TASK 23-61-00-200-001-A
Resistance Check from the Tip to the Retainer and Bonding Check from the Retainer to the Aircraft Structure


WARNING: PUT THE SAFETY DEVICES AND THE WARNING NOTICES IN POSITION BEFORE YOU START A TASK ON OR NEAR:
  • THE FLIGHT CONTROLS
  • THE FLIGHT CONTROL SURFACES
  • THE LANDING GEAR AND THE RELATED DOORS
  • COMPONENTS THAT MOVE.
MOVEMENT OF COMPONENTS CAN KILL OR CAUSE INJURY TO PERSONS AND/OR CAN CAUSE DAMAGE TO THE EQUIPMENT.
WARNING: BEFORE YOU START WORK, YOU MUST PUT ON A SAFETY HARNESS AND ATTACH IT TO THE ACCESS PLATFORM. WITHOUT A SAFETY HARNESS, YOU CAN FALL. THIS CAN KILL YOU OR CAUSE YOU INJURY.
WARNING: MAKE SURE THAT THE GROUND SAFETY-LOCKS ARE IN POSITION ON THE LANDING GEAR. THIS WILL PREVENT UNWANTED MOVEMENT OF THE LANDING GEAR, AND THUS POSSIBLE INJURY TO PERSONS AND DAMAGE TO THE AIRCRAFT AND/OR EQUIPMENT.

Subtask 23-61-00-941-050-A
A. Safety Precautions
   (1) As necessary, use the applicable SAFETY BARRIERS, specified by the operator's instructions and your local regulations.
   (2) Put the ACCESS PLATFORM 12M (40 FT) - ADJUSTABLE in position below the applicable zone.
   (3) Put the WARNING NOTICE(S) in position to tell persons not to operate the flight controls.
4. Procedure
Subtask 23-61-00-210-050-A
A. Inspection of the Static Dischargers
   (1) Examine the static dischargers to make sure that:
  • There is no distortion.
  • There is no important damage to the covers.
  • There is no corrosion on the bases.
  • There is no damage to the tips.
  • The screws are tight and serviceable.
  • They are correctly attached.
NOTE: A small damage like cosmetic or superficial damage is permitted.

B. Bonding Resistance
   (1) Make sure that the bonding resistance between the static discharger retainer and the aircraft structure is correct (Ref. AMM TASK 20-28-00-869-002).
   (2) For the bonding resistance between the static discharger tip and the static discharger retainer:
     (a) Measure the resistance between the tip of the static discharger and the static discharger retainer (with the MEGOHMMETER 500 MOHMS set to 500 VDC) as follows:
  • Connect one probe to the tip of the applicable static discharger.
  • Put the other probe against the side of the applicable static discharger retainer.
  • With one lead attached to the retainer, attach the other lead to a piece of wet SPONGE or the ABRASIVE - FINE WIRE WOOL (to touch the tip of the static discharger).
     (b) Measure the resistance values that follow:
  • For type A, between 6 and 120 megohms
  • For type B, between 6 and 200 megohms.
