Federal Aviation Administration July 28, 2020 – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for certain Gulfstream Aerospace Corporation GVII-G500 airplanes. This proposed AD was prompted by a report of a fuel quantity disparity between the overhead panel touch screens and the touch screen controllers. This proposed AD would require incorporating operating limitations into the airplane flight manual (AFM) until the fuel quantity management system (FQMS) software is updated. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for all Air Tractor, Inc. (Air Tractor) Models AT-250, AT-300, AT-301, AT-302, AT-400, AT-400A, AT-401, AT-401A, AT-401B, AT-402, AT-402A, AT- 402B, AT-501, AT-502, AT-502A, AT-502B, AT-503, AT-503A, AT-504, AT- 602, AT-802, and AT-802A airplanes. This proposed AD was prompted by reports of cracks in the flap torque tube actuator attachment brackets that may cause the flap actuator to detach from the flap torque tube. This proposed AD would require repetitive visual and dye penetrant inspections of the flap actuator attachment bracket welds for cracks and replacement if cracks are identified. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2018-14-02, which applies to certain The Boeing Company Model 777-200, -200LR, -300, and -300ER series airplanes. AD 2018-14-02 requires an inspection for foam insulation on the dripshield above the overhead panel support structure and replacement if necessary. For certain airplanes, AD 2018-14-02 also requires replacement of foam insulation on the overhead panel support structure. Since the FAA issued AD 2018- 14-02, additional areas of Boeing Material Specification (BMS) 8-39 flexible urethane foam were found on the overhead panel support structure. This proposed AD would continue to require the actions in AD 2018-14-02, and, for certain airplanes, this proposed AD would require an inspection of the foam insulation on the overhead panel support structure, and replacement if necessary. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A330-200 series, Model A330-200 Freighter series, Model A330-300 series, Model A330-900 series, Model A340-200 series, Model A340-300 series, Model A340-500 series, Model A340-600 series, Model A380-800 series airplanes; and Model A350-941 and -1041 airplanes. This proposed AD was prompted by a report of a quality issue with a certain repair method of damage-through honeycomb core cargo linings by speed patches applied to both sides. This proposed AD would require a detailed inspection of each affected part and, depending on findings, repair of each affected part, or replacement with a serviceable part, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
