______________________________________________
 1. General
_______
R During flight, the aircraft becomes charged with static electricity. If the discharge of the static electricity is not controlled, it causes interference in the communications and navigation systems.
 To decrease the effect of this interference, static dischargers are installed.

 3. System Description
__________________ Each static discharger assembly has a retainer and a static discharger. The retainer is attached to the structure by rivets. The static discharger is attached to its retainer by one screw, to make it easy to replace.
 Static discharger assemblies are installed at the tips of:
 -
the wing-tip fence

 -
the horizontal stabilizer

 -
the vertical stabilizer

 -
the elevators

 -
the rudder
 and on the trailing edges of:

 -
the wing fixed structure

 -
the ailerons

 -
the elevators

 -
the rudder

 -
the flap-track movable-fairings

 -
the engine-pylon rear-fairings.

 Two types of retainer are installed:
 -a flat retainer at the trailing edges
 -an angular retainer at the tips.
 Two types of static discharger are installed:
 - one with a straight mounting, installed at the trailing edges
 - one with a 30-degree angle mounting, installed at the tips.

 The two types are not interchangeable.

____________ R Not Applicable.
 5. Interface
_________ R Not Applicable.
 6. Operation/Control and Indicating
________________________________
 The static dischargers:

 -decrease the voltage level necessary to start corona discharge
 -make regions of very low radio-frequency field-strength and thus cause the discharge to occur in these regions
 -discharge the static electricity charge.
 The effect is to decrease the interference in the communications and navigation systems.
