Federal Aviation Administration June 29, 2011 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; The Boeing Company Model 747-100, 747-100B, 747-200B, 747-200C, 747-200F, 747-300, 747SR, and 747SP Series Airplanes
Document Number: 2011-16370
Type: Proposed Rule
Date: 2011-06-29
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Model 747 series airplanes. The existing AD currently requires repetitive inspections for cracks of the fuselage skin lap splice between body station (BS) 400 and BS 520 at stringers S-6L and S-6R, and repair if necessary. This proposed AD would shorten the interval for the repetitive inspections, require modification for certain airplanes, and require certain post- modification inspections for other airplanes. This proposed AD results from reports of multiple adjacent cracks on an airplane, and a recent fleet-wide evaluation of widespread fatigue damage of skin lap joints, which indicated the need for revised procedures and reduced compliance times. We are proposing this AD to detect and correct cracking of the fuselage skin lap splice between BS 400 and BS 520 at stringers S-6L and S-6R. Such cracking could result in sudden loss of cabin pressurization and the inability of the fuselage to withstand fail-safe loads.
Airworthiness Directives; The Boeing Company Model 777 Airplanes
Document Number: 2011-16368
Type: Proposed Rule
Date: 2011-06-29
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD would require repetitive detailed inspection and high frequency eddy current (HFEC) inspections for cracks of the wing center section (WCS) spanwise beams, and repair if necessary. This proposed AD was prompted by reports of cracks found in the web pockets of the WCS spanwise beams. We are proposing this AD to detect and correct cracking in the WCS spanwise beams, which could result in reduced structural integrity of the wings.
Airworthiness Directives; Airbus Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes) and A310 Series Airplanes

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:
