Chris,
I assure you are referring to some crashes. There are very close
clearances of control horns to air frame in the tail of the Yaks. Any kin
d of
foreign object that happen to get into that area, will almost certainly ja
m it.
Therefore it behooves one to check regularly for ANYTHING that might
migrate back there. This would include anything that might fall out of on
e's
pockets, particularly during acro. Although this is true of ANY airplane,
the Yak is very susceptible. Are "fix's".

G=99Day Pappy,
Thanks for that.
I am fully aware of foreign objects and I believe that that was the
reason for the crash in New Zealand.
Was it a screwdriver that jammed the elevator?
What I am trying to determine, is as I understand, a problem in the tail
sector, is it the elevator bellcrank?
I was told on Sunday that the Yaks tailplanes are now subject to a 25
hour inspection schedule due to some failure.
So what is the problem?
What is the fix?
Does anyone have any photographs relating to this?
Thanks and cheers,
Chris.

I addition to the =9Cforeign object=9D item there is a
problem with fatigue cracking of the elevator bellcrank (Yak 52) and
loss of elevator control. I do not know all the details but believe
there is an airworthiness directive on the subject. Suggest you contact
Richard Goode in the UK.

Hi Chris,
this problem is specific for the 52 and and you are running an 18 T ? If I remember
correctly Andrey Gluchov has told me that the replacement items are copied
in steel to avoid cracks in the elevator aluminium bell cranks. There must have
been a series which was not manufactured according to original design.
Cheers
Vic

>From what I understand Chris, there WAS a Yak 52 where the elevator
bellcrank cracked at the point where the elevator counterweight is

that certainly doesn't mean there aren't any out there. The fix is
replacing the old with a new elevator bellcrank.

Hi Dennis;
A cracked one was found here a few months back just after the problem
was first posted on the list. It was found during an inspection
generated by that information. The list works!
