| Subject: | Re: CJ abeam, flap up/down |
What does the CJ 6 Chinese manual says about deploying flaps for landing?
I have been deploying flaps on my base turn, I use an angle of attack indicator,
and see it increases the angle of attack, so I push the nose at the same time
as deploying flaps.
Deploying on final does not sound like a bad idea.

Check the engagement "button/arm" adjustment that depresses the
microswitch.?? Using a flat blade screwdriver with someone in the
cockpit, depress the microswitch button and see if the light is
flickering when you first engage the microswitch manually.

What scares me about jumping is hitting the plane, and get incapacitated.
With this high survival rate of ditching in GA, is the chute still better?

I agree with Dennis in testing the switch.
One question. When you put your gear up. Do you leave the gear handle in
the up position. Or do you put it in the neutral position?

I have put a 15 foot lanyard on my chute. If I am incapacitated, the
lanyard opens the chute. If you decide to land in the water or off field,
make sure you remember to lock OPEN the canopies. If u end up upside down,
it weren't be pretty trying to get out and doubt you will.

I'll endeavor to be succinct.
About 1-2 minutes after takeoff in our CJ, climbing at 2900 rpm, the engine
runs rough for about 10-15 seconds, and then smooths out. Gets one's
attention.
Grounding testing, chocked and chained down, I get the same result at full
power, and black smoke is observed coming out of the port (left) exhaust
stack.
During the roughness:
1. Both mags check OK
2. Throttle movement has no effect
3. Wobble pumping has no effect
4. Prop movement has no effect
The analysis so far is a sticking exhaust valve, but which one? Why briefly
at high power and consequently high heat?
Compression tests are fine.
Nothing obvious appears when the valve covers are removed.
Would appreciate your thoughts.
Thanks,
... Blitz

Add a quart of Marvel Mystery Oil to the oil and go fly the airplane for
an hour or two.?? The MMO tends to clean the valve stems and valve guides
of the varnish buildup that causes valve(s) to stick. Even a couple of
quarts won't hurt it.

| Subject: | Pneumatic system - lubrication |
How much maintenance is generally required on the Yak-52 pneumatic system, and
does the lubrication level play a role?
The background to this is that I shipped my Yak from South Africa to Australia.
I'd run the Yak in South Africa for about 10 years, with the annual maintenance
being done by an expatriate Russian. During that time we never had a single
hassle with the pneumatic system. The Russian technician did tell me that they
lubricated the various undercarriage actuators in accordance with the original
manuals, which called for a fairly large amount of lubricant. I recall that
after annual services, operation of the undercarriage usually resulted in a fine
mist of oil in the cockpit which looked a bit like smoke.
Now the aircraft is in Australia. At reassembly, the Licensed Aircraft Maintenance
Engineer (LAME) insisted that the pneumatic system be completely overhauled
- including all seals and o-rings within the system. Since the aircraft had
been in a non-flying condition for a fair amount of time, I could understand that
some corrosion could have developed. (FWIW the aircraft was held up in South
Africa for 18 months due to customs issues, and it then took the local LAME
almost 3 years to reassemble).
At the first annual service after returning to flight, the LAME (different one)
reported that the pneumatic system was in very poor condition, and has replaced
all the seals in the actuators. I am rather confused by this, since a) it gave
years of faultless service in South Africa, and b) it was completely overhauled
a year ago.
My suspicion is that the system was not properly lubricated at the reassembly
overhaul. What is the experience of the List members regarding the reliability
of the pneumatic system? Is it common to have to redo the seals annually, or
is there something in the system that could be causing the problem?
Thanks
Mike
