AMC E 135 Electrical Bonding

Electrical bonding is a means to protect against the effects of electro-static discharges and currents from electrical Faults. The overall intent of CS-E 135 is to ensure that:

(i)a main Engine earth is provided. This is generally achieved by showing that all the elements of the Engine carcass are electrically bonded together.

(ii)a current path for electrical bonding exists between certain components that are mounted externally to the Engine and the main Engine earth. With respect to the accumulation of electro-static or electrical charge, the applicant should show that the modules, assemblies, components and accessories installed in or on the Engine are electrically bonded to the main Engine earth. This may be accomplished by examination of the type design drawings, electrical continuity checks, or actual inspection of a representative Engine.
