This is a good reminder to make sure you Don't take your condtion inspection for granted, and have another set of eyes look at with you. Most often, as the builder, you are blind to the errors you built into your own aircraft. I just thought this was a good example of inspection program that didn't work, finally someone actually "looked" and caught this before it turned ugly.

Special Safety Tip
Notice Number: NOTC3434
Here we have an excellent example of an accident that did not happen!
While an alert IA (or mechanic) discovered the discrepancy, it appears multiple mechanics and IAs missed "seeing" the incorrect installation. Initially, someone made the incorrect installation, and an Inspector missed it! This example can serve as a reminder that mechanics and Inspectors need to be diligent in performing their work.
As pilots and owners, we need to encourage mechanics not to shortcut any inspections! Our very lives may depend upon it!

While the Editor's comment in the GA Alert seems to praise the IA who discovered this one, the photos clearly demonstrate a failure to have the cable installed properly in the first place. It is possible there were many repeated inspections on this V35A over a number of years without anyone noticing the slow sawing action through the primary control tube. (Investigation revealed this particular airplane did not fly very often.)
We need to ask ourselves what we are relying on as the basis for the GA Quality Assurance program, as it relates to qualifications, training, recurrency, following directions, and performing proper inspections. This is a systemic challenge for maintenance facilities and individual mechanics alike.
