Inspection Procedure. Refer to Eddy Current Method, paragraph 1.4.11 and Figure 6-16.
Place probe on a good area in the inspection location and null. Adjust phase as required to obtain horizontal lift-
Inspect the part.
Any signal similar to the notches in the test block is cause for rejection.
Either probe identified in paragraph 126.96.36.199 may be used depending primarily on the
ease of accessibility and user friendliness. If the probes are changed, steps 188.8.131.52 b.
(1), (2), and (3) shall be repeated each time a change is made.
Marking and Recording of Inspection Results. Mark and record the inspection results as required by
Backup Method. None required.
System Securing. The CPG cyclic stick forward and aft links, if removed, require installation in accordance with
the applicable technical manuals listed in Table 1-1.
CPG CYCLIC STICK REMOTE CONTROL LEVER (ET).
Description (Figure 6-1. Index No. 17). The CPG cyclic stick remote control lever is located on the CPG's cyclic
stick assembly, on the left side at the lower, mid portion.
Defects. This inspection is used to verify crack indications found visually on the CPG cyclic stick remote control
lever. No cracks are allowed.
Primary Method. Eddy Current.
NDI Equipment and Materials. (Refer to Appendix B.)
Eddy Current Inspection Unit
Probe, straight, shielded surface, 100 KHz-500 KHz
Probe, right angle, shielded surface, 100 KHz-500 KHz, 90 °
1/2 inch drop
Reference Block, three-notched aluminum (0.008, 0.020, and 0.040 EDM notches)

Preparation of Helicopter. The helicopter shall be prepared for safe ground maintenance. A partial
inspection for cause (visual indications, sites of mechanical damage, corrosion, etc.) may be performed on all exposed
surfaces of the installed part using this procedure. If required, the CPG cyclic stick remote control lever shall be removed
in accordance with the applicable technical manuals listed in Table 1-1.
