Par-alketone

[SpecialT]

Has anyone heard of using par-alketone to wipe control cables for corrosion protection? Does it attract grime and dirt? Experimental planes only?

Long ago while maintaining fire fighting planes for Rosenbaulm Aviation in Medford, OR, that was one of the winter jobs was wiping that stuff on the cables in the back of the aircraft, it dried, was flexible, but not sticky, gary

I understand it to be standard practice.

I was surprised to see it is not listed in AC43.13-1b. May be in the AMT manual for airframes or general.

My first encounter with it was in the '60s. Have some in my shop now. Good for cables.

Have seen it used to coat inside of tubing also but I think that is a bad idea.

Note: I think this link is to the basic document AC 43-13-1B...BEFORE a couple of updated versions that are more current. Anyhow, this was apparently accepted practice back in the day.

I wonder why that looks odd, the AC 43.13-1B CHG 1 i have shows control cables in 6-75 and (b) just says to use a preservative after removal of external corrosion, that last statement also seems strange, if a cable has external corrosion, it probably has internal corrosion, maybe its just me after a long day of magneto work, gary

Thank you Dick,

I thought I was loosing my memory! :-)

I should have looked at a older paper copy of AC43.13-1A.

Par-al-Ketone is basically a form of Cosmoline, you can use it on any steel surface where corrosion is potential. I acts like a grease until the solvents evaporate out then its like a sticky wax from my experience. Tim

I was thinking it was a wax/paraffin type of product.
