| Subject: | Re: Metal In Oil Filters |
My L29 was imported in 1994 and sat assembled in a hangar and not flown fro
m 1994 until I bought it in 2010. When I bought it, I serviced the systems
and flew it half way across the US to home and been flying for 7 years now
with no problems.=C2-=C2-My L29 was never a box or field queen so don't
know if that might have made a difference. Engines are bullet proof.

After the first flight of my plane (since import), and the associated long

rly ferrous (they stuck to my magnet).
Should I be worried? The airplane sat for a lot of years before this run.
The temps and pressures are all good, and the EGT is good. The spooldown ta
kes a while (indicated not damaged bearings), but there is a noise on spool
down (almost like a clicking) below ~200 rpm, audible from near the inlets.
I am concerned about potential corrosion/damage to the bearings from sittin
g, any thoughts?
My current plan is to do another engine run, another flight (less than 30 m
inutes), come back, and drain the oil again to see if more metal has accumu
lated. Is this reasonable?
Thanks!

I have to say, I would not fly it until you had absolute confidence that the engine
was not making metal. I would tie it down and fun it for a WHILE at flying
RPMs and then see how the filter/ oil analysis works, don't fly till your sure.
The L-29 is one of the best flying jet trainers in the world with the best safety
record. Don't be a statistic.

That=99s because I imported only top-o-the-line jets.
IMHO
We paid extra for the carbon.

Metal in your oil is not a good thing, no matter what engine your talking about.
There's a reason it's there and most likely it won't just go away.
Running the engine with metal present will only distribute the metal throughout
the engine and damage components until you have some type of failure.
Sounds like the best course of action is a new motor.
The M701 is cheap compared to compromising your health, safety and well being.
I can help you with a new M701-500
