TASK 24-92-00-210-023-A
Check that Connector is Correctly Tightened by Measurement of the Resistance with a Loop Tester ...

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.
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: MAKE SURE THAT YOU OBEY ALL THE WARNINGS AND THE CAUTIONS INCLUDED IN THE REFERENCED PROCEDURES.

A. Measurement of the Resistance with a Loop Tester
F Location of the Loop Tester Measurement Points
   (1) Do a loop impedance test at connectors (Ref. AMM TASK 20-28-00-720-014):
  • 4005VC, 4007VC, 4009VC, 4011VC, 4013VC, 4015VC, 4017VC, 4019VC, LH side
