Airworthiness Directives; Airbus Airplanes
Document Number: 2016-10633
Type: Proposed Rule
Date: 2016-05-09
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A330-200 Freighter, -200, and -300 series airplanes; and Airbus Model A340-200, -300, -500, and -600 series airplanes. This proposed AD was prompted by reports of fuel leaking through fuel pump electrical connectors and fuel pump electrical connector damage caused by the build-up of moisture behind the electrical connector. Electrical connectors that become damaged by moisture can create an ignition source and a fuel leak. This proposed AD would require an inspection of the fuel pumps to identify their part numbers and replacement of affected pumps. We are proposing this AD to prevent a potential ignition source and a fuel leak due to damaged fuel pump electrical connectors. This condition creates a flammability risk in an area adjacent to the fuel tank.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2016-10524
Type: Rule
Date: 2016-05-09
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-300, -400, and -500 series airplanes. This AD was prompted by reports of fatigue cracking found at the left-side and right-side upper frames, at a certain area. This AD requires repetitive medium frequency eddy current (MFEC) inspections for cracking of the left-side and right-side upper frames, and repair (including open hole high frequency eddy current (HFEC) inspections for cracking of fastener holes) if necessary. This AD also provides an optional preventive modification, which terminates the repetitive inspections at the modified location. We are issuing this AD to detect and correct fatigue cracking of the upper frame, which can grow in size and result in a severed frame, leading to rapid decompression and consequent reduced structural integrity of the airplane.
Airworthiness Directives; Airbus Airplanes
Document Number: 2016-10287
Type: Rule

Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200, -200 Freighter, and -300 series airplanes; and Model A340-200 and -300 series airplanes. This AD was prompted by reports that cracks were found on an adjacent hole of certain frames of the center wing box (CWB). This AD requires removing fasteners, doing a rototest inspection of fastener holes, installing new fasteners, oversizing the holes and doing rototest inspections for cracks if necessary, and repairing any cracking that is found. We are issuing this AD to detect and correct cracking on certain holes of certain frames of the CWB that could affect the structural integrity of the airplane.
