Today the chip detector light in my M14P illuminated. Nothing on the screen when removed, but this very fine wire was up in tube into which the screen fits. It's about 30mm in length and is sitting next to a 2" paper clip in the picture. It's also steel, not stainless steel. Any thoughts?
Only thing done differently lately was a 40 minute "Out of Control Flight" lesson with Skip Slyfield on Sunday. Pulled 4.5 Gs positive and 1G negative. Essentially a recovery from unusual attitudes exercise.

Blitz,
Just guessing, but it looks to me like bristles out of a steel wire brush. They are doubled over like in the photo then they are pressed into a hole in the wood handle. I'm pretty sure but since there is no good scotch offered, that's about as creative as I can get this late in the day, but I do recall finding a similar item on my medium rare, blue cheese stuffed, bison burger after cleaning my grill with a (very old) el cheapo steel wire brush.

Far too fine for safety wire. Doug's suggestion the it might be a bristle from a brush used to clean the sump during its overhaul in Russia three years ago has rational merit.

I agree. Some shops or mechanics may just be a little sloppy. My M-14 engine came right from the factory with the wrong ring in the oil land. Ran for over 400 hours before making medal.

Blitz,
I did not get the pix for some reason your original message did not come through. About the only place safety wire is used with in the engine is on the planetary gears on the gear reduction drive in the nose case. The axels are safety wired with thin gauge wire. Don't remember the gauge. If you found that in the chip detector that is the most likely origin. It will be easy to get to to repair since it is sitting right in front of your face after you pull the nose case off. Hopefully the axel has not started to out of the gear and the 8 mm nut has not spun loose. You probably caught this one early.
If memory serves me correct there are not other places in the interior of the engine that uses safety wire to secure nuts. Everything else is lock tabbed.
Sorry, I share your misery.

Looks like some sort of safety wire from upstream that migrated into the tube. Did you do an oil sample analysis?

Hi Blitz;
Your photo shows a wire of possibly less than 0.020" in dia. Could you
measure it?
How did you determine it is not stainless steel? If it is carbon steel it
will have a very strong magnetic attraction. If stainless it will have none
OR a very light magnetic attraction depending on the Ni (nickel) content of
the alloy.
I do not believe there is any carbon steel safety wire made for aviation use
and the smallest dia. available in stainless or Inconel, etc. is 0.020". At
least in Western use!
The shape of the piece is not indicative of safety wire and gives a lot of
credence to Doug's suggestion of a failed wire brush (or wheel!). Wire
wheels (and possibly hand brushes) are made with both carbon and stainless
wire with diameters down to 0.005".
If it is safety wire it will be very malleable, If a brush wire it will be
stiffer and somewhat difficult to form by hand. If less than 0.020' in dia.
that would suggest a brush wire.
Cheers;
Walt
