2001-12-03: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 767-300 series airplanes, that requires a one-time general visual inspection to find chafing and determine adequate clearance of certain wire bundles in the ceiling panel near the main passenger door, and corrective actions. The actions specified by this AD are intended to prevent damage to the wires in the bundles due to contact between the bundles and the adjacent ceiling support bracket. Such damage could result in electrical arcing, smoke, or fire in the cabin, and failure of certain systems essential to safe flight and landing of the airplane. This action is intended to address the identified unsafe condition.
2007-26-01: We are adopting a new airworthiness directive (AD) for certain Thrush Aircraft, Inc. (Thrush) Model S2R series airplanes. This AD requires you to do repetitive visual inspections of the vertical and horizontal stabilizer attach fitting, attach fitting bolts, and the vertical fin aft spar for cracks or corrosion. This AD also requires immediate replacement of the vertical and horizontal stabilizer attach fittings and attach fitting bolts if cracked or corroded parts are found, and the inspection of the vertical fin aft spar with repair or replacement if cracks or corrosion are found. This AD requires the eventual replacement of the vertical and horizontal stabilizer attach fittings and attach fitting bolts if no corrosion or cracks are found as terminating action for the repetitive inspections. This AD results from reports of cracks in the empennage of Thrush S2R series airplanes. We are issuing this AD to detect and correct these cracks, which could cause the vertical stabilizer to lose structural integrity. This failure could lead to loss of control.
94-12-11: This amendment adopts a new airworthiness directive (AD) that is applicable to all Boeing Model 747-400 series airplanes. This action requires revising the Airplane Flight Manual to include procedures that will enable the flight crew to identify fuel system leaks and to take appropriate action to prevent further fuel loss. This amendment is prompted by reports that flight crew procedures related to fuel system leaks are not defined adequately in the FAA-approved AFM for these airplanes. The actions specified in this AD are intended to ensure that the flight crew is advised of the potential hazard related to fuel exhaustion due to undetected leakage, and the procedures necessary to address it.
2001-12-05: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 747-100, 747-200, 747-300, and 747SR series airplanes powered by General Electric CF6-45/50 and Pratt & Whitney JT9D-70 series engines. This action requires a detailed visual inspection of the outboard diagonal brace for heat damage and cracking; and follow-on repetitive inspections or corrective actions, if necessary. This action also provides an optional terminating action for the requirements of this AD. This action is necessary to detect and correct heat damage to the diagonal brace, which could cause cracking or fracture of the diagonal brace, and possible loss of the diagonal brace load path and consequent separation of the strut and engine from the airplane.
2020-02-20: The FAA is superseding Airworthiness Directive (AD) 2014-24- 07, which applied to certain Airbus SAS Model A318 series airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; A320-211, -212, -214, -231, -232, and -233 airplanes; and Model A321- 111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2014- 24-07 required repetitive rototest inspections for cracking; corrective actions if necessary; and modification of the torsion box, which terminates the repetitive inspections. This AD continues to require the actions in AD 2014-24-07, with certain revised compliance times, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by a report of a crack found in the side box beam flange of the fuselage at the frame (FR) 43 level during a fatigue test campaign. The FAA is issuing this AD to address the unsafe condition on these products.
94-12-04: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 747 series airplanes, that requires repetitive inspections to detect cracking in certain fuselage skin lap joints, and repair, if necessary. This amendment is prompted by the results of extensive pressure fatigue tests conducted by the manufacturer. The actions specified by this AD are intended to detect and repair fatigue cracking in certain lap joints, which will ensure safe operation of airplanes that have exceeded their economic design goal.
2007-26-03: The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747-200C and -200F series airplanes. This AD requires, among other actions, installing mounting brackets, support angles, and moisture curtains in the main equipment center. This AD results from reports of water contamination in the electrical/ electronic units in the main equipment center. We are issuing this AD to prevent water contamination of the electrical/electronic units, which could cause the electrical/electronic units to malfunction, and as a consequence, could adversely affect the airplane's continued safe flight.
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. This AD requires inspecting to determine the part number of the sliding rods of the main landing gear (MLG) retraction actuators. For MLG retraction actuators equipped with sliding rods having certain part numbers, the AD also requires inspecting for discrepancies, including but not limited to cracking, of the sliding rod; and performing corrective actions if necessary. This AD also requires returning affected sliding rods to the manufacturer. This AD results from a report of a failure of a sliding rod of the MLG retraction actuator before the actuator reached the life limit established by the manufacturer. We are issuing this AD to prevent failure of the sliding rod of the MLG retraction actuator, which could result in reduced structural integrity of the MLG.
