G’Day All,

Can someone please advise of the problem with the Yak elevator and what the fix is.
I would greatly appreciate some photo’s of the problem and the fix if anyone has any.

Thanks and cheers,

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 kind of foreign object that happen to get into that area, will almost certainly jam it. Therefore it behooves one to check regularly for ANYTHING that might migrate back there. This would include anything that might fall out of one's pockets, particularly during acro. Although this is true of ANY airplane, the Yak is very susceptible. Are "fix's".

G’Day 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 “foreign object” 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

G'day Vic,

Yes, I am running a 18T.
I have 2 friends with 52's and they raised the subject with me.
Plus my LAME has a number of 52's as well as 18's that he looks after and is
also interested in any information on the subject.
I have been nominated as the gopher to source the info. Bugger is'nt it.

Thanks and cheers,
Chris.

From what I understand Chris, there WAS a Yak 52 where the elevator bellcrank cracked at the point where the elevator counterweight is mounted.  I personally have not seen a cracked elevator bellcrank.  But that certainly doesn't mean there aren't any out there.  The fix is replacing the old with a new elevator bellcrank.

The attached information should answer all your questions.

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!

From what I understand Chris, there WAS a Yak 52 where the elevator
bellcrank cracked at the point where the elevator counterweight is
mounted. I personally have not seen a cracked elevator bellcrank.
But that certainly doesn't mean there aren't any out there. The fix
is replacing the old with a new elevator bellcrank.

The attached information should answer all your questions.

G’Day 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.

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 kind of foreign object that happen to get into that area, will almost certainly jam it.  Therefore it behooves one to check regularly for ANYTHING that might migrate back there.  This would include anything that might fall out of one's pockets, particularly during acro.  Although this is true of ANY airplane, the Yak is very susceptible.  Are "fix's".

This problem has been known for a while :
Crack in elevator control system pulley - UK CAA MPD : 2000-004 (27 July 2000). See attachment.
I am surprised Yak-52 pilots are just discovering it now (after the fatal accident in Russia).
It is a required inspection - annually for Yak-52 maintained under the supervision of the UK CAA.
There are of course other important Mandatory Permit Directives (MPD) issued by the UK Civil Aviation Authority for the Yak-52 :
http://www.yakuk.com/MPD.htm
Airframe life limit (confirmed by the Yakovlev Design Bureau) :
http://www.yakuk.com/MPD1998-017R5.pdf
http://www.yakuk.com/MPD2004-006.pdf
Etc ... etc ...
