Aircraft Bonding Jumper

Aircraft Bonding Jumper

There were various types of bonding jumper i.e. P/N MS25083-2BB4, P/N BACJ40A20-9, P/N BACJ40K5A5A6, P/N BACJ40AD57-11 and P/N 69-14402-1 installed on Boeing airplane at various locations.

The following are partial description of the referenced bonding jumpers:

a) Bond Jumper P/N MS25083-2BB4 JUMPER ASSEMBLY, ELECTRIC, BONDING AND CURRENT RETURN (S/S BY MIL-C-83413/8) (per Mil-C-25083 4.0 inch long)

b) Bond Jumper P/N BACJ40A20-9 JUMPER ASSEMBLY, BONDING, COPPER, 35 AMPERE (0.190 & 0.190 Studs, 9 Inch Long)

c) Bond Jumper P/N BACJ40K5A5A6 JUMPER, BONDING, IRRADIATED, POLYOLEFIN, NYLON INSULATED TERMINAL (BMS3-11 RESISTANT) (0.190 & 0.190 Studs, 6 inch long)

d) Bond Jumper P/N BACJ40AD57-11 JUMPER ASSEMBLY, 35 AMPERE (0.250 & 0.375 studs, 11 inch long)

e) Bond Jumper P/N 69-14402-1 STATIC BONDING JUMPER, 60 amp braided tinned copper stranding (9.60 INCH LONG, STUD HOLES SLOTTED 0.14 radius WITH 0.10 CENTER OFFSET both ends)

The bonding check after installation is available via D6-54446 Standard Wiring Practices Manual (SWPM) Subject 20-20-00, and depends on the surface material and stud diameter.

Selection of a bonding jumper is based on current and frequency requirements and characteristics, material compatibility, installation geometry, environment, etc.
The selection of bonding jumpers is determined by the engineering design organization based on the specific requirements for the environment, application and other factors available at the time of design as discussed above. The reasons for a determination of a specific selection or design are not recorded, at least not with the selection. The parts or specification are available for each location in the respective IPC chapters listing the components for each area. Operator is encouraged to adhere to this selection or as specified in the drawing if not listed in the IPC.

Any deviations from the design drawing must be evaluated by Boeing.
