one of my recent projects

You never know what you'll find

 

Having a screw loose usually is not a good thing.
Are there supposed to be a guide on the top and bottom? Are those shavings from the cable?

 

Well you know you got twice as many cables there as you really need.....things like ailerons and rudders are for sissies all you really need is wing warping

 

I moved the guard out of the way to get at the cables. Look closely at the second from the right just above the guard. Yes, from the cable.

To bad he couldn't have learned something from the gipper

 

(LoL)

They should be glad you do your job. Caravans a great airplane but probably flies best with all its cables.

 

Are the first, second and third cable also worn?
Are these in a neutral position?
What are the guides made out of, phenolic?
Could there be a harmonic vibration through the airframe causing them to chatter, how much tension are on the cables?
What led you to check the cables, part of a routine inspection?
Looks like you have a great job.

1. No, but the 5th one was. The other elevator cable.
2. Yes
3. Yes, they are the original cable guides.
4. An STC repositioned the cables slightly and eliminated 1 of the guides. The cable tension is stock. The elevator cables are a lot higher than the rest so subject to wear sooner than the others.
5. Because of the STC and a known history of frayed cables because of it, this area is inspected every 100 flight hours even though it is not on the phase inspection or the STC's instructions for continued airworthiness.
6. Sometimes. It's not so great when the seasonal pressure is on, like now.

Permanently correcting the problem is easy. Getting the FAA to except the fix is hard.

 

Sounds like the Navy. I created an aligment procedure that would put an SRR13 radio receiver spot on, usually with < 3 microvolts sensitivity. (spec was 15) in less than 2 hours. The book procedure took 30 hours and was not anywhere near as accurate. BuShips wouldn't allow it.

There is no doubt in my military mind that I am not a military man.
