2011-11-05: We are superseding an existing airworthiness directive (AD) for the products listed above. That AD currently requires an inspection to determine if a certain fuel pump housing electrical connector is installed. The existing AD also requires a revision to the FAA-approved airplane flight manual (AFM) to advise the flightcrew of the appropriate procedures for disabling certain fuel pump electrical circuits following failure of a fuel pump housing electrical connector if applicable. The existing AD also requires the deactivation of certain fuel tanks or fuel pumps and the installation of placards if applicable. The existing AD allows the optional replacement of the fuel pump housing electrical connectors with new, improved parts, which would terminate the AFM revisions, deactivation of certain fuel tanks and fuel pumps, and placard installation. This new AD instead requires replacing the fuel pump housing electrical connector assembly with a new part and doing repetitive inspections for continuity, resistance, and insulation resistance, and doing corrective actions if necessary. This AD was prompted by reports of failures of a certain fuel pump housing electrical connector. We are issuing this AD to detect and correct insulation resistance degradation and arcing in the potted backside of the electrical connector assembly of the fuel boost/ transfer pump housing, which could compromise its performance and cause an ignition source in the fuel tank, resulting in a fuel tank explosion and consequent loss of the airplane.
2018-14-04: We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200 Freighter, A330-200, A330-300, A340-200, A340- 300, A340-500, and A340-600 series airplanes. This AD was prompted by a determination that a functional test to ensure that there is no blockage of vent pipes was not done on the trim tank of certain airplanes during production. This AD requires doing a trim tank functional test, and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.
2007-25-15: The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A300 series airplanes; and all Airbus Model A300-600 series airplanes.

94-11-05: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 767-200 and 767-300 series airplanes. This action requires repetitive inspections of the pumping unit assembly on the override and jettison fuel boost pump assemblies to detect looseness of the screws that attach the inlet diffuser assembly to the pumping unit housing, and repair or replacement of the pumping unit assembly with a serviceable assembly, if necessary. For certain airplanes, this AD also provides for deactivation of the center wing fuel tank as an alternative to the repetitive inspections. This amendment is prompted by reports of failures of the override and jettison fuel pumps due to damage to impeller units and pumping unit housings caused by loose diffuser rings in the fuel pump assemblies of these airplanes. During dry fuel operation, a loose diffuser ring may cause metal-to-metal contact. The actions specified in this AD are intended to prevent the generation of sparks and a potential ignition source inside the fuel tank caused by metal-to-metal contact during dry fuel pump operation.
2007-25-03: The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737-600, -700, -700C, -800, and -900 series airplanes. This AD requires repetitive inspections of either the aft side or forward side of the aft pressure bulkhead for oil can conditions or bulges, a one-time inspection of the aft pressure bulkhead to identify any previously installed web repair, and corrective actions if necessary. This AD results from web oil can conditions found on the aft pressure bulkhead of several airplanes. We are issuing this AD to detect and correct oil can conditions, bulges, or previous repairs in the aft pressure bulkhead, which could lead to web cracks and consequently result in rapid decompression of the airplane.
2001-11-04: This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) Models 99, 99A, 99A (FACH), A99, A99A, B99, and C99 airplanes. This AD requires you to inspect all main landing gear (MLG) hydraulic actuators to determine the end cap part number that is installed, and replace any actuator that has a part number 4A125C32 end cap. This AD is the result of the potential for fatigue cracks to develop on the MLG hydraulic actuator end caps. The actions specified by this AD are intended to eliminate existing and prevent future fatigue cracks in the MLG hydraulic actuator end caps. Such cracks could cause hydraulic fluid to leak and result in collapse of one or more gears with consequent aircraft damage and passenger injury.
