Airworthiness Directives; Vulcanair S.p.A. Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Vulcanair S.p.A. Model V1.0 airplanes. 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 identifies the unsafe condition as corrosion on the lower fuselage truss. This proposed AD would require a detailed visual inspection of the right- hand (RH) and left-hand (LH) lower rear attachments of the fuselage truss for corrosion, a tactile inspection of the lower rear attachments for missing sealant, and a general visual inspection of the lower fuselage truss welded pipes for corrosion and the related rivets for missing stems and, depending on findings, additional inspections and actions (including a tap test) and applicable corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
The FAA proposes to supersede Airworthiness Directive (AD) 2020-06-10, which applies to certain Airbus SAS Model A318 series airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2020-06-10 requires repetitive inspections for cracking of the vertical stiffeners of the left- and right-hand sides of the window frames and corrective actions if necessary. Since the FAA issued AD 2020-06-10, it was determined that certain compliance times need to be reduced. This proposed AD would retain the requirements of AD 2020-06-10, with amended compliance times, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A330-200 series airplanes; Model A330-200 Freighter series airplanes; Model A330-300 series airplanes; Model A330-800 series airplanes; Model A330-900 series airplanes; Model A340- 200 series airplanes; and Model A340-300 series airplanes. This proposed AD was prompted by a report of cracks found in the fuel control unit housing assembly of a Honeywell GTCP331-350 auxiliary power unit (APU), which caused fuel leakage in the APU compartment. This proposed AD would require replacing any affected APU fuel control unit or affected APU, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). This proposed AD would also prohibit the installation of affected parts under certain conditions. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
The FAA is superseding Airworthiness Directive (AD) 2008-23- 01, which applies to certain Airbus SAS Model A318, A319, A320, and A321 series airplanes. AD 2008-23-01 required inspecting to determine the part number and serial number of the fuel tank boost pumps and, for airplanes with affected pumps, revising the operator's airplane flight manual (AFM) and FAA-approved maintenance program. AD 2008-23-01 also required modifying or replacing certain fuel tank boost pumps, which terminated the AFM limitations and the maintenance program revisions. Since the FAA issued AD 2008-23-01, it has been determined that airplanes fitted with a different fuel pump can be subject to cavitation erosion on the wiring conduit. This AD requires inspecting affected fuel pumps for discrepancies and replacement if necessary, as specified in a European Union Aviation Safety Agency (EASA). This AD also requires replacing certain other fuel pumps. This AD also limits the installation of affected fuel pumps under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Hamilton Sundstrand Corporation Propellers
The FAA proposes to adopt a new airworthiness directive (AD) for all Hamilton Sundstrand Corporation (Hamilton Sundstrand) Model 14SF-17 and 14SF-19 propellers. This proposed AD was prompted by a report of an auxiliary motor and pump failing to feather a propeller in flight. This proposed AD would require replacement of a certain auxiliary motor and pump. This proposed AD would also prohibit installation of a certain auxiliary motor and pump on any propeller. The FAA is proposing this AD to address the unsafe condition on these products.
