Inspection Procedure. Refer to Eddy Current Method, paragraph 1.4.11 and Figure 6-32.
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
Marking and Recording of Inspection Results. Mark and record the inspection results as required by
Backup Method. None required.
System Securing. The pilot longitudinal SPAD outer and inner levers require installation in accordance with the
applicable technical manuals listed in Table 1-1.
PILOTICPG DIRECTIONAL CONTROL PEDAL RELEASE HANDLE (ET).
Description (Figure 6-1. Index No. 33). The pilot/CPG directional control pedal release handles are differently
shaped but similar in function. Each handle is found in the pilot/CPG compartments, just forward of the cyclic control
Defects. This inspection is used to verify crack indications found visually on the pilot/CPG directional control
pedal release handle. 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 pilot/CPG directional control pedal release handle shall be
removed in accordance with the applicable technical manuals listed in Table 1-1.
