Federal Aviation Administration June 24, 2008 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Airbus Model A330-200, A330-300, and A340-300 Series Airplanes
Document Number: E8-14192
Type: Proposed Rule
Date: 2008-06-24
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) 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; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 190 Airplanes
Document Number: E8-14187

Airworthiness Directives; Boeing Model 737-600, -700, and -800 Series Airplanes
Document Number: E8-14185
Type: Proposed Rule
Date: 2008-06-24
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Boeing Model 737-600, -700, and -800 series airplanes. This proposed AD would require inspecting the free flange of the lower stringers of the wing center section for drill starts, and applicable related investigative and corrective actions. This proposed AD results from drill starts being found on the free flange of the lower stringers of the wing center section during a quality assurance inspection at the final assembly plant. We are proposing this AD to prevent cracks from propagating from drill starts in the free flange of the lower stringers of the wing center section, which could cause a loss of structural integrity of the wing center section and may result in a fuel leak.
Airworthiness Directives; Airbus Model A318, A319, A320, and A321 Series Airplanes
Document Number: E8-14184

Airworthiness Directives; Boeing Model 737-300, -400, and -500 Series Airplanes
Document Number: E8-14183
Type: Proposed Rule
Date: 2008-06-24
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Boeing Model 737-300, -400, and -500 series airplanes. This proposed AD would require repetitive high frequency eddy current (HFEC) inspections for cracking of the 1.04-inch nominal diameter wire penetration hole in the frame and frame reinforcement, between stringers S-20 and S-21, on both the left and right sides of the airplane, and related investigative/ corrective actions if necessary. This proposed AD results from reports of cracking in the frame, or in the frame and frame reinforcement, common to the 1.04-inch nominal diameter wire penetration hole intended for wire routing. We are proposing this AD to detect and correct cracking in the fuselage frames and frame reinforcements, which could reduce the structural capability of the frames to sustain limit loads, and result in cracking in the fuselage skin and subsequent rapid depressurization of the airplane.
