As all have said, hand propping deserves respect and training with someone who
knows how, on your type acft.
On my standard CJ, I dont have person in cockpit use start button, it allows me
to control prop movement; they are there to turn mags off if anything bad happens.
I brief hand signals for mag kill, throttle back and pumping primer to
help it catch. I pull from in front since CJ nose wheel puts the prop disk vertical.
I cross my hands on the blade so at the end of the swing they are not
crossed and make sure to carry my momentum sideways with the swing, not into
the prop.
The fact that my engine will happily start with a brisk swing on mags alone, cold,
warns that repositioning the prop at any time deserves respect.
This is good motivation to track down leaks that deplete air and develop a backup
air refill plan for days it doesnt want to start...for my engine, pre-heat
makes it much happier.

I was always surprised by the decision of Aerostar to make the 52W and
TW with both electric and air start. I assumed it was to encourage
Americans who were not familiar with air start into owning Yaks, but in
any aircraft, it does seem to me bizarre to significantly increase the
weight of the aircraft with no real advantage, by installing both
systems. For reasons that are total bureaucracy and nothing to do with
safety, I don't think there are any 52W or TW in Europe, and I'm not
sure if there is a centre of gravity issue whereby having the starter
motor; ring gear at the front of the aircraft is helpful. But certainly,
if I had the choice, I would go for air-start alone any time, and in an
aeroplane that has been properly maintained and a pilot who knows how to
operate the air start, it will always work! The problem is pilots who
think that the air start is like an electric motor, and if the engine
doesn't start immediately, continue to keep it turning on the air. Of
course with each revolution, the fuel mixture completely changes and it
will never start!

The only thing I can add is you want to assure your footing. Loose
gravel, iceie or slippery surface or even poor footing because of foot
wear.

P.s. I've seen that "Indian rope trick" in action. It was used to pull
props through to get oil out on bigger radials a lot. Never seen it used
to start one. I have visions of the engine pop starting, ripping the
rope out of hand, rope wrapping around prop hub, etc. I've propped high
compression IO550's safely. Standing behind the prop as Dennis mentioned
works well, also standing sideways in front on the prop, reaching down
with one hand and grabbing the prop end with one hand and pull as you
walk away from the prop.
Bottom line, no matter how you do it there is some kind of "Danger
Close" quite literally at hand. But when you have no other choice, it is
best not to have to attempt it for the first time. Also, leather gloves
are good to have available.

there's much safer and more efficient way of doing it than pulling a
live prop by hand. grab a piece of rope and make a pocket at one end to
envelope blade's tip, but not tight so it can slip when prop rotates
about 90deg. then pull from a distance. actually it's a standard
"ground support" tool for bigger radials.
or get rid of air start system completely. just fuggedaboutit ! have
almost new electric start kit if anyone is interested

| Subject: | Help Troubleshooting the magnetic heading indicators CJ-6A |
Hello, I have a CJ-6 and have a problem with the original heading
indicators. A while back they started processing clockwise randomly (at
about 1 deg/sec) in flight but the AN-1A Synchronizing button would bring
them back to the correct heading and they'd stay for at least a little
while. Now they don't work at all. They hold exactly 310 or 150, flipping
randomly between the two maybe a few times each flight.
The GHC-2 magnetic heading sensor looks like it's in good shape. I took it
out and the compass swings freely and correctly. All the connections at
each device look good and are secure. The ZH-4 heading indicators are in
good shape and the knob swings the card securely.
The next step I was going to take was checking the continuity of the wiring
harnesses, but I haven't been able to figure out how they work exactly. I
noticed the SBL-53 inverter seems to make a click sound/feel when I press
the AN-1A button. The manual says that the inverter drives the "LTC-1
Gyro-magnetic compass" but as far as I can read that's different than the
ZH-4 heading indicators. I'm assuming the LTC-1 is a different device that
was removed (the previous owner removed the old avionics and radio stuff
that wouldn't work in the US). But I'm also not sure how the GHC-2 and
ZH-4 system gets it's power (whether it's just 28v DC or if there is an
inverter providing AC power).
Any help would be greatly appreciated! I love reading all the messages, I
learn vicariously through and from all of you! I'm just over a year into
CJ-6 ownership and troubleshooting.

Richard,
The Electric start / dual start was a decision that I made. As you may
recall, I bought 10 new Yak-52 in late 1995. In 1998, I made a follow on
order for 12 more aircraft and had Aerostar develop the Yak 52W. (and
later the Yak 52TW). It was my specifications for the
=9CW=9D version to Aerostar. We were making an aircraft more
acceptable to the western market. The significant changes were more
fuel, hydraulic brakes, western radios etc.
One for the changes we offered to our customers was the electric start.
The thinking was that electric start provided a more comfortable way for
most western users. It also eliminated the need to carry spare
compressed air when traveling away from home base. We here in the states
tended to fly these aircraft away from home base. My thinking was you
could pretty much always find a set of jumper cables at any airport, but
seldom find high pressure compressed air. The aircraft still needed air
for the gear and flaps, the dual start was offered as an option.

Hello George =93 indeed I remember chatting to you at Oshkosh
about this, and I fully understand the rationale for electric start if
you're aiming at the US market, and I suppose that since you already
have the pneumatic system for undercarriage, you might as well keep air
start as well!
