing; replace the fuel return line assembly if chafing is found; and inspect the clearance between the fuel return line assembly and both the right steering tube assembly and the airplane structure, adjusting as necessary. This proposed AD results from reports of chafed fuel return line assemblies, which were caused by the fuel return line assembly rubbing against the right steering tube assembly during full rudder pedal actuation. We are proposing this AD to detect and correct chafing of the fuel return line assembly, which could result in fuel leaking under the floor and fuel vapors entering the cabin. This condition could lead to fire under the floor or in the cabin area.
Airworthiness Directives; Airbus Model A300 Series Airplanes
Document Number: E7-20820
Type: Rule
Date: 2007-10-24
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A300 series airplanes. This AD requires revising the Airworthiness Limitations Section of the Instructions for Continued Airworthiness to incorporate new limitations for fuel tank systems. 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 caused by latent failures, alterations, repairs, or maintenance actions, could result in fuel tank explosions and consequent loss of the airplane.
Airworthiness Directives; Airbus Model A330 Airplanes
Document Number: E7-20817
Type: Rule
Date: 2007-10-24
Agency: Federal Aviation Administration, Department of Transportation
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:
Airworthiness Directives; Boeing Model 757-200, -200PF, and -200CB Series Airplanes
Document Number: E7-20816
Type: Rule
Date: 2007-10-24
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 757-200, -200PF, and -200CB series airplanes. This AD requires inspections to detect scribe lines and cracks of the fuselage skin, lap joints, circumferential butt splice strap, and external and internal approved repairs; and related investigative/ corrective actions if necessary. This AD results from reports of scribe lines adjacent to the skin lap joints. We are issuing this AD to detect and correct cracks, which could grow and cause rapid decompression of the airplane.
Airworthiness Directives; Airbus Model A300-600 Series Airplanes
Document Number: E7-20815
Type: Rule
Date: 2007-10-24
Agency: Federal Aviation Administration, Department of Transportation
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:
Airworthiness Directives; Fokker Model F.28 Mark 0070 and 0100 Airplanes
Document Number: E7-20814
Type: Rule
Date: 2007-10-24
Agency: Federal Aviation Administration, Department of Transportation
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:
Airworthiness Directives; General Electric Company (GE) CF6-80C2D1F Turbofan Engines
Document Number: E7-20813
Type: Rule
Date: 2007-10-24
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for GE CF6-80C2D1F turbofan engines, installed on, but not limited to, McDonnell Douglas Corporation MD-11 series 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 engine flameout caused by ice accretion and shedding during flight.
Establishment of Class E Airspace; Hailey, ID
Document Number: E7-20796
Type: Rule
Date: 2007-10-24
Agency: Federal Aviation Administration, Department of Transportation
This action corrects a final rule published in the Federal Register August 30, 2007 (72 FR 50046), Airspace Docket No. 07-ANM-8, FAA Docket No. FAA-2007-27911. In that rule, an error was made in the legal description for Hailey, ID. Specifically, the longitude referencing Friedman Memorial Airport, ID stated ``* * *long. 114[deg]17'45'' W.'' instead of ``* * *long.114[deg]17'44'' W.'' This action corrects that error.
Airworthiness Directives; McDonnell Douglas Model DC-8-53, DC-8-55, DC-8F-54, and DC-8F-55 Airplanes; and Model DC-8-60, DC-8-60F, DC-8-70, and DC-8-70F Series Airplanes
Document Number: E7-20464
Type: Rule
Date: 2007-10-24
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain McDonnell Douglas airplanes, identified above. This AD requires a one-time inspection to determine the configuration of the airplane. This AD also requires repetitive inspections for cracking of the tee or angle doubler, and corrective actions if necessary. This AD results from a report indicating that numerous operators have found cracks on the tee. We are issuing this AD to detect and correct stress corrosion cracking of the tee or angle doubler installed on the flat aft pressure bulkhead. Cracking in this area could continue to progress and damage the adjacent structure, which could result in loss of structural integrity of the airplane.
Airworthiness Directives; British Aerospace Regional Aircraft Model HP.137 Jetstream Mk.1, Jetstream Series 200, Jetstream Series 3101, and Jetstream Model 3201 Airplanes
