Service Instruction SK-S1004 calls for replacement of the Garmin pitch servo bridle clamps because the plastic ones may allow the cables to slip. However, the service instruction assumes that the replacement clamps will be fitted in the same positions as the original clamps. If the clamps have slipped the positions may be wrong!

What is the full procedure for positioning the replacement bridle clamps if the originals have already slipped?

The question is not hypothetical. My FX-3 autopilot worked in pitch modes up to October 11th but after that flight all the symptoms, and data log analysis, seem to indicate the pitch servo is no longer connected to the elevator cables.

The G3X installation manual seems to require the servo capstan to be centered when the elevator is in the middle of its control range. Is that correct? (The middle of the range is not zero elevator deflection).

I plan to take the belly panel off tomorrow and hope someone can point me to an approved procedure.

Thanks,
Andy
