| Subject: | Re: aircraft serial number |
Thanks all for the info. I'll check this today on my own Yak 50 and on the
52's of my fellow Yak-addicts. But with what I saw in Germany, I'm convinced
that the complete history of a Yak is often very hazy. The Yak 50 I saw was
claimed to have been in the former German Democratic Republic with the
Russian Army. Then it was sold by a former Russian military man to the new
owner. The plane came with a Russian truck, and was re-assembled in
West-Germany. This took quite some time, and the plane almost never flew. So
it looks rather good, even with the original Russian paint. The engine came
from a Yak 52, according to its serial number and book. But the lack of
history makes it all suspicious. The former Soviet Union was very
bureaucratic. So they must have all the details. But I also know that
paperwork was sometimes "corrected" in order to have it all OK. And I think
that these practices subsist today.

A serial number DATA PLATE is usually located at the tail end of the
fuselage on the flat sheet metal section just in front of the rudder. It is
usually about .75" tall by about 2.5" wide and is riveted to the sheet
metal. The serial number is stamped in this plate. Using my personal Yak
52 as an example, if one were to remove any removable panel, such as
inspection panels or wing/tail feather fairings or even the cowling, the
serial number is stenciled on each part.

Dan,
Assuming you have an original Russian DA-30 unit in the rear cockpit, then the
connector is for the 3 phase 400Hz 36V power supply (from the PAG-1FP inverter)
to the T&B gyro that's imbedded with the VSI.

Production of the CJ-6 was started in 1962, theoretically the first
airplane down the line should have had the serial number 0132001. Jim
Plumlee of SC has a CJ with the serial number 0232019 and was supposed
to have been built in 1962. It is the oldest CJ that I know of.

Walt,
Thanks - - - I think. I just got word from Rich Hess who has a new 'CJ-6
G' built just 2 years ago (It has a 400 hp and metal 3 bladed prop) that his
serial number is H2S001. Maybe the Chinese are starting a new numbering
system on the CJs. Go figure.

Walt and Jim,
Jim's description is correct for aircraft placed in service with the
PLAAF and is the same with the CJ5's. Those aircraft sold "outside"
have different serial numbers. My fresh overhauled airframes all had
new S#'s issued to them. They have a serial number similar to the two
new CJ's I brought in, which is a two digit number then a dash and two
more digits, nothing like Rich Hess's S#. Like you said... go figure.
Best Christmas wishes to all,
Always Yakin,
Doug Sapp

For those who wanted copies of my magneto timing doc and newly updated CJ Annual
Checklist, I converted them to pdf files and they are available in the RPA store
under "manuals" for a small fee. Soon to come is a how-to on converting the
CJ over to the M-14P and a list of mods that I think are worth doing.
On the subject of M-14P's, now that the GBP is twice the USD and Euro pulling away
fast, the premium paid for the 360 hp is losing it's appeal. Is there hope
for hotrodding new life into tired old Huosai's? I'm mean reasonable cost overhauls
and modest hop-ups but not at the price of decreased reliability. Yep I
know about what some folks are doing now but what I'm talking about is enough
volume to meet growing demand. Possible?
