(b) Examine the aluminum diverter strips for loose fasteners, burned areas, and corrosion.
NOTE: Sharp corners, or points on the conductive strip can cause radio interference.
SUBTASK 53-52-00-410-009
(3) Close the radome. Do this task :Nose Radome - Close, TASK 53-52-00-410-802..
SUBTASK 53-52-00-280-002
(4) Do the steps that follow to measure the conductivity with an intrinsically safe approved bonding
meter, COM-1550:
(a) With the radome open, measure the resistance between the ends of the diverter strips.
1) Make sure that the resistance is not more than 0.01 ohm.
NOTE: Use a test probe with a sharp point to go through the paint or epoxy on the
strip.
(b) Measure the electrical resistance between the conductor strap and diverter strip in
Figure 601.
1) Make sure that the resistance is not more than 0.01 ohm.
(c) With the radome closed, measure the electrical resistance between the conductor straps
on the radome and body structure skin.
NOTE: Required only where the radome clip contacts the radome conductor strap.
1) Make sure that the resistance is not more than 0.03 ohm.
(d) With the radome open, measure the electrical resistance between the radome clips and
airframe bulkhead.
NOTE: Required only where the radome clip contacts the radome conductor strap.
1) Make sure that the resistance is less than 0.01 ohms.
SUBTASK 53-52-00-210-004
(5) If there is damage, replace the radome.
(a) Do this task: (Nose Radome Removal, TASK 53-52-00-000-801)
(b) Do this task: (Nose Radome Installation, TASK 53-52-00-400-801)
F. Procedure - Do a Check of the Director Bar for the Glide Slope Antenna
SUBTASK 53-52-00-210-005
(1) Do a check for damage of the director bar for the glide slope antenna.
NOTE: The antenna director bar is a 13 in. (33 cm) continuous strip of aluminum foil tape. The
strip is installed horizontally across the centerline on the inner surface of the nose
radome.
SUBTASK 53-52-00-210-006
(2) Make sure the attachment of the director bar is satisfactory.
SUBTASK 53-52-00-960-001
(3) If you find damage or an unsatisfactory bond of the director bar for the glide slope antenna
replace the director bar.
(a) Do this task: (Glide Slope Director Bar Removal, TASK 53-52-31-000-801).
(b) Do this task: (Glide Slope Director Bar Installation, TASK 53-52-31-400-801).
