Wings

For reports pertaining to the center wing box structure.

Fuel

The units and components storing and delivering fuel to the engine. Includes the integral tank leakdetection and sealing. Does not include the structure of integral, tip fuel tanks, fuel cell backing boardscovered in the structures JASC Chapters 53 and 57, or the fuel flow rate sensing, transmitting, orindicating systems which are covered in JASC Chapter 73. Use this code for fuel system reports withinsufficient information to file in a more specific JASC 2800 series code. This code is also used to reportproblems involving two or more aircraft fuel system JASC codes.

Wings

For reports of the auxiliary or miscellaneous wing structure. Includes the secondary items used forattachment. Does not include reports for plates or skins. Typical parts are wing tip, clips, brackets,channels, angles, stiffeners, doublers, etc.

Fuel

The portion of the fuel system used for the storage of fuel. Does not include defects in the wing primarystructure of integral tanks. Typical parts are removable metal tank, tip tank, header tank, bladder fuelcell, tank interconnect lines, vent line, vent valve, drain valve, filler cap, filler neck, check valve, venttube, cap seal, filler adapter, outlet fitting, screen, fueling panel, tank strap, sealant, etc.

Wings

For reports of the exterior covering of the wing including the access covers, tip tank fillets, or fairings.Includes the leading edge and trailing edge skin and wing mounted fuel compartment panels.

Fuel

The portion of the aircraft fuel system other than selector valves, transfer valves, electric motor drivenpumps used to distribute fuel from the tank outlet to the powerplant quick disconnect or up to the strainerunit. Includes the engine primer equipment, the switch that senses failure of a system pump, and theswitch that automatically activates the boost pump. Typical parts are line, fitting, primer, nozzle, primerpump, actuating linkage for the fuel selector/shutoff valve, etc.

Wings

The structure on the wing used for the attachment of fuselage, nacelle or pylon, and landing gear to thewing and for the support of equipment within the wing. Use this code for reports of wing attachmentsthat can not be specifically identified in JASC codes 5741 through 5744. Does not include flight controlor landing gear actuator support fittings which should be coded in the appropriate JASC 2700 or 3200series code.

Fuel

The component that filters unmetered fuel upstream of the engine fuel control/carburetor. Does notinclude the engine fuel metered control system filters (filed in JASC code 7300). Typical parts arescreen, housing, bowl, gasket, plunger, stand pipe, etc.

Wings

The fittings on the wing used for attachment to the fuselage structure.

Fuel

The electric motor/engine driven pumps providing fuel under pressure to the engine fuelcontrol/carburetor for starting and emergency use. Includes parts of the pump, associated motor, andelectrical circuitry/switch. Does not include pressure switch indicating system. Typical parts arehousing, seal, motor, brush, bearing, connector, and fuel transfer pump, etc.
