Section 51-80
Electrical Bonding
1. General
The bonding system gives the airplane good lightning protection. A special bonding system is
necessary for the composite structure of the DA 40. Without this special system, the composite
structure would not sufficiently conduct electricity.
Refer to Section 21-60 for details about the static discharge wicks.
2. Description
Figure 1 shows a simplified bonding system schematic.
The lightning conductor system is the main part of the bonding system. High capacity aluminum alloy
tubes and strips make the lightning conductor system.
The lightning conductor system has a longitudinal branch and a lateral branch. The longitudinal branch
runs from the engine block via engine truss, firewall, cabin, aft fuselage and empennage to the
elevator. The horizontal branch connects the left wing tip with the right wing tip. It is connected with
the longitudinal branch at the cabin floor under the forward seats.
Metal braiding and strips connect all conductive components (for example: wing skin, fuel tanks,
control systems, landing gear, engine, etc.) and antenna ground plates to the lightning conductor
system.
